Abstract

The application of the invention is a divisional application of 201910006366.2. The invention belongs to the field of tea processing, and discloses post-fermented dark tea and a processing method thereof. The processing method of the post-fermented dark tea comprises the following steps: picking fresh tea leaves; performing fixation; performing rolling; performing baking; performing sorting; performing steaming in a cage; performing rolling again; performing drying again; and performing post-fermentation to obtain the post-fermented dark tea. According to the dark tea processing method, the processing technology is simplified, the processing time is shortened, and meanwhile, the advantages of storage resistance, mellow taste and long storage time of dark tea are kept.

Description

[0001] This application is a divisional application of the Chinese application with the application number 201910006366.2, the application date is January 4, 2019, and the invention title is "a blended tea and its processing method". technical field [0002] The invention belongs to the field of tea processing, and in particular relates to post-fermented dark tea and a processing method thereof. Background technique [0003] Dark tea is one of the main teas in China. It is a product made by picking new and old leaves of tea trees and making them through typical processes such as killing greens, rolling, fermenting (fermenting), and drying. It belongs to fully fermented teas. Compared with the green tea processing technology, the black tea processing technology includes the fermentation process. During the heap fermentation and post-fermentation period, the natural substances in the tea are transformed, forming a variety of color and aroma substances, so that the dark tea has ...
