It should be considered that different concentrations of fermented wort require different amounts of yeast added. If the concentration of fermentation is high, the amount of yeast added should be more. A high concentration of wort means that there are a large number of components that need to be metabolized and transformed by yeast, and the proportional relationship between the substances and the medium needs to be balanced.

The preparation of wort, that is, the formulation of the saccharification process, is only to meet the action conditions of maltase and external enzymes. Therefore, the saccharification process conditions, including temperature, pH, material-water ratio, raw material ratio and even stirring, should

The RA value of water will increase or decrease the pH value of mash and wort, which will have a series of effects on the production process of beer.effect on enzymesIn the process of saccharification, pH value has a significant effect on various enzymes, especially α-amylase.

Influence of feeding temperature on beer qualityNew research shows that if a high temperature (such as 62°C) feeding process is used, not only the saccharification time is short, which is beneficial to energy saving, but also it is very beneficial to the foam and taste stability of beer
