Beers aged in something other than bourbon barrels? Thrillist drops this list of aged beers from across the globe. From Colorado's Avery Brewing (who ages their Black Tot in Gosling's rum barrels) to Harviestoun's Ola Dubh, an ale aged Highland Park whiskey casks, "there's no question [barrel aging] has pushed it to new, exciting, and delicious heights in recent years."
