As a librarian, I get to see a lot of books on this subject and I have found this particular book to be exceptionally well done in nearly every respect. I appreciate the history lesson included within, because in order to brew quality examples of these fine Belgian and French ales I think it important to understand the historical impact of them and how the styles have grown and evolved over the years.Having said all of that though, I find this book's practical advice and information about the actual brewing of these beers to be the most valuable. I love Belgian saison beers, and with a handful of tips I gleaned from this book I was able to brew a deliciously complex example on my first try. The beers I brewed after that only got better.If you are a brewer who likes to experiment with new styles or more advanced techniques, this book is definitely worth having. Highly recomended!
