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
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. The essence of black tea fermentation is a chemical change process with the profound oxidation of polyphenol compounds as the core. How to control the fermentation time and temperature of black tea?
Black tea is normally fermented for 4 to 6 hours. However, the specific fermentation time depends on the age and tenderness of the tea, the cold and hot weather, the dryness, wetness, and the degree of twisting. Generally, young leaves, well-kneaded raw materials, and high-fermentation temperature leaves ferment quickly and the time is relatively short. Otherwise, the time will be longer. I have encountered that it has not been fermented for 12 hours. As long as it is not sour or stuffy during fermentation. The tea maker must keep track of the fermentation progress.
Fermentation time is only a reference indicator. Whether fermentation should be terminated, or should it be based on the degree of fermentation. Moderate fermentation is generally based on the fact that the leaf color changes to reddish-yellow, the blue aura disappears, and the floral and fruity aroma appears as the standard. If it is mass production, finally use the evaluation method to look at the color of the soup, taste the taste, look at the bottom of the leaf, and check the degree of fermentation. The book says how much temperature and humidity are, and how many hours are normal. The top tea maker only says "watch tea and make tea". The way inside is very mysterious!

Black Tea Fermentation Temperature
Temperature has a great influence on fermentation quality, including air temperature and leaf temperature. The level of temperature directly affects the leaf temperature. During the fermentation process, the polyphenol compounds are oxidized and exothermic, which increases the leaf temperature. The leaf temperature has a changing law from low to high and then low. Fermentation leaf temperature should be kept at 30℃, and the temperature should be 24℃～25℃. The temperature and leaf temperature should not be too high or too low. If the leaf temperature is too high and exceeds 40°C, the fermentation changes will be too intense, resulting in low aroma and low taste and dark color, which will seriously damage the quality. Therefore, cooling measures should be taken in the high temperature season, and the spread leaves should be thin to facilitate heat dissipation and cooling. If the temperature is too low, the fermentation time will be prolonged and the endoplasmic transformation cannot be fully developed. Therefore, when the leaf temperature is too low, the leaf layer should be thickened to facilitate heat preservation, and other heating measures should be taken if necessary.
