As a home brewer I was looking for a book on commercial / micro brew pub info. A seven barrel brewery is a specific engineered brew system that brews 7 barrel batches of beer at one time. I was disappointed that this book had nothing to do with describing the workings of a 7 barrel system / brewery as I was putting together a business plan to open a commercial brew pub. So it was an overpriced beginner's book for recipes and techniques to home brew. Much better books on the subject I already own.
