Oolong (, ; Chinese: 烏龍茶 is a traditional semi-oxidized Chinese tea produced through a process that includes withering the leaves under strong sun and allowing some oxidation to occur before curling and twisting. Most oolong teas, especially those of fine quality, involve unique tea plant cultivars that are exclusively used for particular varieties. The degree of oxidation, which is controlled by the length of time between picking and final drying, can range from 8% to 85% depending on the variety and production style. Oolong is especially popular in southeastern China and among ethnic Chinese in Southeast Asia, as is the Fujian preparation process known as the gongfu tea ceremony.
Gyokuro is a type of shaded green tea from Japan. It differs from the standard sencha in being grown under the shade rather than the full sun. The name "gyokuro" translates as "jewel dew". While most sencha is from the Yabukita (薮北) cultivar of Camellia sinensis, gyokuro is often made from a specialized variety such as Asahi, Okumidori, Yamakai, and Saemidori.
Hōjicha is a Japanese green tea. It is distinctive from other Japanese green teas because it is roasted in a porcelain pot over charcoal. It is roasted at 150 °C (302 °F) to prevent oxidation and produce a light golden colour, as opposed to other Japanese teas which are steamed. In general, the base of a hōjicha consists of leaves from the second harvest or after.
Yellow tea can refer to Chinese huángchá and Korean hwangcha.
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.
Kamairicha (釜炒り茶) is a Japanese green tea produced by pan-roasting or pan-firing tea leaves during the early stages of production. It is most commonly produced in the western region of Japan. Kamairicha has a mildly roasted flavour with more sweet and fresh notes than bitter ones.
Kukicha (茎茶), or twig tea, also known as bōcha (棒茶), is a Japanese tea blend made of stems, stalks, and twigs. It is available as a green tea or in more oxidised processing. Kukicha has a unique flavour and aroma among teas, due to its being composed of parts of the plant that are excluded from most other teas.
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.
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. 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.
Epigallocatechin gallate (EGCG), also known as epigallocatechin-3-gallate, is the ester of epigallocatechin and gallic acid, and is a type of catechin.
Matcha (抹茶) ; is a finely ground powder of specially grown and processed green tea leaves that originated in China and developed in Japan. It is mostly produced in Japan 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 and developed in Japan thereafter.
Sencha is a type of Japanese ryokucha which is prepared by infusing the processed whole tea leaves in hot water. This is as opposed to matcha, powdered Japanese green tea, where the green tea powder is mixed with hot water and therefore the leaf itself is included in the beverage. Sencha is the most popular tea in Japan.
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.
Uji tea is a common name for all Japanese green tea produced from Uji, Kyoto. The three main types of Uji tea are Matcha, Sencha and Gyokuro. Japanese tea is originated from the Tang dynasty of China, which is during the Heian period of Japan when Chinese influences were at its peak. When tea seeds were introduced to Japan, they were first planted at Toganoo. These seeds were later spread in Uji, which became the site to produce the highest quality of tea leaf in Japan.
Black tea is a type of tea that is more oxidized than oolong, yellow, white and green teas. Black tea is generally stronger in flavour than other teas. All five types are made from leaves of the shrub Camellia sinensis, though Camellia taliensis is also used rarely.
Ujeon, also called cheonmul-cha, refers to nokcha made of young, tender leaves and buds hand-plucked before gogu. The delicate tea has sweet, soft, and subtle flavor profile, and is best steeped at a temperature of 50 °C (122 °F).
Kabuse tea, or kabusecha (かぶせ茶) is a class of Japanese tea leaf. Kabuseru (かぶせる) literally means to cover or place on top, as a hat on a head, therefore kabuse tea is a tea leaf harvested from a tea plant that, for some period of time ranging from 2–25 days, has had a porous material draped over the plant while the young leaves are being produced. Kabuse tea is almost exclusively a first flush tea. Though kabuse tea is usually processed into a green tea after picking, kabuse tea denotes a pre-picking process and the freshly picked leaf can be used to produce any kind of tea, from green tea to oolong tea to black tea, or other types.
Tea is an important part of Japanese culture. It first appeared in the Nara period (710–794), introduced to the archipelago by ambassadors returning from China, but its real development came later, from the end of the 12th century, when its consumption spread to Zen temples, also following China's example; it was then powdered tea that was drunk after being beaten. In the Middle Ages, tea became a common drink for the elite, and in the 16th century, the art of the "tea ceremony" was formalized. It is now one of the most emblematic elements of Japanese culture, whose influence extends beyond the simple context of tea drinking. Tea-growing developed in the pre-modern era, particularly during the Edo period (1603–1868), when tea became a popular beverage consumed by all strata of society. New ways of processing and consuming tea leaves were developed, starting with sencha, a steamed oxidation-stopped brew that became the most common.
