Embodiment 3
[0057] Embodiment 3: the fermentation process of sour rice wine with high acidity
[0058] Dosage of ingredients: based on 100kg of glutinous rice, 17kg of wheat koji, 5kg of rice wine yeast culture solution, 3.5kg of lactic acid bacteria culture solution, and 170kg of water.
[0059] According to the ratio of raw materials, the specific steps of the production process are as follows:
[0060] (1) Rice soaking: After the rice is screened and removed, put it into the tank and soak it in water until the tank is full, wash off the floating foam on the water surface, soak for 24 hours, and drain;
[0061] (2) Steamed rice: Standard requirements for steamed rice: rice is hard on the outside and soft on the inside, loose but not mushy, cooked but not rotten, and uniform;
[0062] (3) Cold rice: Use a blower to blow and cool the steamed rice to 50°C, and control the product temperature in the tank to 24°C;
[0063] (4) Pre-fermentation: Add cooled rice and barley koji, add feed wat...
