A good overview that dips into science, history and the making of beer without getting too deep, yet with a bit more detail than some of the other overviews. Contains a good number of charts and diagrams that help illustrate some of the details, as well as a great bibliography.

Less a book about beer and more a chemistry/biology/genealogy text book, this was a interesting if somewhat dry and occasionally heavy-going book that I sometimes had trouble following. On finishing it, I felt like I needed a drink. Still, at least I now know what causes the hangover. 

If you want a history of beer, as opposed to a natural history, I would point you more towards Pete Brown, an author who gets name-checked at least three times in this book.
