Compressed tea,called tea bricks,tea cakes or tea lumps,and tea nuggets according to the shape and size,are blocks of whole or finely ground black tea,green tea,or post-fermented tea leaves that have been packed in molds and pressed into block form. This was the most commonly produced and used form of tea in ancient China prior to the Ming Dynasty. Although tea bricks are less commonly produced in modern times,many post-fermented teas,such as pu-erh ,are still commonly found in bricks,discs,and other pressed forms. Tea bricks can be made into beverages like tea or eaten as food,and were also used in the past as a form of currency.
In ancient China,compressed teas were usually made with thoroughly dried and ground tea leaves that were pressed into various bricks or other shapes,although partially dried and whole leaves were also used. Some tea bricks were also mixed with binding agents such as flour,blood,or manure to better preserve their form so they could withstand physical use as currency. [1] Newly formed tea bricks were then left to cure,dry,and age prior to being sold or traded. Tea bricks were preferred in Asian trade prior to the 19th century,since they were more compact and less susceptible to physical damage than loose leaf tea. This was important during transportation over land by caravans on the Tea Horse Road.
Tea bricks are still currently manufactured for drinking,as in pu-erh teas,as well as for souvenirs and novelty items,though most compressed teas produced in modern times are usually made from whole leaves. The compressed tea can take various traditional forms,many of them still being produced. A dome-shaped nugget of 100g (standard size) is simply called tuóchá (沱茶),which is translated several ways,sometimes as "bird's nest tea" or "bowl tea". A small dome-shaped nugget with a dimple underneath just enough to make one pot or cup of tea is called a xiǎo tuóchá ( 小 沱 茶 ;the first word meaning "small") which usually weighs 3g–5g. A larger piece around 357g,which may be a disc with a dimple,is called bǐngchá (饼茶,literally "biscuit tea" or "cake tea"). A large,flat,square brick is called fāngchá (方茶,literally "square tea").
To produce a tea brick,ground or whole tea is first steamed,then placed into one of a number of types of press and compressed into a solid form. Such presses may leave an intended imprint on the tea,such as an artistic design or simply the pattern of the cloth with which the tea was pressed. Many powdered tea bricks are moistened with rice water in pressing to assure that the tea powder sticks together. The pressed blocks of tea are then left to dry in storage until a suitable degree of moisture has evaporated.
Although the Chinese regard it as an inferior product, [tea bricks are] greatly esteemed by the Tibetans for [their] powerful flavor, which harmonizes particularly well with that of the rancid yak's butter which they mix with their tea. Brick tea comprises not only what we call tea leaves, but also the coarser leaves and some of the twigs of the shrub, as well as the leaves and fruit of other plants and trees (the alder, for instance). This amalgam is steamed, weighed, and compressed into hard bricks, which are packed up in coarse matting in subunits of four. These rectangular parcels weigh between twenty-two and twenty-six pounds—the quality of the tea makes a slight difference to the weight—and are carried to Kangting by coolies. [2]
The brick tea is packaged [in Kangting] either in the courtyard or in the street outside, and it is quite a complicated process. When the coolies bring it in from Ya'an, it has to be repacked before being consigned upcountry, for in a coolie's load the standard subunit is four bricks lashed together, and these would be the wrong shape for animal transport. So they are first cut in two, then put together in lots of three, leaving what they call a gam, which is half a yak's load. Tea which is going to be consumed reasonably soon is done up in a loose case of matting, but the gams, which are bound for remote destinations, perhaps even for Lhasa, are sewn up in yakhides. [3]
— André Migot, Tibetan Marches
Due to their density and toughness tea bricks were consumed after they were broken into small pieces and boiled. Traditionally, in the Tang Dynasty, they were consumed being ground to a fine powder. The legacy of using tea bricks in powdered form can be seen in modern Japanese matcha tea powders as well as the pulverized tea leaves used in the lei cha (擂茶) eaten by the Hakka people and some people in Hunan province.
In ancient China the use of tea bricks involved three separate steps:
In modern times bricks of pu-erh type teas are flaked, chipped, or broken and directly steeped after thorough rinsing; the process of toasting, grinding, and whisking to make tea from tea bricks has become uncommon.
