I picked up this book not really knowing what to expect. From the description, it wasn't totally clear to me if this is a book for homebrewers, people trying to work in the industry, or general beer lovers. In fact, my local library stocks this book under "careers." This is definitely a great book for homebrewers and beer enthusiasts alike, but for those looking to learn more about industry careers, I'd look elsewhere.
The book alternates between chapters on brewing ingredients, equipment, and techniques with chapters that dive deeper into those subjects from some of the most respected brewers in the industry. It's like reading the "Tips from the Pros" section of BYO, told from the experts you'd most want to hear from on a subject: Bill Covaleski (Victory) on lagering, Vinnie Cilurzo (Russian River) on hops, Sam Calagione (DFH) on brewing with fruit, and, best of all, Jean Van Roy (Cantillon) on lambics/sours. Plus several others. Although the brewing instruction chapters are good (I think a brewer of any level could learn something from them), these "expert" chapters are where this book really shines. Told in an interview style, it feels like you are having a conversation with these experts (in some cases legends) of brewing.
Finally, the photography in the book is top notch. Some of the best I've seen in a brewing book. This book would do well on a coffee table as in your brewing library.
