A cup of hot tea
- For other uses, see Tea (other meanings).
Tea is a caffeineontaining beverage, made by steeping dried leaves or buds of the tea bush Camellia sinensis in hot water for a few minutes. Other herbs, spices, or fruit are sometimes added for flavour.
The term herbal tea usually refers to infusions of fruit or herbs containing no actual tea, such as rosehip tea or chamomile tea. Alternative terms for this are tisane or herbal infusion, both bearing an implied contrast with tea. This article is concerned exclusively with preparations and uses of the tea plant, Camellia sinensis, the Minnan word for which is the etymological origin of the English word tea.
About 3,000,000 tonnes of tea are produced worldwide annually.

Cultivation and classification
Tea is grown primarily in China, India, Bangladesh, Pakistan, Iran, Republic of Korea, Sri Lanka, Taiwan, Japan, Indonesia, Nepal, Australia, Argentina, and Kenya. (Note that in the tea trade, Sri Lanka and Taiwan are still referred to by their former names of Ceylon and Formosa, respectively.)
Camellia sinensisThe main types of tea are distinguished by their processing. Camellia sinensis is an evergreen shrub whose leaves, if not quickly dried after picking, soon begin to wilt and oxidize. This process resembles the malting of barley, in that starch is converted into sugars; the leaves turn progressively darker, as chlorophyll breaks down and tannins are released. The next step in processing is to stop the oxidation process at a predetermined stage by removing the water from the leaves via heating.
The term fermentation was used (probably by wine fanciers) to describe this process, and has stuck, even though no true fermentation happens (i.e. the process is not driven by microbes and produces no ethanol). Without careful moisture and temperature control, fungi will grow on tea. The fungi will cause fermentation which will contaminate the tea with toxic and carcinogenic substances. In fact, when real fermentation happens, the tea must be discarded.
Tea is traditionally classified based on the degree or period of fermentation (oxidation) the leaves have undergone:
- White tea(白茶)
- Young leaves (new growth buds) that have undergone no oxidation; the buds may be shielded from sunlight to prevent formation of chlorophyll. White tea is produced in lesser quantities than most of the other styles, and can be correspondingly more expensive than tea from the same plant processed by other methods. It is also less well-known in the western countries, though this is changing with the introduction of white tea in bagged form.
- Green tea (绿茶)
- The oxidation process is stopped after a minimal amount of oxidation by application of heat; either with steam, a traditional Japanese method; or by dry cooking in hot pans, the traditional Chinese method. Tea leaves may be left to dry as separate leaves or rolled into small pellets to make gun-powder tea. The latter process is time consuming and is typically done only with pekoes of higher quality. The tea is processed within one to two days of harvesting.
- Oolong (烏龍茶)
- Oxidation is stopped somewhere between the standards for green tea and black tea. The oxidation process will take two to three days.
- Black tea/Red tea (紅茶)
- The tea leaves are allowed to completely oxidize. Black tea is the most common form of tea in the western countries. The literal translation of the Chinese word is red tea, which may be used by some tea-lovers. However, red tea may also refer to rooibos, an increasingly popular South African tisane. The oxidation process will take around two weeks and up to one month. Black tea is further classified as either orthodox or CTC (Crush, Tear, Curl, a production method developed about 1932). Unblended black teas are also identified by the estate they come from, their year and the flush (first, second or autumn). Orthodox and CTC teas are further graded according to the post-production leaf quality by the Orange Pekoe system.
- Pu-erh (普洱茶/黑茶)
- Two forms of Pu-erh are available: green (青饼) and mature (熟饼). Mature Pu-erh is made from green Pu-erh tea leaf that has been allowed to go through a second stage of oxidation. This is done through a process similar to composting, except that both the moisture and temperature of the tea are carefully monitored. The tea is then usually compressed into various shapes including bricks, discs or spinning tops. While most teas are consumed within a year of production, pu-erh can be aged for many years to improve its flavour. Outside of Yunnan province, China where the tea is produced, the term Pu-erh is used directly to refer to the mature form of the tea. The tea is often steeped for long periods of time or even boiled (Tibetans boil it overnight). Pu-erh is considered a medicinal tea in China. Teas that undergo the composting such as mature Pu-erh are sometimes collectively referred to as Black tea (黑茶) in Chinese. This is not to be confused with the western term Black tea, which is known in Chinese as Red Tea (紅茶).
- Yellow tea (黃茶)
- Either used as a name of high-quality tea served at the Imperial court, or of special tea processed similarly to green tea, but with a slower drying phase.
- Kukicha (茎茶)
- Also called winter tea, kukicha is made from twigs and old leaves pruned from the tea plant during its dormant season and dry-roasted over a fire. Popular as a health food in Japan and in macrobiotic diets.
Blends and additives
Almost all teas in tea-bags and most other teas are blends. Though recently with improvements in the dry freeze technique and the improved infusion method, tea powder and condensed tea essence that only needs hot or cold water to make a cup of tea are sold. Blending may occur at the level of tea-planting area (e.g., Assam), or teas from many areas may be blended. The aim of blending is a stable taste over different years, and a better price. More expensive, more tasty tea may cover the inferior taste of cheaper tea.
There are various teas which have additives and/or different processing than "pure" varieties. Tea is able to easily receive any aroma, which may cause problems in processing, transportation or storage of tea, but can be also advantageously used to prepare scented teas.
Variants include:
- Breakfast tea
- Generally a blend of different black teas that are robust and full-bodied, and go well with milk. Some flavours are English, Irish and Scottish. Afternoon blends are lighter. Both blends are popular in the British Isles.
- Jasmine tea
- Spread with jasmine flowers while oxidizing, and occasionally some are left in the tea as a decoration. Many other flowers, including roses and other fragrant blooms, are used as flavouring in tea in China.
