Query: Homebrew World-Altering

The strange title fits. It is written with wit, humor, passion and loads of knowledge. I've got a couple dozen brewing books, but I keep coming back to this one.Like others, it covers the basics of techniques. Each chapter examines a different genera of beer, origins of similar beers, how they were brewed, how they evolved, how to brew similar beers (both all-grain and extract) and how you might personalize them. While Ray Daniels does a great job of nailing a style, Randy Mosher pushes well beyond the boundaries of defined styles and inspires you to be creative.Do you want to know how to use an unusual adjunct? How about the qualities of various spices? Fruits? Stranger ingredients? Randy provides example of historical brews using stuff I never would have dreamed of putting into my beer, and leaves you eager to try something new.
