​The main process of beer production is fermentation, which converts the sugar contained in the wort into ethanol and carbon dioxide. In order to achieve the preconditions for fermentation, the water-insoluble components in the malt must first be converted into water-soluble components, especially fermentable sugars.

Dissolved Oxygen Control Measures in Saccharification Production Process1. Closed manholes should be used for paste (sugar) pots, filter tanks, and boiling pots; during the production process, the entrance doors should be closed as much as possible and less opened, so as to minimize the inhalation o

​Polyphenols in beer mainly come from barley and hops. About 80% of them come from barley and 20% from hops. The phenols in barley are about 0.1% ～ 0.3% of its dry weight, mainly distributed in wheat husk, aleurone layer and endosperm. With the dissolution of malt in the process of malting, it is free and brought into wort and beer through the saccharification process. Phenolic substances in hops account for 4%~10% of the dry matter, mainly distributed in the bracts and rachis of hops.

After opening the bottle cap to decompress the beer, sometimes abnormal foaming and drinking will occur, and even a bottle of wine will spew out more than half of the bottle. This is a disease of beer, called beer gushing.Factors that cause beer gushing:1. Main factors(1) Wet barleyA lot of molds gr
