Embodiment 1

[0078] Example 1. A processing method of controllable Duyun black tea, prepared according to the following steps:

[0079] Include the following steps:

[0080] (a) Picking fresh leaves: Picking fresh leaves with one bud and three or four leaves of Duyun native species;

[0081] (b) Spreading: the fresh leaves are spread indoors for 3 hours at a room temperature of 25°C, and the dehydration reaches 70%;

[0082] (c) Greening: Roller greening machine, leaf amount 2.5kg, 200°C greening; until green odor disappears, tea fragrance is revealed, leaf color changes from bright green to dark green, sticky to form a ball when pinched;

[0083] (d) Kneading: Knead while hot for 25 minutes, light pressure for 5 minutes, medium pressure for 10 minutes, light pressure for 5 minutes;

[0084] (e) Drying: unblock, dry in the sun for 5 hours at room temperature at 25°C to form a sun-dried taste, knead lightly for 5 minutes, and dry at 40°C to obtain sun-dried green tea;

Abstract

The invention discloses a controllable processing method for Duyun dark tea. The method includes fresh leaf picking, spreading-out, green killing, rolling, drying, sterilizing, bacterium preparing, inoculating, piling and drying. The method is stable in preparation, can effectively enhance the quality of tea leaves of Duyun dark tea, and can improve the fragrance and taste of the Duyun dark tea; the prepared Duyun dark tea is rich in nutrient content, stable in tea quality and good in color without containing T2, HT2 and four kinds of aflatoxin; and the tea leaves are dark brown and uniform inappearance, aged fragrant and pure in fragrance, reddish brown in soup, mellow in taste and deep brown in bottoms of the leaves.
