Book Recommendation: The Oxford Companion to Beer
This isn't one of the beer books that I suggest you read cover to cover.
Instead, this is a beer book to have on your shelf and dip into when you want to go deeper in your beer geekery.
This tome is set out like an encyclopedia with articles set in alphabetical order. Cicerone use it as part of their Road to Cicerone training series, telling you which articles to read to further your knowledge.
Grab a beer and look up it's style in this book for a truly geeky evening!