- Earl Grey tea
- Usually a mix of black teas, with essence of the citrus fruit bergamot added.
- Spiced teas
- Include the Indian chai, flavoured with sweet spices such as ginger, cardamom, cinnamon, black pepper, clove, Indian bay leaf and sometimes nutmeg are common in southern Asia and the Middle East.
- Touareg Tea
- Strong green tea with Nana mint, prepared in desert areas of North Africa and the Middle East.
- Jagertee
- A tea with rum added.
- Gen Mai Cha (genmaicha)
- A Japanese tea with roasted rice added, and favoured (as are many teas) by adherents of a macrobiotic diet.
- Lapsang souchong (正山小种 or 烟小种)
- originally from Mount Wuyi in the Fujian province of China. Lapsang souchong is a black tea which is dried over burning pine, thereby developing a strong smoky flavour.
History
Tea creation myths
- The original cup of tea was not invented but discovered as a course daily affair of the simple inhabitants in the hills of Min-nan 1
- In one story, Gautama Buddha is said to have discovered tea, when a falling tea leaf happened to land in his cup one day as he sat mating in a garden.
- Another story has it that Bodhidharma cut his eyelids off so that he wouldn't fall asleep while mating, and the first tea plants sprang up from the ground where he flung the severed eyelids.
- According to Chinese legend, the god of agriculture would chew leaves, stems, and roots of various plants to discover medicinal herbs. If he consumed a poisonous plant, he would chew tea leaves to detoxify the poison.
- In yet another story Shennong (the legendary Emperor of China and founder of Chinese medicine) was on a journey 5000 years ago, when a few leaves from a wild tea tree fell into his hot water. The emperor, known for his wisdom in the ways of science, believed that the safest way to drink water was by first boiling it. One day during a journey, the emperor noticed that leaves had fallen into his boiling water. The leaves turned the water a light-brown color and gave off an enticing aroma. The ever inquisitive and curious monarch took a sip of the brew and was pleasantly surprised by its excellent flavor and its restorative properties. He then found that tea leaves eliminated numerous other poisons from the body. Because of this, tea is considered one of the earliest Chinese medicines.
Origin and dissemination of tea
China Tea History
Regardless of this legend’s veracity, Tea has played a significant role in Asian culture for centuries as a staple beverage, a curative and a symbol of status. It is not surprising its discovery is ascribed to religious or royal origins. The fact is that the Chinese have enjoyed tea for centuries. Scholars hailed the brew as a cure for a variety of ailments. The nobility considered the consumption of good tea as a mark of their status. The common people simply enjoyed its flavor.
The tea plant has been traced to China and possibly Southeast Asia; historically the origin of tea as a medicinal herb useful for staying awake is unclear. China is considered the birthplace of tea drinking with recorded tea use in its history to at least 1000 B.C.. The use of tea as a beverage drunk for pleasure on social occasions dates from the Tang Dynasty or earlier. For its later uses, see below. The Tang dynasty writer Lu Yu 陆羽's Cha Jing 茶经 is an early work on the subject.
The Chinese are cred most for the development and cultivation of tea and the methods of its early preparation and use. The oldest written record regarding tea appeared more than 2000 years ago in China in a labor contract between a master and laborer where tea was already treated as a saleable commodity. There is no clear record regarding when human beings began consuming tea or if people in ancient times ate tea leaves or drank brewed tea. There is some evidence that tea leaves were roasted in the process. More about History of tea in China can be found here.
8th Century: Steaming Process is Introduced
The Han dynasty used tea as medicine. Tea drinking was widespread during the Tang period according to Cha Jing or Cha Ching (Classics of Tea) written around 760 by Lu Yu (729-804). The book describes how tea plants were grown, the leaves processed, and tea prepared as a beverage. It also describes how tea was evaluated. The book even discusses where the best tea leaves were produced. A form of compressed tea referred to as white tea was being produced as far back as the Tang Dynasty (618-907 A.D.). At this time in tea's history, the nature of the beverage and style of tea preparation were quite different from the way we experience tea today. Tea leaves were processed into cakes. The dried teacake, generally called “brick tea” was ground in a stone mortar. Hot water was added to the powered teacake, or the powdered teacake was boiled in earthenware kettles then consumed as a hot beverage. This special white tea of Tang was picked in early spring when the new growths of tea bushes that resemble silver needles were abundant. These "first flushes" were used as the raw material to make the compressed tea.
12th Century: Tea Culture is Introduced
During the Song Dynasty (960-1279), production and preparation of all tea changed. The tea of Song included many loose-leaf styles (to preserve the delicate character favored by the court society), but a new powdered form of tea emerged. Tea leaves were picked and quickly steamed to preserve their color and fresh character. After steaming, the leaves were dried. The finished tea was then ground into fine powders that were whisked in wide bowls. The resulting beverage was highly regarded for its deep emerald or iridescent white appearance and its rejuvenating and healthy energy. Drinking tea was considered stylish among government officers and intellectuals during the Southern Song period in China (12th to 13th centuries). They would read poetry, write calligraphy, paint, and discuss philosophy while enjoying tea. Sometimes they would hold tea competitions where teas and tea instruments were judged. When Song Dynasty emperor Hui Zhong proclaimed white tea to be the culmination of all that is elegant, he set in motion the evolution of an enchanting variety.
This Song style of tea preparation incorporated powdered tea and ceramic ware in a ceremonial aesthetic known as the Song tea ceremony. Japanese monks traveling to China at this time had learned the Song preparation and brought it home with them. Although it later became extinct in China, this Song style of tea evolved into the Japanese tea ceremony, which endures today. This Song style of tea preparation incorporated powdered tea and ceramic ware in a ceremonial aesthetic known as the Song tea ceremony.
