Do you need to have an advanced science degree to understand brewing chemistry? Certainly not! Any brewer, explains author Lee W. Janson, can understand the basic details of the life of a yeast or the careless steps that produce those annoying off-flavors - and learn how to avoid them. Brew Chem 101 features nontechnical language and a highly readable style, explanations of the chemical reactions at each stage of the brewing process and how to avoid potential problems, and a primer on beer tasting and judging.
