2022-10-10 The fermented liquor after the main fermentation of wort is called green beer, also known as new beer. At this time, the carbon dioxide content of the beer is insufficient, and the volatile flavor substances such as diacetyl, acetaldehyde, and hydrogen sulfide have not been reduced to a reasonable

Therefore, if the main fermentation temperature is increased, or the fermentation temperature is maintained at a higher temperature before the end of the main fermentation, the diacetyl is reduced quickly, and the post-fermentation time of the beer is greatly shortened.
