These two books are musts for any beer library. You had better have a beer library or at least one book by Michael Jackson. Beer School is a great business accented account of how the Brooklyn Brewery was born and nurtured to where it is today. Very interesting on the intricacies of selling beer and creating a entreprenurial mind set.
To cover the beer and food pairing phenomenon, you have to read The Brewmaster’s Table. It is an excellent guide to food and beer. If you don’t learn something new, then you are the one true beer geek god.
