Water requirements for brewing beer
Water is the basis of brewing beer. The quality of water directly affects the overall quality of beer. The high RA value of water will increase the pH of wheat mash and wort, which will have a series of effects.
(1) Influence on enzymes The most suitable pH value of enzymes in the saccharification process, such as α-amylase, β-amylase, β-glucanase, protease, peptidase, R ~ enzyme, phosphatase, etc Both are relatively low, and the pH value is too high, which will inhibit the action of enzymes and fail to achieve the decomposition effect of the corresponding substances, which is unfavorable for the saccharification process and thus also affects the fermentation process and beer quality.
(2) Influencing the yield of wort due to the restriction of enzymes, the decomposition of starch and protein is incomplete; poor decomposition of β-glucanase, high wort viscosity, difficult filtration, and dirty washing, so it affects wort Yield.
(3) Influence on wort properties The higher the wort pH value, the more polymer polyphenols leached from the wheat hulls, which will deepen the color of the beer, rough taste, and easy to be cloudy.
