After the tanks are sealed, the rise of the tank pressure is related to the speed and quantity of carbon dioxide production, and also to the pressure-holding conditions of the beer storage tank. Therefore, there may be the following reasons for the pressure rise of the tank after sealing:

Flavor from yeast and beer fermentationYeast cells are not the final product in beer production, but are indeed important to the quality of the final product beer. The most important thing in the selection of yeast production strains is the speed of fermenting wort and the degree of fermentation of wort.

After the first wort (original wort) is filtered, a certain amount of extract remains in the wort layer. In order to ensure the utilization rate of raw materials, this part of the extract needs to be recovered, and these soluble components can be washed out with hot water. The process is called scouring.

Controlling the pressure of the wine storage tank is one of the important contents to control the CO₂ content of beer. In the production of beer by traditional fermentation methods, the CO₂ contained in beer is mainly produced by the fermentation process (including main fermentation and post-ferment