Tteokcha (떡차;lit. "cake tea"), also called byeongcha (병차;餠茶;lit. "cake tea"), was the most commonly produced and consumed type of tea in pre-modern Korea. [4] [5] [6] Pressed tea made into the shape of yeopjeon , the coins with holes, was called doncha (돈차;lit. "money tea"), jeoncha (전차;錢茶;lit. "money tea"), or cheongtaejeon (청태전;靑苔錢;lit. "green moss coin"). [7] [8] [9] Borim-cha (보림차;寶林茶) or Borim-baengmo-cha (보림백모차;寶林白茅茶), named after its birthplace, the Borim temple in Jangheung, South Jeolla Province, is a popular tteokcha variety. [10]
Tea bricks are used as a form of food in parts of Central Asia and Tibet in the past as much as in modern times. In Tibet pieces of tea are broken from tea bricks, and boiled overnight in water, sometimes with salt. The resulting concentrated tea infusion is then mixed with butter, cream or milk and a little salt to make butter tea, a staple of Tibetan cuisine. [1]
The tea mixed with tsampa is called Pah. Individual portions of the mixture are kneaded in a small bowl, formed into balls and eaten. Some cities of the Fukui prefecture in Japan have food similar to tsampa, where concentrated tea is mixed with grain flour. However, the tea may or may not be made of tea bricks.
In parts of Mongolia and central Asia, a mixture of ground tea bricks, grain flours and boiling water is eaten directly. It has been suggested[ by whom? ] that tea eaten whole provides needed roughage normally lacking in the diet.
Due to the high value of tea in many parts of Asia, tea bricks were used as a form of currency throughout China, Tibet, Mongolia, and Central Asia. This is quite similar to the use of salt bricks as currency in parts of Africa. Tea bricks were in fact the preferred form of currency over metallic coins for the nomads of Mongolia and Siberia. The tea could not only be used as money and eaten as food in times of hunger but also brewed as allegedly beneficial medicine for treating coughs and colds. Until World War II, tea bricks were still used as a form of edible currency in Siberia. [1]
Tea bricks for Tibet were mainly produced in the area of Ya'an (formerly Yachou-fu) in Sichuan province. The bricks were produced in five different qualities and valued accordingly. The kind of brick which was most commonly used as currency in the late 19th and early 20th century was that of the third quality which the Tibetans called "brgyad pa" ("eighth"), because at one time it was worth eight Tibetan tangkas (standard silver coin of Tibet which weighs about 5.4 grams) in Lhasa. Bricks of this standard were also exported by Tibet to Bhutan and Ladakh. [11]
All tea plant tissues accumulate fluorine to some extent. Tea bricks that are made from old tea leaves and stems can accumulate large amounts of this element, which can make them unsafe for consumption in large quantities or over prolonged periods. Use of such teas has led to fluorosis, a form of fluoride poisoning that affects the bones and teeth, in areas of high brick tea consumption such as Tibet. [12]
Tea is an aromatic beverage prepared by pouring hot or boiling water over cured or fresh leaves of Camellia sinensis, an evergreen shrub native to East Asia which probably originated in the borderlands of southwestern China and northern Myanmar. Tea is also made, but rarely, from the leaves of Camellia taliensis. After plain water, tea is the most widely consumed drink in the world. There are many different types of tea; some have a cooling, slightly bitter, and astringent flavour, while others have profiles that include sweet, nutty, floral, or grassy notes. Tea has a stimulating effect in humans, primarily due to its caffeine content.
Green tea is a type of tea that is made from Camellia sinensis leaves and buds that have not undergone the same withering and oxidation process which is used to make oolong teas and black teas. Green tea originated in China, and since then its production and manufacture has spread to other countries in East Asia.
Chinese tea culture includes all facets of tea found in Chinese culture throughout history. Physically, it consists of tea cultivation, brewing, serving, consumption, arts, and ceremonial aspects. Tea culture is an integral part of traditional Chinese material culture and spiritual culture. Tea culture emerged in the Tang dynasty, and flourished in the succeeding eras as a major cultural practice and as a major export good.
Pu'er or pu-erh is a variety of fermented tea traditionally produced in Yunnan Province, China. In the context of traditional Chinese tea production terminology, fermentation refers to microbial fermentation, and is typically applied after the tea leaves have been sufficiently dried and rolled. As the tea undergoes controlled microbial fermentation, it also continues to oxidize, which is also controlled, until the desired flavors are reached. This process produces tea known as hēichá (黑茶), literally "black tea", though the term is commonly translated to English as "dark tea" to distinguish it from the English-language black tea, for which it is not.
Tsampa or Tsamba is a Tibetan and Himalayan staple foodstuff, it is also prominent in parts of northern Nepal. It is a glutinous meal made from roasted flour, usually barley flour and sometimes also wheat flour and flour prepared from tree peony seeds. It is usually mixed with the Tibetan butter tea. It is also eaten in Turkestan and Mongolia, where it is known as zamba.