Japanese monks traveling to China at this time had learned the Song preparation and brought it home with them. Although it later became extinct in China, this Song style of tea evolved into the Japanese tea ceremony, which endures today. Many forms of white tea were made in the Song Dynasty due to the discerning tastes of the court society. Hui Zhong, who ruled China from 1101-1125, referred to white tea as the best type of tea, and he has been cred with the development of many white teas in the Song Dynasty, including "Palace Jade Sprout" and "Silver Silk Water Sprout."
Producing white teas was extremely labor-intensive. First, tea was picked from selected varietals of cultivated bushes or wild tea trees in early spring. The tea was immediately steamed, and the buds were then selected and stripped of their outer, unopened leaf. Only the delicate interior of the bud was reserved to be rinsed with spring water and dried. This process produced white teas that were paper thin and small.
Once processed, the finished tea was distributed and often given as a tribute to the Song court in loose form. It was then ground to a fine, silvery-white powder that was whisked in the wide ceramic bowls used in the Song tea ceremony. These white powder teas were also used in the famous whisked tea competitions of that era.
13th Century: Tea Roasting Process is Introduced
In China, steaming tea leaves was the primary process used for centuries in the preparation of brewed tea. After the transition from compressed tea to the powdered form, the production of tea for trade and distribution changed once again. The Chinese learned to process tea in a different way in the mid-13th century. Tea leaves were roasted and then crumbled rather than steamed. This is the origin of today’s loose teas and the practice of brewed tea.
In 1391, the Ming court issued a decree that only loose tea would be accepted as a "tribute." As a result, loose tea production increased and processing techniques advanced. Soon, most tea was distributed in full-leaf, loose form and steeped in earthenware vessels.
17th Century: Tea Fermentation Process is Introduced
In 17th century China, various types of tea plants were grown in different regions and numerous advances were made in tea production. In the southern part of China, tea leaves were sun dried and half fermented. However, this method was not common in the rest of China.
Late 18th and 19th Century: Mass Production is Introduced
Modern-day white teas can be traced to the Qing Dynasty in 1796. Back then, teas were processed and distributed as loose tea that was to be steeped, and they were produced from "chaicha," a mixed-variety tea bush. They differed from other China green teas in that the white tea process did not incorporate de-enzyming by steaming or pan-firing, and the leaves were shaped. The silver needle white teas that were produced from the "chaicha" tea bushes were thin, small and did not have much silvery-white hair.
It wasn't until 1885 that specific varietals of tea bushes were selected to make "Silver Needles" and other white teas. The large, fleshy buds of the "Big White," "Small White" and "Narcissus" tea bushes were selected to make white teas and are still used today as the raw material for the production of white tea. By 1891, the large, silvery-white down-covered Silver Needle was exported, and the production of White Peony started around 1922.
Tea History Japan
9th Century: Importing Tea and Culture
The earliest known references to green tea in Japan is in a text written by a Buddhist monk in the 9th century. Tea became a drink of the religious classes in Japan when Japanese priests and envoys sent to China to learn about its culture brought tea to Japan. The first form of tea brought from China was probably in a teacake. Ancient recordings indicate the first batch of tea seeds were brought by a priest named Saicho in 805 and then by another named Kukai in 806. It became a drink of the royal classes when Emperor Saga, the Japanese emperor, encouraged the growth of tea plants. Seeds were imported from China, and cultivation in Japan began.
12th Century: Kissa Yojoki - the Book of Tea
In 1191, the famous Zen priest Eisai (1141-1215) brought back tea seeds to Kyoto. Some of the tea seeds were given to the priest Myoe Shonin, and became the basis for Uji tea. The oldest tea specialty book in Japan, Kissa Yojoki (how to stay healthy by drinking tea) was written by Eisai. The two-volume book was written in 1211 after his second and last visit to China. The first sentence states, “Tea is the ultimate mental and medical remedy and has the ability to make one’s life more full and complete.” The preface describes how drinking tea can have a positive effect on the five vital organs, especially the heart. It discusses tea’s medicinal qualities which include easing the effects of alcohol, acting as a stimulant, curing blotchiness, quenching thirst, eliminating indigestion, curing beriberi disease, preventing fatigue, and improving urinary and brain function. Part One also explains the shapes of tea plants, tea flowers and tea leaves and covers how to grow tea plants and process tea leaves. In Part Two, the book discusses the specific dosage and method required for individual physical ailments.
Eisai was also instrumental in introducing tea consumption to the warrior class, which rose to political prominence after the Heian Period. Eisai learned that the general Samurai (Shogun) Sanetomo Minamoto had a habit of drinking too much every night. In 1214, Eisai presented a book he had written to the general, lauding the health benefits of tea drinking. After that, the custom of tea drinking became popular among the Samurai.
Very soon, green tea became a staple among cultured people in Japan -- a brew for the gentry and the Buddhist priesthood alike. Production grew and tea became increasingly accessible, though still a privilege enjoyed mostly by the upper classes.
13th Century: Roasting Process Introduced to Japan
In the 13th century Ming dynasty, southern China and Japan enjoyed much cultural exchange. Significant merchandise was traded and the roasting method of processing tea became common in Kyushu, Japan. Since the steaming (9th century) and the roasting (13th century) method were brought to Japan during two different periods, these teas are completely distinct from each another.
16th Century: The Tea Culture Emerges
The pastime made popular in China in the twelfth and thirteenth centuries -- drinking tea, reading poetry, writing calligraphy, painting, and discussing philosophy while enjoying tea – eventually became popular in Japan and with Samurai society. The modern tea ceremony developed over several centuries by Zen Buddhist monks under the original guidance of the monk Sen-no Rikyu (1522-1591). In fact, both the beverage and the ceremony surrounding it played a prominent role in feudal diplomacy. Many of the most important negotiations among feudal clan leaders were carried out in the austere and serene setting of the tea ceremony. By the end of the sixteenth century, the current “Way of Tea” was established. Eventually, green tea became available to the masses, making it the nation's most popular beverage.
