Abstract

The invention relates to the technical field of black Fuzhuan tea, in particular to a black Fuzhuan tea surface fermentation process. In the process, when tea leaves are pressed into brick-tea by using a mold, the mold is separated from the brick-tea by a preservative film for preventing moisture from losing. The preservative film can keep humidity on the surface of the brick-tea, thereby an environment facilitating propagation of Eurotium cristatum is formed, and the fermentation of the surface of the brick-tea is facilitated. The brick-tea is sent to a drying room for fermentation and drying. During fermentation, the temperature in the drying room is 26-30 DEG C, and the fermentation is performed for 28-32 days. During drying, the temperature in the drying room is increased 2 DEG C every day, and the drying is performed for 7-9 days. After drying, the water content of the brick-tea is 12-14 percent. Longer fermentation time promotes fermentation of the inside and the surface of the brick-tea on one hand, and the other hand, the activities of the Eurotium cristatum are increased, which facilitates the formation of the flavor of the black Fuzhuan tea, shortens the storing time of the product and accelerates the post-fermentation period of the product.
