The use of wooden vessels for storage, transportation, fermentation, or aging of beer is deeply rooted in history. Today's talented brewers are innovating, experimenting, and enthusiastically embracing the seemingly mystical complexity of flavors and aromas derived from wood. From the souring effects of microbes that take up residence in the wood to the wood character drawn from barrels or foeders, this book covers not only the history, physiology, microbiology, and flavor contributions of wood, but also the maintenance of wooden vessels. Explore the many influences of wood as a vehicle for contributing tremendous complexity to beers fermented and aged within it. Wood & Beer: A Brewer's Guide is as much about wood as it is about beer, and the mysteries that arise when the two come together.