18th Century: Modern Japanese Green Tea Introduced
Soen Nagatani developed Japanese Sencha (unfermented green tea) in 1740. Sencha uses dried crumbled tea leaves and is now a mainstay in Japan. Rather than being ground and mixed with hot water, steamed tea leaves are pressed, rolled and dried into loose tea.
19th Century: Machines Replace Hand Rolling
At the end of the Meiji period (1868-1912), machine manufacturing of green tea was introduced and began replacing handmade tea. Machines took over the processes of primary drying, tea rolling, secondary drying, final rolling, and steaming.
20th Century: Automation Creates Superior Tea
Automation contributed to improved quality control and reduced labor. Sensor and computer controls were introduced to machine automation so that unskilled workers can produce superior tea without compromising in quality. Certain regions in Japan are known for special types of green tea, as well as for teas of exceptional quality, making the leaves themselves a highly valued commodity. This combination of Nature’s bounty and manmade technical breakthroughs combine to produce the most exceptional green tea products sold on the market today. Today, roasted green tea is not as common in Japan and powdered tea is used in ceremonial fashion.
21th Century: Green Tea's Role in Japanese Society
Green tea's traditional role in Japanese society is as a drink for special guests and special occasions. Green tea is served in many companies during afternoon breaks. The Japanese have a custom of buying confectioneries for their colleagues when on vacations or business trips. These snacks are usually opened and enjoyed with green tea. If you visit a Japanese company on business, you are likely to be offered a cup of tea to sip during your meeting. At a restaurant, a cup of green tea is often served with meals at no extra charge, with as many refills as desired. The best traditional Japanese restaurants take as much care in choosing the tea they serve as in preparing the food itself. When guests arrive, Japanese brew a pot of green tea. A thermos full of green tea is also a staple on family or school outings as an accompaniment to bento (box lunches). Families oftentimes bring along proper Japanese teacups, to enhance the enjoyment of the traditional drink. The strong cultural association the Japanese have with green tea has made it the most popular beverage to drink with traditional Japanese cuisine, such as sushi, sashimi and tempura. Many Japanese are still taught the proper art of the centuries-old Tea Ceremony as well. Still, the Japanese now enjoy green tea processed using state of the art technology that accentuates both its health benefits and its taste. Today, hand pressing -- a method demonstrated to tourists -- is taught only as a technique preserved as a part of the Japanese cultural tradition.
As the Venetian explorer Marco Polo failed to mention tea in his travel records, it is conjectured that the first Europeans to encounter tea were either Jesuits living in Beijing who attended the court of the last Ming Emperors; or Portuguese explorers visiting Japan in 1560. Russia discovered tea in 1618 after a Ming Emperor of China offered it as a gift to Czar Michael I of Russia.
Soon imported tea was introduced to Europe, where it quickly became popular among the wealthy in France and the Netherlands. English use of tea dates from about 1650 and is attributed to Catherine of Braganza (Portuguese princess, and queen consort of Charles II of England).

Exploitation, supply and demand
Global tea production by country. Source: The high demand for tea in Britain caused a huge trade deficit with China. The British set up tea plantations in colonial India to provide their own supply. They also tried to balance the trade deficit by selling opium to the Chinese, which later led to the First Opium War in 1838–1842.
The Boston Tea Party was an act of uprising in which Boston residents destroyed crates of British tea in 1773, in protest against British tea and taxation policy. Prior to the Boston Tea Party, residents of Britain's North American 13 colonies drank far more tea than coffee. In Britain, coffee was more popular. After the protests against the various taxes, Americans stopped drinking tea as an act of patriotism. Similarly, Britons slowed their consumption of coffee.
These days, contradicting tea economies do exist. Tea farmers in the Republic of Korea, Japan, Taiwan and China often enjoy better incomes compared to farmers in black tea producing countries.
The word tea
The Chinese character for tea is 茶, but it is pronounced very differently in the various Chinese dialects. Two pronunciations have made their way into other languages around the world. One is 'te' (POJ: tê) which comes from the Minnan dialect spoken around the port of Xiamen (Amoy). The other is 'cha', used by the Cantonese dialect spoken around the ports of Guangzhou (Canton) and Hong Kong, as well as in the Mandarin dialect of northern China. Yet another different pronunciation is 'zoo', used in the Wu dialect spoken around Shanghai.
Languages that have Te derivatives include Armenian, Danish, Dutch ('thee'), English ('tea'), Finnish, Estonian ('Tee'), Faroese, French ('Thé'), German ('Tee'), Hebrew ('תה', /te/ or /tei/), Hungarian ('tea'), Icelandic, Indonesian, Italian ('tè'), Latvian, Malay, Norwegian, Polish (herbata from Latin herba the), Singhalese, Spanish (té), Swedish ('te'), Tamil ('thè'), Yiddish, and scientific Latin.
Those that use Cha or "Chai" derivatives include Albanian, Arabic, Bulgarian,Bangla, Croatian, Czech, Greek, Hindi,Urdu Japanese ('茶', 'ちゃ', 'cha'), Korean, Nepali ('chia'), Persian, Portuguese ('chá'), Russian, Ukrainian, Romanian, ('чай', 'chai'), Serbian, Slovak Slovene ('čaj'), Swahili, Tagalog, Thai, Tibetan, Turkish (çay), Malayalam,and Vietnamese ('chè' or 'trà').
It is tempting to correlate these names with the route that was used to deliver tea to these cultures, but this correspondence does not follow. For example, most British trade went through Canton, which uses cha.
