Abstract

The invention discloses a production method of Yunnan large-leaf yellow tea. The production method comprises the following steps: picking fresh leaves, spreading, carrying out fixation, carrying out primary heaping for yellowing for 1 hour, rolling, carrying out secondary heaping for yellowing for 8-10 hours, and drying. Wherein both the primary heaping for yellowing and the secondary heaping for yellowing are that tea leaves are stacked in a metal utensil, then the top of the metal utensil is covered with a wet towel, the metal utensil is placed in a fragrance enhancing machine, and the temperature of the fragrance enhancing machine is controlled to be 45 DEG C. Effective components in the tea leaves can be effectively reserved, the phenol-ammonia ratio is reduced, the liquor color is yellow and bright, the taste is sweet, mellow and fresh, wood fragrance is achieved, the heaping yellowing time can be shortened, and the yellow tea making period is shortened.

Description

technical field [0001] The invention belongs to the field of yellow tea processing, and in particular relates to a preparation method of Yunnan large-leaf yellow tea. Background technique [0002] Yellow tea is one of the six major tea categories in my country. It has a unique beauty in appearance, and ranks among the top three in nutrition, pharmacological components, flavor quality and functional components. It is recommended by tea experts as the most suitable tea for drinking. However, in the entire tea industry, compared with other teas, the upgrading of yellow tea processing technology and products is relatively slow, and the industry scale is small. Dull yellowing is a key process in forming its unique quality. The traditional yellow tea processing technology adopts the conventional yellowing method, which is prone to insufficient or excessive yellowing, resulting in poor tea soup and taste, affecting the quality of yellow tea. SUMMARY OF THE INVENTION [0003] Th...
