Study on the technology of producing wheat beer by secondary fermentationSecondary fermented wheat beer is a beer produced by using the upper fermentation yeast No.354 and the lower fermentation yeast No.308 as production strains, using wheat malt and special malt as raw materials

Both the non-enzymatic decomposition of α-acetolactate and the enzymatic reduction of diacetyl are temperature-dependent. The higher the temperature, the faster the reaction. 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.