In Ireland, or at least in Dublin, the term "cha" is sometimes used for tea, with "tay" as a common pronunciation throughout the land, and "char" was a common slang term for tea throughout British Empire and Commonwealth military forces in the 19th and 20th centuries, crossing over into civilian usage. In North America, the word "chai" is used to refer almost exclusively to the Indian "chai" (or "masala chai") beverage.
Perhaps the only place in which a word unrelated to tea is used to describe the beverage is South America (particularly Andean countries), because a similar stimulant beverage, hierba mate, was consumed there long before tea arrived. In various places of South America, any tea is referred to as mate.
Tea culture
Tea is often drunk at social events, such as afternoon tea and the tea party. It may be drunk early in the day to heighten alertness; it contains theophylline and bound caffeine (sometimes called "theine"), although there are also decaffeinated teas.
There are tea ceremonies which have arisen in different cultures, Japan's complex, formal and serene one being the most known. Other examples are the Korean tea ceremony or some traditional ways of brewing tea in Chinese tea culture.
China
Due to the importance of tea in Chinese society and culture, tea houses can be found in most Chinese neighborhoods and business districts. Chinese-style tea houses offer dozens of varieties of hot and cold tea concoctions. They also serve a variety of tea-friendly and/or tea-related snacks. Beginning in the late afternoon, the typical Chinese tea house quickly becomes packed with students and business people, and later at night plays host to insomniacs and night owls simply looking for a place to relax. Formal tea houses also exist. They provide a range of Chinese and Japanese tea leaves, as well as tea making accoutrements and a better class of snack food. Finally there are the tea vendors, who specialize in the sale of tea leaves, pots, and other related paraphernalia.
History
In China, at least as early as the Tang Dynasty, tea was an object of connoisseurship; in the Song Dynasty formal tea-tasting parties were held, comparable to modern wine tastings. As much as in modern wine tastings, the proper vessel was important and much attention was paid to matching the tea to an esthetically appealing serving vessel.
Historically there were two phase of tea drinking in China based on the form of tea that was produced and consumed, namely: Tea bricks versus Loose Leaf Tea.
Tea Bricks
Tea served prior to the Ming Dynasty was typically made from tea bricks. Upon harvesting, the tea leaves were either partially dried or were thoroughly dried and ground before being pressed into bricks. The pressing of Pu-erh is likely a vestige of this process. Tea bricks were also sometimes used as currency. To improve its resiliency as currency, some tea bricks were mixed with binding agents such as blood. Serving the tea from tea bricks required multiple steps:
- Toasting: Tea bricks are usually first toasted over a fire to destroy any mold or insects that may have burrowed into the tea bricks. Such infestation sometimes occur since the bricks were stored openly in warehouses and storerooms. Toasting also likely imparted a pleasant flavour to the resulting tea.
- Grinding: The tea brick was broken up and ground to a fine powder resembling Japanese powdered tea (Matcha).
- Whisking: The powdered tea is mixed into hot water and frothed with a whisk before serving. The colour and patterns formed by the powdered tea is enjoyed while the mixture is being imbibed.
The ground and whisked teas used at that time called for dark and patterned bowls in which the texture of the tea powder suspension can be enjoyed. The best of these bowls, glazed in patterns with names like oil spot, partridge-feather, hare's fur, and tortoise shell, are highly valued today. The patterened holding bowl and tea mixture was often lauded in the period's poetry with phrases such as "partridge in swirling clouds" or "snow on hare's fur". Tea in this period was enjoyed more for its patterns and less for its flavour. The practice of using powdered tea can still be seen in the Japanese Tea ceremony or Chado
Loose-Leaf Tea
After 1391, Emperor Hung-wu, the first Emperor of the Ming Dynasty, decreed that tributes of tea to the court were to be changed from brick to loose-leaf form. The imperial decree quickly transformed the tea drinking habits of the people, changing from whisked teas to steeped teas. The arrival of the new method for preparing tea also required the creation or use of new vessels.
- The tea pot was needed such that the tea leaves can be steeped separately from the drinking vessel for an infusion of proper concentration. The tea also needs to be kept warm and the tea leaves must be separated from the resulting infusion when required.
- Tea caddies and containers also became necessary in order to keep the tea and conserve its flavour. This due to the fact that tea leaves do not preseve as well as tea bricks. Furthermore, the natural aroma tea became the focus of the tea drinking due to the new preparation method.
- A change in chinese tea drinking vessels was also evident at this point. Smaller bowls with plain or simple designs on the interior surfaces were favoured over the larger patterned bowls used for enjoying the patterns created by powdered teas. Tea drinking in small bowls and cups was likely adopted since it gathers and directs the fragrant steam from the tea to the nose and allows for better appreciation of the tea's flavour.
This is the current and preferred method of preparing tea in Chinese culture.
Vietnam
Tea is cultivated extensively in the north of the country, making Vietnam one of the world's largest exporters. The tea is normally drunk green, and strongly brewed. The word in the Vietnamese language is tra (pronounced cha) or che.
Britain
The British are amongst the largest per capita tea consumers in the world - each person consuming on average 2.5 kg per year. The popularity of tea dates back to the 19th Century when India was part of the British Empire, and British interests controlled tea production in the subcontinent. Tea initially was such a luxury that the teapoy, a dedicated piece of furniture, was developed for storing it. For most people in Britain tea drinking is not the delicate, refined cultural expression that much of the world imagines - a cup (or more often a mug) of tea is something drunk several times a day quite unceremoniously. "Tea" is not only the name of the beverage, but of a late afternoon light meal, irrespective of beverage drunk. Frequently (outside the UK) this is referred to as "high tea", however in the UK high tea is an evening meal. The term evidently comes from the meal being eaten at the "high" (main) table, rather than the smaller table common in living rooms. Tea is usually served with milk (not cream) and sugar, although taking sugar is increasingly less common. There is a tradition of tea rooms in the UK which usually provide the traditional fare of cream and jam on scones, but these have declined in popularity since World War II. In Devon and Cornwall particularly, cream teas are a speciality. Lyons Corner Houses were a successful chain of such establishments.
