Barrel-aged beers are nothing new. The technique of aging stouts and porters and Scotch ales in bourbon barrels was so cool for a while it became passe. Everyone did it, soaking their brews in sweet, charred wood to bring out bourbon notes in some of the denser beer styles.
Everyone did it, but conformity to a trend doesn’t mean the beers aren’t good. Hoppin’ Frog Brewery out of Akron, Ohio, makes some of the better barrel-aged beers on the market. The brewery ages its best-known beer, B.O.R.I.S. The Crusher Imperial Stout, turning it into one of the top-rated beers in the world. By all means seek it out if you have a chance.
