What is more, the rising of the fermentation temperature will make the fermentation process significantly faster. Low temperature fermentation can improve the color and flavor of beer. While high temperature fermentation can accelerate the fermentation speed, improve the production efficiency and economic benefits of the enterprise. If the fermentation temperature is too low, it will make a slow fermentation process, affecting the production schedule. On the other hand, if the fermentation temperature is too high, it will cause the biochemical parameters exceed the production standard, affecting the quality of beer. Therefore, the fermentation temperature needs to be strictly controlled throughout the entire period the beer fermentation.
