What colour are tea leaves when they are picked
"or ""The Ten Great Chinese Teas"" () are the ten most notable Chinese teas. Below is a list of ten popular teas of China. The highest grades of white tea, yellow tea, and green tea are made from tender tea shoots picked early spring. These young tea shoots may consist of a single terminal bud, a bud with an adjacent leaf or a bud with two adjacent slightly unfurled leaves. It is generally required that the leaves are equal in length or shorter than the buds. The more-oxidized tea—such as red or oolong tea—are made from more mature leaves. For"
"The leaves are long and broad. Fresh leaves contain about 4% caffeine, as well as related compounds including theobromine. The young, light green leaves are preferably harvested for tea production; they have short white hairs on the underside. Older leaves are deeper green. Different leaf ages produce differing tea qualities, since their chemical compositions are different. Usually, the tip (bud) and the first two to three leaves are harvested for processing. This hand picking is repeated every one to two weeks. In 2017 Chinese scientists sequenced the genome of ""Camellia sinensis var. assamica ."" It contains about three billion base"
"tea – Freshly picked leaves only go through heating and drying processes, but do not undergo oxidation. This enables the leaves to keep their original green color and retain most natural substances like polyphenols and chlorophyll contained within the leaves. This kind of tea is produced all over China and is the most popular category of tea. Representative varieties include Dragon Well () and Biluochun from Zhejiang and Jiangsu Provinces respectively. Oolong tea – The tea leaves are partially oxidized, imparting to them the characteristics of both green and black teas. Its taste is more similar to green tea than"
"tea contains several different kinds of antioxidants that provide protection to the membranes of red blood cells. This added protection helps fend off free radical-induced oxidation of the red blood cells. Tea leaves are harvested in the early spring and stored until the late summer when fresh jasmine flowers are in bloom. Jasmine flowers are picked early in the day when the small petals are tightly closed. The flowers are kept cool until nightfall. During the night, jasmine flowers open, releasing their fragrance. This is when the tea scenting takes place. There are two main methods used to scent the"

Each flush has its own particular characteristics. • First Flush Tea Leaves or Spring Tea as it is also commonly called has grayish-greenish hues. • Second flush tea leaves or the summer tea leaves has a purplish-brown shade. • Autumn Teas have blackish-brown hues. • Even: A term used for infused leaves for the uniformity"
"large leaves, typically plucked in the second or third flush with an abundance of tips. Golden flowery includes very young tips or buds (usually golden in colour) that were picked early in the season. Tippy includes an abundance of tips. General Tea leaf grading In the tea industry, tea leaf grading is the process of evaluating products based on the quality and condition of the tea leaves themselves. The highest grades are referred to as ""orange pekoe"", and the lowest as ""fannings"" or ""dust"". Pekoe tea grades are classified into various qualities, each determined by how many of the adjacent"
"the insoluble components are considered, such as the cellulose in the tea leaves. Tea is generally divided into categories based on how it is processed. At least six different types are produced: After picking, the leaves of ""C. sinensis"" soon begin to wilt and oxidize unless immediately dried. An enzymatic oxidation process triggered by the plant's intracellular enzymes causes the leaves to turn progressively darker as their chlorophyll breaks down and tannins are released. This darkening is stopped at a predetermined stage by heating, which deactivates the enzymes responsible. In the production of black teas, halting by heating is carried"
"in late April to early May. The second harvest usually takes place from June through July, and the third picking takes place in late July to early August. Sometimes, there will also be a fourth harvest. It is the first flush in the spring that brings the best-quality leaves, with higher prices to match. Green tea is processed using either artisanal or modern methods. Sun-drying, basket or charcoal firing, or pan-firing are common artisanal methods. Oven-drying, tumbling, or steaming are common modern methods. Processed green teas, known as ""aracha"", are stored under low humidity refrigeration in 30- or 60-kg paper"
"The second flush, harvested later, is the more prized ""tippy tea"", named thus for the gold tips that appear on the leaves. This second flush, tippy tea, is sweeter and more full-bodied and is generally considered superior to the first flush tea. The leaves of the Assam tea bush are dark green and glossy and fairly wide compared to those of the Chinese tea plant. The bush produces delicate white blossoms. Assam tea Assam tea is a black tea named after the region of its production, Assam, in India. Assam tea is manufactured specifically from the plant ""Camellia sinensis"" var."
