Cowdery is a well-regarded bourbon blogger and writer; as I’m a fan of the spirit, I sought out his book, which I think he self-published. It’s a bunch of solid articles, but it lacks the editing polish and overall coherence we associate with big-publisher books. That’s a nit, though; Cowdery’s book is a compulsively readable survey of the history of bourbon — which is a pretty fascinating tale. Aging, for example, comes late to the party; 18th century American corn whiskey was, typically, unaged and therefore clear. (Why bourbon is typically aged much less than Scottish whiskys is also an interesting tale, by the way.)
Cowdery also gives us a great survey of who, actually, is making bourbon today. It’s fewer people than you’d think — there’s no end of contract distilling and label opaqueness. The bourbon boom that happened after this book went to press have just made those problems worse. (Seriously, look at a bottle and see if you can really and truly tell where the whiskey was made. Odds are, you can’t, but for a very small number of brands.)
Anyway, it’s a good and quick read, but it might be worth waiting to see if Cowdery plans to update it in light of the modern developments in the whiskey market. Even if he doesn’t, though, it’s worth your time.
