Yeast

Yeast Yeast is available in two forms, dry and liquid. It also divided into a wide variety of strains. The dry varieties are usually general ale yeast providing an easy reliable fermentation, however their characteristics may be variable and their purity questionable. Liquid cultures provide the brewer with pure strains suited to specific styles of beer. The liquid cultures require a little more attention as the yeast require a start up period of one or two days. Liquid cultures are also the best source of true cold fermenting lager strains. Most dry yeast users will notice a decrease in fruity esters and a longer fermentation with liquid yeast.
