Polyphenols in tea include flavonoids, epigallocatechin gallate (EGCG), and other catechins. The most important chemicals in tea are the tannins, or polyphenols, which are colourless, bitter-tasting substances that give the drink its astringency. When acted upon by an enzyme called polyphenol oxidase, polyphenols acquire a reddish colour and form the flavouring compounds of the beverage. Certain volatile oils contribute to the aroma of tea, and also contributing to beverage quality are various sugars and amino acids. The first published account of methods of planting, processing, and drinking came in 350 ce.

- Tibetans and other Himalayan peoples traditionally drink tea with milk or yak butter and salt.
- In 1848, Robert Fortune was sent by the East India Company on a mission to China to bring the tea plant back to Great Britain.
- Caffeine makes up about 3% of tea’s dry weight, which translates to between 30 and 90 milligrams per 250-millilitre (8+1⁄2 US fl oz) cup depending on the type, brand, and brewing method.
- The popular green tea is often served after every meal in the Pashtun belt of Balochistan and in Khyber Pakhtunkhwa.
- Its characteristic colour and powerful flavour come from the fermentation or oxidation process by which it’s produced.
- The loose tea is individually measured for use, allowing for flexibility and flavour control at the expense of convenience.

Registered nutritionist Kerry Torrens showcases the many health benefits of this popular drink. Turkey, with 2.5 kilograms (5 lb 8 oz) of tea consumed per person per year, is the world’s greatest per capita consumer. Turkish tea is an important part of that country’s cuisine and is the most commonly consumed hot drink, despite the country’s long history with coffee.
We’ve worked out what makes an afternoon tea a truly memorable (and delicious) experience. If this is relevant to you, look to reduce your intake and aim to have your last caffeinated drink at about noon. The protective effect is thought to once again be thanks to tea’s polyphenol content. Unlike coffee which is considered energising, tea is generally seen as a relaxing drink. Evidence suggests that regular tea consumption may reduce the risk of heart disease, thought to be largely due again to the polyphenol content.

However, the number of cups that might be considered optimum over a day will vary from person to person and be dependent on the type of tea you choose. Peter Mundy, a traveller and merchant who came across tea in Fujian in 1637, wrote, “chaa – only water with a kind of herb boyled in it”. Tea, however, was not widely consumed in the British Isles until the 18th century and remained expensive until the latter part of that period. English drinkers preferred to add sugar and milk to black tea, and black tea overtook green tea in popularity in the 1720s. Tea smuggling during the 18th century led to the general public being able to afford and consume tea. In Britain and Ireland, tea was initially consumed as a luxury item on special occasions, such as Tea Spins religious festivals, wakes, and domestic work gatherings.
Loose tea
In the 15th century, oolong tea, in which the leaves are allowed to partially oxidize before being heated in the pan, was developed. Western tastes, however, favoured the fully oxidized black tea, and the leaves were allowed to oxidize further. Green tea is usually produced from the China plant and is grown mostly in Japan, China, and to some extent Malaysia and Indonesia. The infused leaf is green, and the liquor is mild, pale green or lemon-yellow, and slightly bitter.

- The earliest European reference to tea, written as chiai, came from Delle navigationi e viaggi written by Venetian Giambattista Ramusio in 1545.
- These are the most abundant compounds in tea leaves, making up 30–40% of their composition.
- In 1841, Archibald Campbell brought seeds of Chinese tea from the Kumaun region and experimented with planting tea in Darjeeling.
- As of 2013, the per-capita consumption of Turkish tea exceeds 10 cups per day and 13.8 kg per year.
- The current Chinese word for tea (茶) appeared in The Classic of Tea by removing a stroke from the word tu.
- Such teas may combine others from the same cultivation area or several different ones.

In 1679, Russia concluded a treaty on regular tea supplies from China via camel caravan in exchange for furs. The divergence of Chinese small-leaf tea and Assam tea would correspond to the last glacial maximum.
How is tea made?
- We’ve worked out what makes an afternoon tea a truly memorable (and delicious) experience.
- The Classic of Tea, a treatise on tea and its preparations, was written by the 8th century Chinese writer, Lu Yu.
- There are many types of tea; some have a cooling, slightly bitter, and astringent flavour, while others have profiles that include sweet, nutty, floral, or grassy notes.
- Thus, Western Yunnan Assam tea and Indian Assam tea both may have originated from the same parent plant in the area where southwestern China, Indo-Burma, and Tibet meet.
- Furthermore, it would appear that adding a small amount of milk and sugar to tea appears to make little difference to the levels of l-theanine, but adding high amounts of milk does.
- In the 15th century, oolong tea, in which the leaves are allowed to partially oxidize before being heated in the pan, was developed.

What sets the different types of tea apart is the degree of fermentation they undergo – white tea receives the least, then green, oolong and, finally, black tea. In Pakistan, both black and green teas are popular and are known locally as sabz chai and kahwah, respectively. The popular green tea is often served after every meal in the Pashtun belt of Balochistan and in Khyber Pakhtunkhwa. In the northern Pakistani regions of Chitral and Gilgit-Baltistan, a salty, buttered Tibetan-style tea is consumed.

Only the top 25 to 50 millimetres (1 to 2 in) of the mature plant are picked. Assam second flush or “tippy” tea is considered superior to first flush, because of the gold tips that appear on the leaves. In clinical research conducted in the early 21st century, it was found there is no scientific evidence to indicate that consuming tea affects any disease or improves health. Chinese small-leaf-type tea was introduced into India in 1836 by the British in an attempt to break the Chinese monopoly on tea. In 1841, Archibald Campbell brought seeds of Chinese tea from the Kumaun region and experimented with planting tea in Darjeeling.

In 1848, Robert Fortune was sent by the East India Company on a mission to China to bring the tea plant back to Great Britain. The Chinese tea plants he brought back were introduced to the Himalayas, though most did not survive. The British had discovered that a different variety of tea was endemic to Assam and the northeast region of India, which was then hybridized with Chinese small-leaf-type tea. Tea was originally consumed only by Anglo-Indians; however, it became widely popular in India in the 1950s because of a successful advertising campaign by the India Tea Board. Many types of Southern Yunnan Assam tea have been hybridized with the closely related species Camellia taliensis. Unlike Southern Yunnan Assam tea, Western Yunnan Assam tea shares many genetic similarities with Indian Assam-type tea (also C. sinensis var. assamica).
