It has been a hot minute since the Brewers Association tackled the ever expanding IPA style in book form but I think they found a brewer who has some good info to impart, Dick Cantwell who is back brewing in the Bay Area has a new book out that tackles the odd side of hoppy beers.
Brewing Eclectic IPA covers “a wide range of ingredients, from cocoa nibs, coffee, fruits, and vegetables, to spices, herbs, and even wood, to push the boundaries of the style.”
Here is the blurb: “Among the most well-respected and experienced craft brewers in the world, Cantwell provides scores of tips and methods for first-time brewers and beer veterans alike to concoct a delectable brew and shares the story of how and why the proliferation of American IPA came to be.”
