Method for producing natural leaf alcohol by variable-temperature fermentation of tea leaves

The invention provides a method for producing natural leaf alcohol by variable-temperature fermentation of tea leaves, which comprises the following steps: S1, putting fresh tea leaves into a fermentation tank, performing variable-temperature fermentation, and controlling the humidity to be 90-100%; the temperature change range is 20-50 DEG C, and the temperature rise speed is 0.8-1.2 DEG C/h; after the temperature reaches 50 DEG C, the temperature is kept unchanged, and fermentation is continued; the total fermentation time is controlled to be 30-40 hours. According to the method, the leaf alcohol content in the tea leaves can be obviously increased by treating the tea leaves in a variable-temperature fermentation mode, and the leaf alcohol content can be increased from 2% to 28% or above; compared with constant-temperature fermentation, the fermentation is obviously improved; the total yield of post-treated leaf alcohol is greater than 85%; the method is suitable for industrial production. 本发明提供了一种茶叶变温发酵生产天
