Barrel-aged beer is produced by brewers around the United States to achieve a variety of flavorful effects. Tannins and lactones of the wood are imparted to the beer as it ages over a period of time. Barrels that previously held bourbon, whisky, or wine are frequently used to add other flavors, with bourbon barrels by far the most commonly used. Goose Island's Bourbon County Stout was one of the first bourbon barrel-aged beers made in 1992.
