Patrick E. McGovern takes us on a fascinating journey through time to the dawn of brewing when our ancestors might well have made a Palaeo-Brew of wild fruits, honey, cereals, and botanicals. Early beverage-makers must have marveled at the magical process of fermentation. Their amazement grew as they drank the mind-altering drinks, which were to become the medicines, religious symbols, and social lubricants of later cultures.

McGovern recounts how the re-created Ancient Ales and Spirits of Dogfish Head came about as he circles the globe-to China, Turkey, Egypt, Italy, Scandinavia, Honduras, Peru, and Mexico. He interweaves archaeology and science and tells the stories and struggles in making the most authentic versions possible of these liquid time capsules. Accompanying homebrew interpretations-brimming with unusual spicy, fruity, and malty aromas and tastes-help bring the past alive, as our senses and imaginations travel "Back to the Future."
