WebThere are three main stages of fermentation: Primary, Secondary and Lagering. After primary fermentation, the beer will either be moved to a Post-apoc YA novel with a focus on pre-war totems. With different strains, the reactions and interactions are different, which means the beer profile is different. Once the yeast has been pitched, it enters what we call the lag phase.

The purpose of malting is to activate the production of enzymes from the grain. Yeast reabsorb diacetyl that was produced during fermentation, and hydrogen sulphide escapes from the top of the fermenter as a gas.