"in the browning of the leaves and intensification of their flavor compounds. From the moment they are plucked, the cells within the tea leaves are exposed to oxygen and the volatile compounds within them begin to undergo chemical reactions. It is at this stage that polyphenolic oxidase, including theaflavin and thearubigin, begin to develop within the leaves. Theaflavins lend briskness and brightness to the tea while thearubigins offer depth and fullness to the liquor that’s produced.In order to bring out specific intensities in flavors, tea makers control the amount of oxidation the leaves undergo. Controlled-oxidation is typically carried out in"
"by the largest leaves; China type, characterised by the smallest leaves; and Cambodian type, characterised by leaves of intermediate size. The Cambod type tea (""C. assamica"" subsp. ""lasiocaly"") was originally considered a type of assam tea. However, later genetic work showed that it is a hybrid between Chinese small leaf tea and assam type tea. Darjeeling tea also appears to be hybrids between Chinese small leaf tea and assam type tea. A tea plant will grow into a tree of up to if left undisturbed, but cultivated plants are generally pruned to waist height for ease of plucking. Also, the"
"than 1,000. Some of the variations are due to different strains of the Camillia plant. The popular Tieguanyin, for example, is traced back to a single plant discovered in Anxi in Fujian province. Other teas draw some of their characteristics from local growing conditions. However, the largest factor in the wide variations comes from differences in tea processing after the tea leaves are harvested. White and green teas are heat-treated () soon after picking to prevent oxidization, often called fermentation, caused by natural enzymes in the leaves. Oolong teas are partially oxidized. Black teas are fully oxidized. Other differences come"
"teas tend to retain most of their green color and vegetal characteristics due to a lower production of polyphenols. A semi-oxidized leaf has a brown appearance and produces yellow-amber liquor. In a fully oxidized tea, amino acids and lipids break down completely, turning the leaves blackish-brown. The flavors in such a tea are more brisk and imposing. Rolling involves shaping the processed leaves into a tight form. As a part of this procedure, wilted/fixed leaves are gently rolled, and depending on the style, they are shaped to look wiry, kneaded, or as tightly rolled pellets. During the rolling action, essential"
"of Darjeeling tea has a delicate aroma and brews to a pale golden colour with a mellow taste and a hint of sweetness. Darjeeling white tea leaves are very fluffy and light; therefore, it is recommended to use more (by volume) when preparing it than one normally would for other teas. The tea is hand-picked and rolled, then withered in the sun, making it a rare tea. It is grown in the rainy and cold climate of Darjeeling at altitudes up to 2000 metres. Darjeeling oolong is lighter than usual Darjeeling black tea during first flush, as it is semioxidized."
