After a couple of placeholder covers online and in print ads, here is the real deal. The glassware and fill-level were both topics of great debate (I only had a minor say). Luckily I'm really pleased with the result! It looks a bit more slick and modern than the Belgian trilogy (Brew Like a Monk, Farmhouse Ales, and Wild Brews), which is in keeping with the topic. If anyone is wondering, that's New Belgium La Folie in the glass.
I'm sure you're all tired of reading about the book after three years, so you'll be glad to hear that American Sour Beers will be released in less than a month. Your first chance to have a copy in your hands will be at the 2014 National Homebrewers Conference in Grand Rapids, MI. Coincidentally... I'll also be presenting (twice) about The Influence of Mashing on Sour Beer Production. There will be an online pre-sale for AHA members soon, and everyone who pre-orders on Amazon will be getting it around the same time. There will also be a Kindle version released in a few months if you prefer reading electrons instead of ink.
