The Brewtal Truth Guide to Extreme Beers is the first guide of its type, defining what makes certain craft beers “extremely extreme,” featuring descriptions and ratings of more than a 100 of the most insane beers in the world—broken down into a handful of specific categories. These are outrageous brews with unusual ingredients, ridiculously high alcohol by volume (ABV), bizarre names and sometimes unsettling flavors.

Appealing to casual and serious beer drinkers alike, the book is the perfect gift for the adventurous guy (or girl) who’s always looking for new experiences; the book is a reference guide and a challenge all at once. In addition to focusing on some of the most interesting and hardcore beers in the world, it also features profiles on craft-beer loving metal musicians and extreme craft beer brewers, making it a highly entertaining read. The book sets the scene for what an extreme beer is, drawing parallels and metaphors from the music scene. The author includes an explanation of extreme styles and what defines them. Each beer profiled receives an “extreme” rating, tasting notes  information about the beer and what makes it extreme, and a musical pairing selected by the author. There is also a resources section where readers can find recommendations on how and where to buy these brews. Working in partnership with Decibel Magazine, and created out of his Brewtal Truth column with Decibel, Adem Tepedelen opens up the fun and fascinating world of extreme beer.
