This book was exactly what I was looking for: a reference with a lot of recipes and descriptions of the different types of hops, malt, adjuncts, etc. Beer styles are presented in a table giving you an idea of what types of ingredients are used and options that are available. This is a handy quick reference if you want to "wing it" with a little bit of a safety net. Then, about half of the book is specific recipes of varying dificulty, also organized by style.
I gave this book four stars instead of 5 because on the back it says it's the only book you'll ever need. If you're just starting out, I disagree. There are a few chapter's on the basics, however, this book would have been a little confusing if I hadn't first read Papazian's Complete Joy of Homebrewing. The Complete Joy of Homebrewing will get you going. The Brewmaster's Bible will keep you going. If you're looking for a good reference, I highly recommend this book.
