That is, the human sense of smell is used to distinguish whether black tea has smoke, sour, stale, musty, sun-dried and other odors. The dry tea of high-quality black tea has a sweet fragrance, and will have a sweet and pleasant aroma after brewing, while
First, feel the weight, tightness and thickness of the black tea cords with your hands. The cords of high-quality black tea are relatively tight, and the one that is heavy is better, and the one that is rough and light is worse. The main purpose of touchi

Qimen black tea, or Qihong for short, is a treasure of traditional Chinese Kung Fu black tea. It is a famous tea in history. It was produced in the late 19th century and is one of the world’s three high-flavor teas. "Prince Tea" and other
Lapsang Souchong black tea entered Europe in 1610. In 1662, when Princess Catherine of Portugal married King Charles II, her dowry contained boxes of Chinese Lapsang Souchong black tea. Since then, black tea was brought to the British court, and drinking
The originator of black tea is in China. The earliest black tea in the world was invented by tea farmers in the Wuyishan tea area in Fujian during the Ming Dynasty in China, and it was named " Lapsang souchong". The Jiang family in Tongmu Villag
This technology mainly addresses the problems of uneven withering of fresh leaves in the process of black tea processing, the withering process is restricted by the natural environment, the withering time is too long, and the entire process is expensive.
The location of the primary tea factory should be comprehensively considered in terms of transportation, water sources, environment, employment, raw materials, and topography. Before building a factory, the surrounding environment and geology should be in
The types of tea fixation machines include drum fixation machines, steam heating fixation machines, hot air fixation machines, steaming fixation machines, etc. Can be purchased according to the following factors. (1) Purchasing according to the interna
Shaking and withering are both parts of the fermentation. During the withering process of oolong tea, because the leaves are calmly placed, a lot of water will only evaporate from the leaves, and the water in the leaf stalks is not lost, which will lead t
Oolong tea is a unique existence among all teas. It belongs to a kind of semi-fermented tea. This kind of tea is processed through multiple processes such as drying, drying and shaking, as well as finishing and rolling, and the finished product is process
Black tea leaves contain a variety of water-soluble chemical substances, including tea polyphenols, caffeine, sugars, amino acids, proteins, fruit acids, aromatic substances, etc.
The purpose of tea rolling is to make the initial shape, and to break the leaf cells to increase the flavor concentration of the finished tea. In green tea processing, except for a few famous green teas, rolling is generally an indispensable process.
The purpose of black tea fermentation is to promote profound changes in the contents and prepare a substrate for the formation of the unique color, aroma and taste qualities of black tea.
According to China Customs statistics, in September 2020, China’s tea export volume was 29,100 tons
Green tea fixation processing is the key to green tea processing. The purpose of fixation is to use high temperature to quickly destroy the activity of enzymes, prevent the oxidation of polyphenols, and maintain the green color
The purpose of tea rolling step is to make the shape initially, and to break the leaf cells to improve the taste concentration of finished tea. In the processing of green tea, in addition to a few famous green tea, rolling is generally an indispensable pr
After the fresh leaves are spread, the quality of the leaves becomes soft and emits a delicate fragrance. Generally, the moisture content reaches about 70% (the weight loss rate is about 15% to 20%), which is moderate, and can enter the next process.
Black tea withering refers to the process in which the fresh leaves entering the plant will lose water for a period of time, so that certain hard and brittle stems and leaves are wilted and withered.
Green tea fixation processing is the key to green tea processing. The purpose of fixation is to use high temperature to quickly destroy the activity of enzymes, prevent the oxidation of polyphenols, and maintain the green color; the second is to promote the volatilization of low-boiling aromatic substances, emit grassy aroma, and develop aroma; the third is to evaporate part of the water to make the leaves Soft texture, enhanced toughness, easy to knead and shape.
Technical points in the green tea fixing processing:
(1) "High temperature fixing, first use high temperature and then use low temperature". In the early stage of fixing, in order to inactivate enzyme activity quickly and in time, leaf temperature is required to rise rapidly to above 85°C within 1 to 2 minutes, and the maximum time should not exceed 3 to 4 minutes, otherwise red stems and red leaves may appear. After the enzyme activity is completely destroyed, the leaf temperature will decrease, especially when the water content of the fixing leaf is reduced to about 60%, the leaf temperature is too high, which will cause burnt edges.
(2) "Young leaves use high temperature, old leaves use low temperature." Generally speaking, young leaves have high moisture content and high enzyme activity. The temperature is higher during green tea roasting process and the time is relatively longer. Old leaves have low water content and low enzyme activity. The temperature of tea roasting step can be relatively low and the time is relatively long.
(3) Correctly grasp the degree of tea fixing process. For bulk green tea processing, it is generally required that the weight loss rate of fixed leaves is 30%-40%, and the moisture content is 60-62%, which is fixing moderate. For the processing of famous and high-quality tea, fixed tea leaf moisture content is 55%～58% as appropriate. From the sensory point of view, moderate roasted leaves are dark green in color. The leaves are soft and slightly sticky when pinched. The stems can be bent and uninterrupted, and the clasped leaves form clumps. They are slightly elastic, and the greenness disappears.
