Embodiment 1
[0070] A kind of processing method of black tea, it comprises following concrete steps successively:
[0071] 1) Raw material selection and picking
[0072] Raw materials: The variety is selected from Bayu Tezao. The raw materials are collected from pollution-free ecological tea gardens at an altitude of 550-650m, and the optimum temperature for picking in sunny days is 25°C. The picking standard is one bud and one leaf, the length of the buds and leaves is 2.5-2.8cm, the buds and leaves are complete and even, and there are no purple leaves, fish leaves, diseased leaves, etc.
[0073] 2) wither
[0074] Withering: When the outdoor temperature is lower than 30°C, the fresh leaves are evenly spread on the withering curtain or dustpan, and the amount of spread leaves is 0.6kg / m 2 , sunbaked for 15 minutes, and then moved indoors to continue withering. The indoor temperature was 25°C, the relative humidity was 75%, and the thickness of the spread was 10 cm, so that the leaf lay...
