The quality inspection of hops and hop products can be divided into two parts: appearance inspection and physical and chemical index analysis.

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.

Causes of turbidity and precipitation in beer1. Biological turbidity:In short, bio-turbidity of beer occurs for two reasons:First, the fermentation process contaminates other microorganisms, causing the death temperature of beer to rise.

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.
