Being a homebrewer for 4 years, I have found that Brewers Publications' Classic Beer Styles Series is an excellent resource for discovering and making numerous quality brews. In Altbier, Horst Dornbusch tackles a style that few people may have ever had. His approach is practical and to the point. The history section is thorough without being long-winded, as is sometimes the case with other books in the series. Mr. Dornbusch has done an excellent job applying his own brewing knowledge in explaining the ins and outs of altbier brewing. I have followed some of the recipes in the book, and I am extremely pleased with the results so far. The only downside to this book is that the section on style profile could have been more thorough and descriptive. However, this book is well worth the investment.
