Abstract

The invention discloses a preparation process for black tea with a bamboo fragrance. The preparation process comprises the following steps: picking fresh leaves; withering; rolling through a three-step method; fermenting for the first time; drying for the first time; fermenting for the second time; drying for the second time; mixing tea leaves with bamboo leaves for the first time: alternately and repeatedly stacking the tea leaves and the bamboo leaves layer by layer according to the weight ratio of the bamboo leaves to the tea leaves of (1-2):8 in a closed room and mixing for 6-8 h; mixing the tea leaves with bamboo leaves for the second time: transferring the tea leaves and bamboo leaves into a steam tank, and heating the tea leaves and bamboo leaves by steam for 3-5 min at 100-105 DEG C; screening; drying for the third time. After the black tea prepared through the preparation process disclosed by the invention is brewed, the tea soup is red bright, has the fresh and long-lasting bamboo fragrance, and is sweet in aftertaste and refreshing.

Description

technical field [0001] The invention relates to the field of tea production, in particular to a production process of bamboo-fragrant black tea. Background technique [0002] Black tea is a fully fermented tea. During the processing of black tea, a chemical reaction centered on the oxidation of tea polyphenols occurred. The chemical components in fresh leaves changed greatly, and tea polyphenols were reduced by more than 90%, producing theaflavins, New ingredients such as thearubigin. The aroma substances are significantly increased compared with fresh leaves, so black tea has the characteristics of black tea, red soup, red leaves, sweet and mellow.
