This is a very informative book from a very impressive beer connoisseur. The only reason I give it 4 stars is because he neglects Stone Brewing Company which in my opinion is one of the best Brewing Companies in the world. The main aspect of this book that is so great is that he gives reviews and descriptions of beers that a lot of people would be unfamiliar with. Such as beers from the Czech Republic. Also Michael Jackson gives critics on beers throughout the world. It is very impressive because he covers so many countries in this book. Another thing that is typical of Michael Jackson's book is his excellent descriptions of the types of beer and also the ingredients in beer. This is very educational, and if you want to know of some great beers this is a very informative guide.
