• Sommario/riassunto: Discover the science of beer and beer making Ever wondered just how grain and water are transformed into an effervescent, alcoholic beverage? From prehistory to our own time, beer has evoked awe and fascination; it seems to have a life of its own. Whether you're a home brewer, a professional brewer, or just someone who enjoys a beer, The Chemistry of Beer will take you on a fascinating journey, explaining the underlying science and chemistry at every stage of the beer making process. All the science is explained in clear, non-technical language, so you don't need to be a
