Beer is carbonated because carbon dioxide gas is dissolved in it. The carbon dioxide gas forms when yeast ferments the sugar in the beer. The carbon dioxide gas makes the beer fizzy and gives it its carbonation. Carbonation also helps to preserve the beer and prevent it from going bad.Carbonation ca

The freezing point temperature at which beer or fermentation liquid freezes can be calculated by referring to the following formula:T ice = - (alcohol content × 0.42 + wort concentration × 0.04 + 0.2)

The basic principle of beer fermentation tanks: After the wort is prepared and cooled, yeast is added, transported to the fermentation tank, and fermentation begins. The traditional process is divided into pre-fermentation and post-fermentation, which are carried out in different fermentation tanks.
