The easiest way is to ensure that the temperature of the grain you want to ferment reaches 30 degrees, that is, directly warm and keep the brewing equipment warm. If you want to make the entire room temperature reach 30 degrees, you can only insulate the plant, and then connect the boiler to the temperature sheet to heat the plant as a whole.
In winter, as long as the temperature is well controlled, raw food can be fermented! Raw meal brewing has a very high temperature requirements for temperature, raw meal fermentation generally temperature above 15 degrees can be fermented, if the temperature is lower than 15 degrees, you must not ferment, this will cause the bottom of the wine rate, less high wine, more low wine, long fermentation time, and may not be out of wine at all! Generally, the temperature in the fermentation room can be used coal stoves, air conditioners, other heaters, etc. You can also choose a thermostat for constant temperature, which is better, but stir frequently so that the temperature is even.