"substances such as caffeine, anthocyanin and tea polyphenol are increased. Therefore, the taste of summer tea is slightly bitter, and the aroma is not as strong as that of spring tea. The leaves are relatively large and wide. But summer tea is resistant to foam and the price is cheap. Autumn tea The tea that was harvested after August is called autumn tea, also called white dew tea. In autumn, the tea trees are harvested in spring and summer. The newly grown leaves contain relatively less material, yellowish leaves, different sizes, and the taste and aroma are relatively dull. Bailu"
"of environmental contaminants released and consumed. All tea leaves contain fluoride; however, mature leaves contain as much as 10 to 20 times the fluoride levels of young leaves from the same plant. The fluoride content of a tea leaf depends on the leaf picking method used and the fluoride content of the soil from which it has been grown; tea plants absorb this element at a greater rate than other plants. Care in the choice of the location where the plant is grown may reduce the risk. It is speculated that hand-picked tea would contain less fluoride than machine-harvested tea,"
"fired before drying. Most definitions agree, however, that white tea is not rolled or oxidized, resulting in a flavour characterized as ""lighter"" than most green or traditional black teas. In spite of its name, brewed white tea is pale yellow. Its name derives from the fine silvery-white hairs on the unopened buds of the tea plant, which give the plant a whitish appearance. The unopened buds are used for some types of white tea. It is harvested primarily in China, mostly in the Fujian province, but more recently produced in Eastern Nepal, Taiwan, Thailand, Galle (Southern Sri Lanka) and northeast"
"tea flower in September/October whereas coastal tea flowers in May/June. There are two methods of processing honeybush for use in tea. In the traditional method, the leaves of the bush are harvested, cut and bruised (often with mechanical rollers), and then left in the sun to oxidise. The modern, industralised process oxidises the leaves in rotating, heated tanks at temperatures of 70–90 °C, for two to three days. The leaves are then air-dried. Afterwards, the leaves are sifted and graded according to the application: Honeybush is low in tannin (0.45%). Some of the bioactive compounds present in honeybush include: ""Cyclopia"""
"are picked in the early Spring before China's Qingming Festival. When picking the tea, only the new tea buds and the leaf next to the bud are picked. It is said by local tea farmers that the leaves resemble orchid buds. Huangshan Maofeng Huangshan Maofeng tea (; pronounced ) is a green tea produced in south eastern interior Anhui province of China. The tea is one of the most famous teas in China and can almost always be found on the China Famous Tea list. The tea is grown near huangshan (Yellow Mountain), which is home to many famous varieties"
"body than the latter style, which is generally lighter with shorter oxidation. The character of the tea tree leaves of the former allows for the extended piled-up time without turning bad. Both styles have their own group of followers, as taste is a rather personal preference. As with all white teas, it is best prepared with water below boiling (at around 75 to 80 degrees Celsius or 167 to 176 degrees Fahrenheit) and produces a slightly viscous glittering pale yellow color with evidence of floating white hairs that reflect light. Baihao Yinzhen is said to smell of ""fresh-cut hay"", and"
"the high-quality Benshan Maojian tea, which was officially named “Xinyang Maojian”. Xinyang Maojian is known for its unique and delicious flavor. The color is yellowish especially when boiled with water. The tea liquor is slightly thick and tastes refreshingly brisk and with a long-lasting aftertaste. The tea leaves, which are covered in abundant white hairs, are thin, tender and evenly shaped. The leaves are commonly known as ""hairy tips”, a name that refers to their slightly dark-green color, straight and delicate edges, and thin and firmly rolled appearance with both ends in a pointed shape. The regular length of a"
"tea estates to minimize the costs and time between plucking and tea processing. The tea leaves are taken to the upper floors of the factories where they are spread in troughs, a process known as withering, which removes excess weight in the leaf. Once withered, the tea leaves are rolled, twisted and parted, which serves as a catalyst for the enzymes in the leaves to react with the oxygen in the air, especially with the production of black tea. The leaves are rolled on circular brass or wooden battened tables and are placed in a rotating open cylinder from above."