Industrial Revolution
Some scholars suggest the tea played a role in British industrial revolution. Afternoon tea possibly became a way to increase the number of hours laborers could work in factories; the stimulants in the tea, accompanied by sugary snacks would give workers energy to finish out the days work. Further, tea helped alleviate some of the consequences of the urbanization that accompanied the industrial revolution: drinking tea required boiling one's water, thereby killing water-borne diseases like dysentery, cholera, and typhoid 2.
Hong Kong
The English-style tea has evolved into a new local style of drink, the Hong Kong-style milk tea, more often simply "milk tea", in Hong Kong. It is popular at cha chaan tengs and fast food shops such as Café de Coral and Maxims Express. Traditional Chinese tea, including green tea, flower tea, jasmine tea and Pu-erh tea, are also common, and are served at dim sum restaurant during yum cha.
Iran
Tea found its way to Persia (Iran) from India and soon became the national drink. The whole part of northern Iran along the shores of the Caspian Sea is suitable for the cultivation of tea. Especially in the Gilan province on the slopes of Alborz large areas are under tea cultivation and millions of people work in the tea industry for their livelihood. That region covers a large part of Iran's need for tea. Iranians have one of the highest per capita rate of tea consumption in the world and from old times every street has had a Châikhâne (Tea House). Châikhâne's are still an important social place. Iranians traditionally drink tea by pouring it into the saucer and putting a lump of sugar in the mouth before drinking the tea. This is seen nowhere else in the world.
Ireland
Ireland has, for a long time, been one of the biggest per-capita consumers of tea in the world. The national average is four cups per person per day, with many people drinking six cups or more.
As with Britain tea in Ireland is usually taken with milk and/or sugar. The two main brands of tea sold in Ireland are Lyons and Barrys. There is a considerable amount of light-hearted debate over which brand is superior. The Irish love of tea is perhaps best illustrated by the stereotypical housekeeper, Mrs Doyle in the popular sit-com Father Ted.
India
One of the world's largest producers, tea is popular all over India as a breakfast and evening drink. It is often served as masala chai with milk and sugar, and sometimes scented. Almost all the tea consumed is black Indian tea. Usually tea leaves are boiled in water while making tea, and milk is added.
Offering tea to almost every visitor to a family is a cultural norm. Tea has entered the common idiom; for example, asking money for "chai-pani" means asking for a tip; in certain states, it may mean asking for a bribe.
Sri Lanka
In Sri Lanka, tea is served in the English style, with milk and sugar, but the milk is always warmed. Tea is a hugely popular beverage among the Sri-Lankan people, and part of its land is surrounded by the many hills of tea plantations that spread for miles and miles round. Drinking tea has become part of the culture of Sri Lanka.
Tea from Sri Lanka, acclaimed as the best tea in the world has its inherent unique characteristics and reputation running through more than a century. The influence of climatic conditions of its plantation imparts to the product a variety of flavors and aromas, synonymous with quality
Turkey
As pictured, Turkish tea or Çay is produced on the eastern Black Sea coast, which has a mild climate with high precipitation and fertile soil. Turkish tea is prepared in a samovar and can be served strong ("koyu"/dark) or weak ("açık"/light). It is drunk from small glasses in order to show the colour of the tea, with lumps of beetroot sugar. To a lesser extent than in other Muslim countries, tea replaces alcohol as the social beverage.
Russia
In Russia, it is customary to drink tea brewed separately in a teapot and diluted with freshly boiled water ('pair-of-teapots tea', 'чай парой чайников'). The traditional implement for boiling water for tea used to be the samovar (and sometimes it still is). The podstakannik, or tea glass holder (literally "under the glass"), is also a part of Russian tea tradition. Tea is a family event, and is usually served with sugar and lemon, and an assortment of jams, pastries and confections, including AND1lt;em>pastilaAND1lt;/em>, pressed apple paste.
Czech Republic
Specific tea culture developed in the Czech Republic in recent years, including many styles of tearooms. Despite having the same name, they are mostly different from the British style tea rooms. Pure teas are usually prepared with respect to their country of origin and good tea palaces may offer 80 teas from almost all tea-producing countries. Different tea rooms have also created various blends and methods of preparation and serving.
Commonwealth countries
Afternoon tea and the variant cream tea (called Devonshire Tea in Australia) is the staple "tea ceremony" of the English speaking Commonwealth countries, available in homes and tea rooms throughout the United Kingdom, Australia, India, Africa and New Zealand, although in most of these places it is no longer a daily routine. . Note that "tea" may also refer to a meal in Commonwealth nations, as in England, regardless of the beverage served with the meal. This could lead to confusion over the meaning of an invitation to "tea". The solution, in countries such as New Zealand, is to refer to the drink as a "cuppa" (as in a "cup of tea").
United States
Afternoon tea is rarely served in the United States except in ritualized special occasions such as the tea party or an afternoon out at a high-end hotel or restaurant, which may also have cream teas on the menu. In the United States, about 80% of the tea consumed is served cold, or iced. Iced tea can be purchased, like soda, in canned or bottled form at vending machines and convenience stores; usually, this pre-made tea is sweetened, and sometimes some other flavouring, such as lemon or raspberry, is added. Also, like soda, it can be purchased as a fountain drink, though in some establishments it is pumped from a Bag-In-Box, and in others, from a separate container near the fountain that contains freshly brewed tea. Sometimes there are two containers, one with sweet tea and one with unsweetened tea. In addition to tea bags and loose tea, powdered "instant iced tea mix" is available in stores. This is made by preparing tea and then dehydrating it, similar to instant coffee.
