Abstract

The invention provides a withering method of Gongfu black tea. The method comprises the following steps: 1) picking tea tree fresh leaves, putting on a withering rack, and withering for 1.0-1.5 hours, wherein the withering thickness is 0.5-2.5cm, and the leaves are stirred 3-4 times in the withering process; 2) withering the tea leaves in a withering machine with cold air for 50-70 minutes, wherein the tea leaf spreading thickness is 30-40cm; 3) withering with hot air for 30-40 minutes, wherein the hot air temperature is 35-40 DEG C; 4) withering with cold air for 30-50 minutes; 5) withering with hot air for 70-90 minutes, wherein the hot air temperature is 35-40 DEG C; 6) shutting down for 50 minutes; and 7) withering with hot air for 110-130 minutes, wherein the hot air temperature is 35-40 DEG C, and the tea leaves are stirred every 15 minutes in the whole withering process. The method can accelerate the water loss of the fresh leaves and accelerate the conversion of substances in the fresh leaves, and the tea leaves can be withered uniformly and sufficiently. Meanwhile, the method greatly shortens the withering time.

Description

technical field [0001] The invention belongs to the technical field of tea, and in particular relates to a withering method of Gongfu black tea. 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...
