Everything you ever wanted to know about bourbon barrel-aged stout beer

Jim Beam and Goose Island are responsible for this delicious beer

You might not realize it because it seems like a fairly new beer phenomenon, but bourbon barrel-aged stouts have been around for more than 20 years. It all started on a random evening in the early ’90s in South Bend, Indiana. It was a beer, bourbon, and cigar dinner featuring some big wigs in those three industries. In attendance was Goose Island Brewing’s Greg Hall. If you believe in fate, this is where the story of bourbon barrel-aged stouts began.

Hall could have been seated near anyone or he could have had other obligations and might not have attended the dinner at all. But the proverbial beer-soaked stars were aligned that night because the former Goose Island brewmaster met Booker Noe (grandson of Jim Beam and Beam’s master distiller at the time) at that event. Noe told him and another brewer named Seth Gross about the various things he randomly added to bourbon barrels, including water and ice, to create a bourbon version of iced tea. This is where the idea of aging stout beer in ex-bourbon barrels was formed.

Noe got some barrels for Hall and the first batch of the now world-famous Goose Island Bourbon County Stout was made in 1992. In the decades since, it’s become the face of an ever-growing beer style. While Bourbon County is still regarded as one of the best, it’s far from the only bourbon-barrel stout available today.

What is a bourbon barrel-aged stout?

In the simplest terms, a bourbon barrel-aged stout is exactly what it seems to be. First, a brewery makes a stout or imperial stout that is ready to be imbibed. But instead of bottling or canning it right away, it’s added to barrels that previously held bourbon. It’s matured for months to gain extra aromas and flavors from the bourbon-drenched wood.

How long is it aged?

The aging process is different from brewery to brewery. It does seem like 12 months is the sweet spot for most brewers. Founders’ well-known Kentucky Breakfast Stout spends a whole year aging in former bourbon barrels. The same goes for the iconic Goose Island Bourbon County Stout.

What flavors does bourbon barrel aging impart?

A well-made stout already carries aromas and flavors like coffee, chocolate, roasted malts, and dried fruits. Aging in ex-bourbon barrels adds warming whiskey, toasted vanilla beans, charred oak, and raisins. Maturing in former bourbon barrels takes a good beer and makes it great.

How long can you keep a barrel-aged stout?

Just like with a bottle of whiskey, you can keep barrel-aged stouts for years. This is as long as you keep them somewhere that the temperature doesn’t fluctuate too much and stays at a consistent level. A basement is well suited for keeping barrel-aged beers, as it likely stays the same temperature all year long.

Do barrel-aged stouts get better with age?

To a degree, barrel-aged stouts get better with age. In fact, when you go out and buy a bottle, it would behoove you to store it in a basement or root cellar for six months to a year. The longer it ages, the more the flavors can meld, soften, and add new dimensions to the beer. Some drinkers keep their barrel-aged beers unopened for years (and even decades). Just don’t hold on to it too long because oxidation can occur and ruin the flavor profile.

Should barrel-aged stouts be refrigerated?

Unlike your favorite lager that you immediately put into the refrigerator to make sure it’s cold, putting a barrel-aged stout right into your fridge isn’t the best idea if you want to actually get the most out of it. If it’s too cold, the aging process and overall flavors might be muted. If it’s too warm, the aging process might speed up, as well as potential oxidation.

Now that you have learned a little bit about bourbon barrel-aged stouts, it’s time to find some to drink. And since we’d rather not make you spend an afternoon blankly staring at online retailers or the massive beer cooler at your local grocer or beer store, we did the work for you.

We're making more white oak barrels than we can sustain
Bourbon barrels

If you’ve ever looked into the process of making whiskey (specifically bourbon), you know that there are a lot of rules and regulations, but (on top of the ingredients themselves) there are few steps more important than the aging process. Equally invaluable is the actual wood the bourbon is matured in. While some distillers experiment with other woods for extra aging and finishing, white oak is the only acceptable barrel for straight bourbon. This is why it’s so discouraging to learn about a new report that says that whiskey makers are starting to run out of viable trees.

Something must be done quickly, or soon you might either not be able to get your hands on your favorite bourbon — or you’ll have to pay an uncomfortable amount to get it. You still don’t understand? Let’s start with a little refresher about what makes a bourbon.
How bourbon is made
While whiskey (spelled ‘whisky’ everywhere but the United States and Ireland) is made all over the world from Scotland to Taiwan and everywhere in between, you can only make bourbon in the U.S. America’s “native spirit” is also governed by a few unflinching rules and regulations.