Iced tea is more frequently ordered during periods of hot weather, and hot tea is likewise more common in cold weather. Any confusion when one is visiting different parts of the country can easily be solved by explicitly asking for either "hot tea" or "iced tea". Beware, however, that "iced tea" may, or may not, be presweetened, depending on the restaurant. The reason for the presweetening is that it may be difficult to dissolve sugar in iced tea, even with constant stirring. The result can be insufficiently sweetened tea and/or gritty, undissolved sugar crystals in the tea.
Iced tea's popularity in the United States has led to an addition to standard flatware sets; the iced tea spoon is a standard flatware teaspoon, but with a long handle, suitable for stirring sugar into the taller glasses commonly used for iced tea.
Iced tea debuted in 1904 in the United States.
Hot tea is often consumed "black" but sugar or honey can be added; milk or creamer is less common. It is also common for tea to be flavoured by adding a slice of lemon, or lemon juice. When cream is added to tea, it may be called "English style".
Visitors from countries where tea consumption is more ubiquitous frequently complain that American restaurants are not familiar with proper tea preparation. Instead of pouring boiling water over tea leaves or a tea bag, waiters usually bring the customer a tea bag and a cup (or small pot) of hot water in which to dunk it. If the customer is lucky, the water has just been boiled, but often it has been sitting for a while and there is no way to know.
Traditionally, red and white teas were difficult to find in the United States, and even green tea was uncommon; however, they have recently become more popular. Recently, many coffee houses have begun to serve a milky, sweet, spiced tea called "chai", based on Indian "masala chai". Bubble tea from Taiwan has also become popular in the United States in recent years. This beverage contains spheres of sweet tapioca, which settle to the bottom of the glass or cup prior to serving.
Decaffeinated tea is widely available in the United States, for those who wish to reduce the negative physiological effects of caffeine.
U.S. regional tea traditions
Sweet tea, with sugar or corn syrup added (usually while the tea is still hot from brewing), the mixture then being cooled with ice, is ubiquitous in the Southern U.S. states. In these states, when a person says "tea", he or she normally means sweetened iced tea.
In the North, "tea" generally means the hot beverage.
In Texas, iced tea (pronounced "ahstee" in dialect) almost always means freshly-brewed unsweetened tea, generally served in a tall glass and garnished with a lemon wedge. Sweeteners are then added by the customer (or not) according to taste. Free refills are a matter of course in most restaurants.
Sun tea is frequently brewed in temperate areas by placing tea and water together in a glass jar left outdoors in direct sunlight. Steeping times are necessarily long. Tea may also be brewed with no heat at all by simply immersing the tea bags or infuser in room-temperature water and allowing a period of several hours (typically overnight) for steeping.
Alcoholic "tea"
The so-called Long Island Iced Tea usually contains no tea; it is an alcoholic cocktail that looks like and (if made correctly) tastes similiar to iced tea. A variant recipe uses actual iced tea as a mixer.
Historical background
During the colonial period, tea and tea taxes were a bone of contention between the American Colonies and England. This led to the Boston Tea Party, a precipitating event of the American Revolution, where angry Colonists destroyed the tea cargo of three British ships by dumping them into Boston Harbor. Boycotts of tea by the colonists during this period led to an increase in consumption of other beverages, such as coffee. To this day, coffee remains more popular than tea in the United States.
Japan
A Japanese man performs a tea ceremonyGreen tea (ryoku-cha) is very popular in Japan. Simply ordering cha (tea) or o-cha normally brings green tea. Specialty shops sell vast varieties of teas, as do sections in supermarkets. In cafeterias and lunch-type restaurants, hot or cold green tea usually accompanies the meal according to the customer's preferences. It is the beverage of the workplace, and employees drink it during breaks in the day. Hosts provide green tea to visitors to the home or office by dispensing hot water from insulated electric pots through a strainer containing leaves into a ceramic teapot.
Black tea, often with milk or lemon, is served in Western style restaurants. Most of the ubiquitous vending machines also carry a wide selection of both hot and cold bottled teas. Oolong tea enjoys considerable popularity.
Historically, the rituals and the traditional dark pottery of China were adopted in Japan beginning in the 12th century, and gave rise to the Japanese tea ceremony, which took its final form in the 16th century. The tea ceremony uses a strong, bitter infusion of powdered green tea. This matcha is also a flavouring in wagashi, kakigori, and ice cream.
Major tea-producing areas in Japan include Shizuoka Prefecture and the city of Uji in Kyoto Prefecture.
Other infusions bearing the name cha are barley tea (mugi-cha), buckwheat tea (soba-cha), and hydrangea tea (ama-cha).
Taiwan
Recently, bubble tea from Taiwan has become an extremely popular drink among young people around the world. This Asian fad spread to the United States in 2000, where it is generally called "bubble tea", "pearl milk tea", or "Boba". (See news) Additionally, bubble tea can now be found in major American and European cities such as London, Los Angeles, New York, and Paris.
Wu-Wo Tea Ceremony
Wu-Wo Tea Ceremony began in Taiwan. Grand Master Tsai, Rong Tsang the director of “Lu-Yu Tea Culture Institute” and the founder of the “Wu-Wo Tea Ceremony”; he has been an active part in the growth of this once small group from Taiwan (almost twenty years ago) to what is now an International Organization.
Tibet
Butter, milk, salt, and sugar are added to brewed tea and churned to form a hot drink called Po cha in Tibet. Traditionally it is made with a domestic brick tea and yak's milk, then mixed in a churn for several minutes. Using a generic black tea, milk and butter, and shaking or blending work well too. (see recipe)
Tea preparation
A Japanese teapotThis section describes the most widespread method of making tea. Completely different methods are used in North Africa, Tibet and perhaps in other places.
