Abstract

The invention provides a black tea withering method. The black tea withering method comprises the following steps: 1), picking fresh tea leaves from tea trees, placing the picked tea leaves on a withering shelf, wherein the withering thickness is 0.5-3.5 centimeters and the withering time is 1.5-2.5 hours, and turning the tea leaves for 4-5 times during withering; 2) placing the tea leaves in a withering machine, wherein the spreading thickness of the tea leaves is 40-60 centimeters, and withering the tea leaves by using cold air for 30-45 minutes; 3), carrying out withering by using hot air for 60-80 minutes, wherein the temperature of the hot air is 35-40 DEG C; 4), carrying out withering by using cold air for 50-70 minutes; 5), carrying out withering by using hot air for 30-50 minutes, wherein the temperature of the hot air is 35-40 DEG C; 6) stopping the withering machine for 1 hour; and 7), carrying out withering by using hot air for 130-150 minutes, wherein the temperature of the hot air is 35-40 DEG C. The tea leaves are turned once every 15 minutes during the whole withering processes. The black tea withering method has the advantages of accelerating water loss of the fresh leaves, speeding up internal substance transformation in the fresh tea leaves and so on. By adopting the black tea withering method disclosed by the invention, the tea leaves are uniformly and fully withered; moreover, the withering time is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of tea, and in particular relates to a black tea withering method. Background technique [0002] Withering is the first process of the initial processing of Gongfu black tea, and it is also the basic process for forming the quality of Gongfu black tea. Withering has both the physical dehydration effect and the chemical change process of the contained substances. Through withering, the fresh tea leaves mainly undergo the following two changes: one is to evaporate part of the water, reduce the tension of the fresh tea leaf cells, make the leaves and stems from brittle to soft, increase the toughness of the buds and leaves, and facilitate rolling into strips; The loss of water causes a series of chemical changes in the substances contained in the tea tip, laying the foundation for the material changes in the specific quality of black tea color, aroma and taste. The mastery of the degree of withering has a gre...
