Brewing Agent is a term used to describe the three components used in the brewing process: YEAST (5 letters), ENZYME (6 letters), and Malt (4 letters). YEAST is a single-celled organism that is used to convert sugars into alcohol and carbon dioxide. Enzymes are proteins that act as catalysts to speed up chemical reactions. Malt is a grain, usually barley, that is germinated and dried to produce enzymes and starches that can be converted into sugars. Together, these three components are essential for the brewing process.