"Canadian Food Inspection Agency (CFIA). It is one of the foods for which a standard of identity is specified according to the Food and Drug Regulations. It should contain not less than 33% water-soluble extractive (determined by official method FO-37 which is the determination of water-soluble extractive in tea) and the total ash should between 4% to 7%. Green tea Green tea is a type of tea that is made from ""Camellia sinensis"" leaves that have not undergone the same withering and oxidation process used to make oolong teas and black teas. Green tea originated in China, but its production"
"average temperature is low, which is conducive to the synthesis and accumulation of nitrogenous compounds such as amino acids and caffeine. The harvest season for Maojian tea is in spring and fall. However, the best quality tea comes from leaves that are harvested in mid-April. Chinese call it ""Yu Qian Tea"", which means the tea is picked earlier in the spring before the solar term 'Grain Rain' (Guyu). Because the leaves are rare and fresh, the price is two or three times higher than tea produced after this season. In general, the approximate ratio of fresh leaves to produced tea"
"of black and green tea respectively. Steaming tea leaves was the primary process used for centuries in the preparation of tea. After the transition from compressed tea, 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 rather than steamed. This is the origin of today's loose teas and the practice of brewed tea. After cutting, tea is subjected to a so-called ""fermentation."" This process is not actually a fermentation, which is an anaerobic process, but rather an enzymatic oxidization of"
"from the main characteristics of oolong tea. Darjeeling oolong teas are made from finely plucked leaves, usually two leaves and a bud, and are sometimes withered naturally in sun and air. The withered leaves get hand-rolled and pan-fired at certain temperatures. This can also be done in machine: withered in trough, lightly rolled in a rolling machine and fired at 220 °C in a quality dryer with faster run-through, depending on the leaves used. A green tea variant is produced by several estates in Darjeeling. Green tea is not fermented, but is steamed to stop oxidation starting, which preserves most"
"classified into various types based on several different factors. The most common is the flush, or the time of the year when the leaves are plucked (and thus also by leaf size). The mode of preparation also differs: Leaf teas are processed either by roasting or steaming. Southern, warmer regions such as Boseong in South Jeolla Province, Hadong in South Gyeongsang Province, and Jeju Island are famous for producing high quality tea leaves. Green tea can be blended with other ingredients. In Canada, green tea is defined as a dry-based mixture and the sale of it is regulated by the"
"picked; tea picked earlier in the season, such as the first buds picked in early April, will be steeped at lower temperature () than tea leaves picked in June (). Once the water is at the right temperature, the host will pour the water into the pot and steep it for anywhere from 20 seconds to two to three minutes, depending on the tea. After steeping is complete, the host pours the tea into the decanting bowl, which serves to get the water off the leaves in the pot and also to give the tea an even mixture. Then it"
"short plants bear more new shoots which provide new and tender leaves and increase the quality of the tea. Only the top 1–2 inches of the mature plant are picked. These buds and leaves are called 'flushes'. A plant will grow a new flush every seven to 15 days during the growing season. Leaves that are slow in development tend to produce better-flavoured teas. Pests of tea include mosquito bugs of the genus ""Helopeltis"" (which are true bugs that must not be confused with the dipteran) that can tatter leaves, so they may be sprayed with insecticides. In addition, there"

These leaves, after being roasted, can be ground up or crumpled, then brewed or steeped in hot water in a form similar to tea. The resulting beverage is similar in taste to green tea, but with less caffeine content than either regular tea or coffee. Coffee leaves closely resemble the leaves and stalks of Paraguay tea (""Ilex paraguariensis""). In some regions, such as Sumatra and Ethiopia, only the leaves are taken from the"
"Black tea Black tea is a type of tea that is more oxidized than oolong, green, and white teas. Black tea is generally stronger in flavour than the less oxidized teas. All four types are made from leaves of the shrub (or small tree) ""Camellia sinensis."" Two principal varieties of the species are used – the small-leaved Chinese variety plant (""C. sinensis"" var. ""sinensis""), used for most other types of teas, and the large-leaved Assamese plant (""C. sinensis"" var. ""assamica""), which was traditionally mainly used for black tea, although in recent years some green and white teas have been produced."
"Tea Museum and hosting the annual Penghong Tea Industry and Culture Festival. The tea bushes are planted on the leeward side of hills in areas with sufficient humidity and sunshine. The tea is only harvested in the middle of summer, only about 40–50% of the leaves can be used, and the harvest is susceptible to drought. Therefore, the annual yield is low and the price is relatively high. After being harvested from young leaves and tips in the summer, the tea is heavily oxidized (around 70%), approaching the level of black tea. Unlike other oolongs which typically make use of"

The leaves go through a series of drying processes where first they are laid out for twelve to eighteen hours to wither, then the oxidation process for a little under an hour, and finally they are baked to remove the rest of the moisture. The excess sticks and fibers are removed and the tea is packaged. The tea is harvested from May to October. The plantation packages American Classic Tea and Charleston Tea Plantation tea.
