Can wine be fermented in winter 10?

Rice wine cannot be fermented at 10, and the temperature of brewing rice wine should be controlled at about 30. After the distiller's yeast and rice are mixed evenly, they are put into a fermentor. Under the action of microorganisms, the temperature in the fermentor will rise slowly, and the microorganisms in koji will decompose the starch in rice into sugar.

If the temperature is too low, it will easily lead to the slow reproduction of microorganisms in koji, while other miscellaneous bacteria will have the opportunity to grow, so the brewed rice wine tastes sour. In the low temperature environment in winter, heat preservation measures must be taken when yellow rice wine is fermented. Otherwise, rice wine may not be fermented completely for more than a week.

Precautions:

Keep warm: It is natural to wear more clothes in cold weather. When the room temperature is below 20 degrees in winter, it is essential to take necessary heat preservation measures. The temperature of the fermentation chamber may not be kept at 25-30 degrees, but the temperature should not be lower than 20 degrees.

Try to control the temperature difference between day and night between fermentation rooms: In many provinces in northern China, it is also common to wear cotton-padded clothes in the morning and evening and short sleeves at noon. If the fermented grains can not provide relatively stable conditions in the fermentation process, and the temperature difference between day and night is too large, it will not only lead to a long fermentation period, but also lead to a low wine yield due to incomplete fermentation.