The best way to prepare tea is usually thought to be with loose tea placed either directly in a teapot or contained in a tea infuser, rather than a teabag. However, perfectly acceptable tea can be made with teabags. Some circumvent the teapot stage altogether and brew the tea directly in a cup or mug.
Historically in China, tea is divided into first, second, third, and fourth and fifth infusions. The first infusion of tea made is immediately poured out to wash the tea, and then, the second and further infusions are then had. The third through fifth are nearly always considered the best infusions of tea, although different teas open up differently, and may require more infusions of boiling water to bring them to life.
- Black Tea
- The water for black teas should be added at the boiling point (100 °C or 212 °F), except for very delicate Darjeeling teas, where slightly lower temperatures are recommended. This will have as large an effect on the final flavour as the type of tea used. The most common fault when making black tea is to use water at too low a temperature. Since boiling point drops with altitude, this makes it difficult to brew black tea properly in mountainous areas. The tea should not be allowed to steep for less than 30 seconds or more than about five minutes (a process known as brewing or dialectally mashing in the UK): after that, tannin is released, which counteracts the stimulating effect of the theophylline and caffeine and makes the tea bitter (at this point it is referred to as being stewed in the UK).
- Green Tea
- Water for green tea, according to most accounts, should be around 80 °C to 85 °C (176 °F to 185 °F); the higher the quality of the leaves, the lower the temperature. Preferably, the container in which the tea is steeped; the mug or teapot should also be warmed beforehand (usually by swirling a little hot water around it then pouring it out) so that the tea does not immediately cool down.
- Oolong Tea
- Oolong teas should be brewed around 90 °C to 100 °C (194 °F to 212 °F). The brewing vessel should be warmed before brewing the tea as mentioned in the Green Tea section above. Yixing clay teapots are the ideal brewing vessel for oolong tea. For best results use spring water, as the minerals in spring water tend to bring out more flavour in the tea.
- Premium or Delicate Tea
- Some teas, especially green teas and delicate Oolong or Darjeeling teas, are steeped for shorter periods, sometimes less than 30 seconds. Using a tea strainer separates the leaves from the water at the end of the brewing time if a tea bag is not being used.
- Serving
- In order to preserve the pre-tannin tea without requiring it all to be poured into cups a second teapot is employed. The steeping pot is best unglazed earthenware; Yixing pots are the best known of these, famed for the high quality clay from which they are made. The serving pot is generally porcelain, which retains the heat better. Larger teapots are a post 19th-century invention, as tea before this time was very rare and very expensive.
- Experienced tea-drinkers often insist that the tea should not be stirred around while it is steeping (sometimes called winding in the UK). This, they say, will do little to strengthen the tea, but is likely to bring the tannic acids out in the same way that brewing too long will do. For the same reason one should not squeeze the last drops out of a teabag; if you want stronger tea, use more leaves or bags.
- Additives
- Popular additives to tea include sugar or honey, lemon, milk, and fruit jams. Most connoisseurs eschew cream because it overpowers the flavour of tea. The exception to this rule is with very hearty teas such as the East Friesian blend. Milk, however, is thought to neutralize remaining tannins and reduce acidity.
- When taking milk with tea, some add the tea to the milk rather than the other way around. If the milk is chilled, this avoids scalding the milk, which leads to a better emulsion and nicer taste. The socially 'correct' method is to add the milk after the tea, but this convention was established before the invention of the refrigerator. Adding the milk first also makes a milkier cup of tea with sugar harder to prepare as there will be no hot liquid in the cup to dissolve the sugar effectively. Of course, if the tea is being brewed in a mug, the milk must be added after the tea bag is removed.
- In the United Kingdom, adding the milk first is historically considered a lower-class method of preparing tea; the upper classes always add the milk last. The origin of this distinction is said to be that the rougher earthenware mugs of the working class would break if boiling-hot tea was added directly to them, whereas the fine glazed china cups of the upper class would not. It is now considered by most to be a personal preference.
Enjoying tea the "modern" way
- Tea Bag
- Tea leaves are packed into a small (usually paper) tea bag. It is easy and convenient, making tea bags popular for many people nowadays. However, because fannings and dust from modern tea processing are also included in most tea bags, it is commonly held among tea afficianados that this method provides an inferior taste and experience. The paper used for the bag can also be tasted by many which can detract from the tea's flavour.
- Additional reasons why bag tea is considered less flavourful include:
-
- Dried tea loses its flavour quickly on exposure to air. Most bag teas (although not, admittedly, all) contain leaves broken into small pieces; the great surface-area-to-volume ratio of the leaves in tea bags exposes them to more air, and therefore causes them to go stale faster. Loose tea leaves are likely to be in larger pieces, or to be entirely intact.
- Breaking up the leaves for bags extracts flavourful oils.
- Good loose-leaf teas tend to be vacuum packed.
- Loose tea
- The tea leaves are packaged loosely in a canister or other container. The portions must be individually measured by the consumer for use in a cup, mug or teapot. This allows greater flexibility, letting the consumer brew weaker or stronger tea as desired, but convenience is sacrificed. Strainers, "tea presses", filtered teapots and infusion bags are available commercially to avoid having to drink the floating loose leaves. A more traditional, yet perhaps more effective way around this problem is to use a three-piece lidded teacup, called a gaiwan. The lid of the gaiwan can be tilted to hold back the leaves while sipping the tea.
Tea cards
In the United Kingdom a number of varieties of loose tea sold in packets from the 1940s to the 1980s contained tea cards. These were illustrated cards roughly the same size as cigarette cards and intended to be collected by children. Perhaps the best known were Typhoo tea and Brooke Bond PG Tips the latter of whom also provided albums for collectors to keep their cards in. Some renowned artists were used to illustrate the cards including Charles Tunnicliffe. Many of these card collections are now valuable collectors' items.
