Silver Needle
Baihao Yinzhen (; pronounced ), also known as White Hair Silver Needle, is a white tea produced in Fujian Province in China. Silver Needle or Bai Hao Yin Zhen or usually just Yin Zhen is the Chinese type of white tea. Amongst white teas, this is the most expensive variety and the most prized, as only top buds ( leaf shoot) of the camellia sinensis plant are used to produce the tea.陳宗懋，中國茶經，pp 236，上海文化出版社，1992 Genuine Silver Needles are made from cultivars of the ''Da Bai'' (Large White) tea tree family. There are other productions that look similar with downy leaf shoots but most are green teas, and as green teas, they taste differently and have a different biochemical potency than the genuine white tea Silver Needle.袁弟順，中國白茶，廈門大學出版社，2006 It is commonly included among China's famous teas. Possible origins In the early years of Jiaqing in the Qing Dynasty (AD 1796), Baihao Yinzhen was successfully cultivated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Tea
White tea may refer to one of several styles of tea which generally feature young or minimally processed leaves of the ''Camellia sinensis'' plant. Currently there is no generally accepted definition of white tea and very little international agreement; some sources use the term to refer to tea that is merely dried with no additional processing, some to tea made from the buds and immature tea leaves picked shortly before the buds have fully opened and allowed to wither and dry in natural sun, while others include tea buds and very young leaves which have been steamed or fired before drying. Most definitions agree, however, that white tea is not rolled or oxidized, resulting in a flavor characterized as "lighter" than most green or traditional black teas. In spite of its name, sweet, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enzyme
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts are catalytic RNA molecules, called ribozymes. Enzymes' specificity comes from their unique three-dimensional structures. Like all catalysts, enzymes increase the reaction ra ...

Darjeeling Tea (white)
Darjeeling tea is a tea made from ''Camellia sinensis var. sinensis'' that is grown and processed in Darjeeling or Kalimpong Districts in West Bengal, India. Since 2004, the term ''Darjeeling tea'' has been a registered geographical indication referring to products produced on certain estates within Darjeeling and Kalimpong. The tea leaves are processed as black tea, though some estates have expanded their product offerings to include leaves suitable for making green, white and oolong teas. The tea leaves are harvested by plucking the plant's top two leaves and the bud, from March to November, a time span that is divided into four flushes. The first flush consists of the first few leaves grown after the plant's winter dormancy and produce a light floral tea with a slight astringency; this flush is also suitable for producing a white tea. Second flush leaves are harvested after the plant has been attacked by a leafhopper and the camellia tortrix so that the leaves create a tea w ...

Ceylon Tea (white)
Sri Lanka (formerly called Ceylon) has a climate and varied elevation that allows for the production of both ''Camellia sinensis var. assamica'' and ''Camellia sinensis var. sinensis'', with the assamica varietal holding the majority of production. Tea production is one of the main sources of foreign exchange for Sri Lanka, and accounts for 2% of GDP, contributing over US$1.3 billion in 2021 to the economy of Sri Lanka. It employs, directly or indirectly, over 1 million people, and in 1995 directly employed 215,338 on tea plantations and estates. In addition, tea planting by smallholders is the source of employment for thousands whilst it is also the main form of livelihood for tens of thousands of families. Sri Lanka is the world's fourth-largest producer of tea. In 1995, it was the world's leading exporter of tea (rather than producer), with 23% of the total world export, and Sri Lanka ranked second on tea export earnings in 2020 after China. The highest production of 340 milli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shoumei Tea
Shoumei (; Standard Chinese pronunciation ) is a white tea that is produced from naturally withered upper leaf and tips, with a stronger flavor reminiscent of lighter oolong teas. It is mostly grown in Fujian Province and Guangxi Province in China. Because it is plucked later than Bai Mudan, the tea may be darker in color, but it should still have a proportionate green color. Some lower grades of Shou Mei may be golden in color with many black and red leaves, making a darker brew with more depth. Technically this tea, being a fourth-grade tea, is a by-product of Baihao Yinzhen tea production and uses ''Da Bai'' or Large White leaves. __TOC__ Tasting and brewing The tea can be brewed very differently and there are many combinations that yield interesting results, but it is important to use good mineral water to bring out the sweetness and aroma of the tea and not to over brew or make a bitter and very strong brew. Typically, white teas are brewed at a lower temperature than b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bai Mu Dan Tea
Bai Mudan () is a type of white tea made from plucks each with one leaf shoot and two immediate young leaves (one bud two leaf ratio) of the ''Camellia sinensis'' plant.陳宗懋, 中國茶經, pp 236 上海文化出版社 Bai Mudan is sometimes preferred by white tea drinkers for its fuller flavor and greater potency than the other major type of white tea, Bai Hao Yinzhen. The latter is made purely with leaf shoots, and so it is comparatively softer and more subtle. The typical taste of Bai Mudan is a result of both the processing and the tea plant cultivars employed in the production. __TOC__ Production and processing The family of tea cultivars used in producing Bai Mudan are the "Dai Bai" varieties. In eastern Fujian, the cultivar Fuding Dai Bai is used. In northern Fujian, the Zhenghe Dai Bai cultivar is used. The differences in the plant yield two distinct styles of Bai Mudan: the Fuding variety and the Zhenghe variety. Genuine Bai Mudan is a white tea; therefore, it is ...

Viscous
The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity quantifies the internal frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced through a tube, it flows more quickly near the tube's axis than near its walls. Experiments show that some stress (such as a pressure difference between the two ends of the tube) is needed to sustain the flow. This is because a force is required to overcome the friction between the layers of the fluid which are in relative motion. For a tube with a constant rate of flow, the strength of the compensating force is proportional to the fluid's viscosity. In general, viscosity depends on a fluid's state, such as its temperature, pressure, and rate of deformation. However, the dependence on some of these properties is n ...

Fahrenheit
The Fahrenheit scale () is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit (1686–1736). It uses the degree Fahrenheit (symbol: °F) as the unit. Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from a mixture of water, ice, and ammonium chloride (a salt). The other limit established was his best estimate of the average human body temperature, originally set at 90 °F, then 96 °F (about 2.6 °F less than the modern value due to a later redefinition of the scale). For much of the 20th century, the Fahrenheit scale was defined by two fixed points with a 180 °F separation: the temperature at which pure water freezes was defined as 32 °F and the boiling point of water was defined to be 212 °F, both at sea level and under standard atmospheric pressure. ...

Celsius
The degree Celsius is the unit of temperature on the Celsius scale (originally known as the centigrade scale outside Sweden), one of two temperature scales used in the International System of Units (SI), the other being the Kelvin scale. The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale or a unit to indicate a difference or range between two temperatures. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale in 1742. Before being renamed in 1948 to honour Anders Celsius, the unit was called ''centigrade'', from the Latin ''centum'', which means 100, and ''gradus'', which means steps. Most major countries use this scale; the other major scale, Fahrenheit, is still used in the United States, some island territories, and Liberia. The Kelvin scale is of use in the sciences, with representing absolute zero. Since 1743 the Celsius scale has been based on 0 °C for the freezing ...
