Brewer's yeast belongs to the genus Saccharomyces, and in an acidic, sugary aqueous solution (wort), through the outer cell membrane (plasma membrane), they absorb dissolved sugars, simple nitrogenous substances (amino acids and very small molecular peptides), vitamins , ions and other substances, a

The purpose of malting: through operation, let the barley absorb a certain amount of water, and germinate under appropriate conditions, activate the enzymes in the barley and produce various hydrolytic enzymes, so that the components in the endosperm, such as the starch and protein in the grain Etc., under the synergistic action of enzymes, it is moderately dissolved; the green malt can be dried and roasted to remove excess water, remove the green taste of green malt, and produce the unique color, aroma and flavor components of beer; Finally, the composition of malt can be stabilized for long-term storage.

wort filtrationAt the end of the saccharification process, the decomposition and extraction of high-molecular substances in the malt have been basically completed, and the wort must be separated from the grains in the shortest possible time, that is, the water-soluble extract and the residual husk,
