For those of you who are just starting to get “funky”…use this book to help guide you through this fun and often unpredictable journey….This book will also be very useful for those who are already producing sour beers; I'm certain this will be a great reference book to add to your library. I found good nuggets, both artistic and technical, and I am definitely inspired to brew some new sour beers at our brewery.