Chinese teas can be classified into six distinctive categories: white, green, yellow, oolong, black and post-fermented. Others add categories for scented and compressed teas. All of these come from varieties of the Camellia sinensis plant. Most Chinese teas are cultivated and consumed in China. It is commonly available in Chinese restaurants and grocery shops worldwide. Green tea is the most common type of tea consumed in China.
Ya'an is a prefecture-level city in the western part of Sichuan province, China, located just below the Tibetan Plateau. The city is home to Sichuan Agricultural University, the only 211 Project university and the largest regional comprehensive university in Ya'an. As of the 2020 Chinese census, Ya'an has a population of 1,434,603.
Dianhong tea is a type of relatively high-end, gourmet Chinese red tea sometimes used in various tea blends and grown in Yunnan Province, China. The main difference between Dianhong and other Chinese red teas is the amount of fine leaf buds, or "golden tips," present in the dried tea. Dianhong tea produces a brew that is brassy golden orange in colour with a sweet, gentle aroma and no astringency. Cheaper varieties of Dianhong produce a darker brownish brew that can be very bitter.
Tibet developed a distinct culture due to its geographic and climatic conditions. While influenced by neighboring cultures from China, India, and Nepal, the Himalayan region's remoteness and inaccessibility have preserved distinct local influences, and stimulated the development of its distinct culture.
Butter tea, also known as Bho jha, cha süma and Su Chya in the Sherpa language, is a drink of the people in the Himalayan regions of Nepal, Bhutan, India, Pakistan especially in Khyber Pakhtunkhwa and Gilgit-Baltistan, Afghanistan, Kazakhstan, Tajikistan, East Turkestan, Tibet and western regions of modern-day China and Central Asia. Traditionally, it is made from tea leaves, yak butter, water, and salt, although butter made from cow's milk is increasingly used, given its wider availability and lower cost.
The history of tea in Japan began as early as the 8th century, when the first known references were made in Japanese records. 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 Buddhist monks Kūkai and Saichō may have been the first to bring tea seeds to Japan. The first form of tea brought from China was probably brick tea. Tea became a drink of the royal classes when Emperor Saga encouraged the growth of tea plants. Seeds were imported from China, and cultivation in Japan began.
Tibetan cuisine includes the culinary traditions and practices of the Tibetan people in the Tibet region. The cuisine reflects the Tibetan landscape of mountains and plateaus and includes influences from neighbors. It is known for its use of noodles, goat, yak, mutton, dumplings, cheese, butter, yogurt, and soups. Vegetarianism has been debated by religious practitioners since the 11th century but is not prevalent due to the difficulty of growing vegetables, and cultural traditions promoting consumption of meat.
Korean tea is a beverage consisting of boiled water infused with leaves, roots, flowers, fruits, grains, edible mushrooms, or seaweed. It may or may not contain tea leaves.
Fermented tea is a class of tea that has undergone microbial fermentation, from several months to many years. The exposure of the tea leaves to humidity and oxygen during the process also causes endo-oxidation and exo-oxidation. The tea leaves and the liquor made from them become darker with oxidation. Thus, the various kinds of fermented teas produced across China are also referred to as dark tea, not be confused with black tea, which is actually referred to as "red tea" in Chinese. The most famous fermented tea is pu'er produced in Yunnan province.
Tea processing is the method in which the leaves from the tea plant Camellia sinensis are transformed into the dried leaves for brewing tea.
The use of historical money in Tibet started in ancient times, when Tibet had no coined currency of its own. Bartering was common, gold was a medium of exchange, and shell money and stone beads were used for very small purchases. A few coins from other countries were also occasionally in use.
Tibetan tea is a post-fermented tea that originated in Yaan. It has been long been traded as a tea brick between China and Tibet. The tea is packed in Kangting and shipped over the caravan routes by yak.
Matcha (抹茶) is a finely ground powder of specially grown and processed green tea leaves that originated in China. Later, the characteristic green color of modern matcha was developed in Japan, where most matcha is produced today. In the 12th century at the latest, Chinese compressed tea, the raw material for matcha, was introduced to Japan. When the production of compressed tea was banned in China in 1391, matcha was abandoned in China but continued to develop in Japan thereafter.
Doncha, also called jeoncha, is a coin-shaped post-fermented tea produced in Korea. The tea has been called cheongtae-jeon in the Jangheung region in South Jeolla Province.
Dian cha, is a method of preparing and drinking tea in Sinosphere includes China, Japan, and Vietnam. It later evolved into the Japanese tea ceremony using matcha.
