CHICAGO — Goose Island Beer Co. is taking its long-running relationship with bourbon barrels to a new level with the introduction of Bourbon County Brand Triple Barrel Stout, a beer aged for three years across three successive freshly emptied bourbon barrels.
The limited release marks the first time Goose Island has used the triple-barrel process for its Bourbon County Stout lineup, extending an aging program that helped establish bourbon barrel-aged beer as a major category within American craft brewing.
Rather than allowing the beer to mature in a single bourbon barrel, Goose Island transfers the stout into a new freshly emptied bourbon barrel during each stage of the three-year aging process.
The idea is to allow each barrel to contribute another layer of bourbon, oak and flavor to the finished beer.
Bottled at a formidable 18.7% alcohol by volume, Bourbon County Brand Triple Barrel Stout is built on a rye stout base and is described as intentionally barrel-forward.
Goose Island says the finished beer delivers flavors of rich milk chocolate and warming vanilla alongside pronounced bourbon and oak characteristics developed during its extended barrel maturation.
The process also highlights the relationship between two distinctly American drinks — bourbon and barrel-aged stout.
Before a barrel ever reaches Goose Island’s Chicago Barrel House, it has already completed a lengthy journey of its own.
American oak is harvested and seasoned before being shaped and charred by a cooperage. The new barrel then travels to a bourbon distillery, where whiskey can spend years extracting flavors from the charred oak.
After the bourbon is dumped, a freshly emptied barrel still contains whiskey absorbed deep within the wood along with the compounds developed during years of maturation.
Brewers have learned to take advantage of those characteristics by filling freshly dumped bourbon barrels with beer, allowing the stout to pull additional whiskey, vanilla, caramel, spice, char and oak flavors from the wood.
With Triple Barrel Stout, Goose Island repeats that interaction three times.
Each transfer places the beer into another freshly emptied bourbon barrel, exposing it to a new source of bourbon-soaked oak rather than leaving it in the same cask for the entire maturation period.
The result is intended to showcase not only Goose Island’s barrel-aging program but also the influence bourbon barrels can continue to exert even after the whiskey they were originally built to age has been removed.
The release is another chapter in a beer program with particularly important ties to the American whiskey industry.
Goose Island’s Bourbon County Brand Stout traces its history to the early 1990s and has become one of the best-known examples of beer matured in used bourbon barrels. Over the years, the brewery has experimented with different barrel types, maturation periods and stout variations.
Triple Barrel Stout takes that experimentation in a different direction by focusing on repeated exposure to freshly emptied bourbon barrels.
That approach also demonstrates why used bourbon barrels have developed into a valuable secondary product for Kentucky distilleries.
Federal standards require bourbon to be aged in new charred oak containers, meaning those barrels cannot simply be refilled with another batch of bourbon. Once dumped, however, they can be used to mature beer, Scotch whisky, rum, tequila and other spirits and beverages.
That secondary market has allowed Kentucky bourbon barrels to influence drinks produced around the world long after their original whiskey has been bottled.
For Triple Barrel Stout, the barrel itself becomes one of the central ingredients.
Goose Island is producing the beer as a highly limited release rather than distributing it nationally.
Bourbon County Brand Triple Barrel Stout will be sold in 16.9-ounce bottles exclusively at Goose Island’s Chicago properties, including its Taproom and Salt Shed Pub.
The limited availability and three-year production process make the release one of the more unusual expressions to emerge from Goose Island’s Bourbon County program.
At 18.7% ABV and after three separate encounters with freshly emptied bourbon barrels, Triple Barrel Stout also pushes the connection between American craft beer and bourbon further than the brewery has previously taken it.
