As homebrewers, we love the complexity that barrel aging brings to a beer, but not all of us have the space, time, or resources to maintain a proper barrel-aging program. That’s where this experiment comes in.

In our latest test, we took a classic Oatmeal Stout and infused it with a homemade bourbon and oak tincture, creating an instant barrel-aged effect.

There were no months of waiting or special storage conditions.

Instead, Mike figured out a quick way to add those deep, oaky bourbon notes to a beer. Along with the speed, he had full control over the final flavor. Learn more about his technique in this video!

The Quest for Barrel-Aged Flavor Without the Barrel

Making the “Jar of Darkness”

To create the bourbon barrel effect without the barrel, Mike soaked French oak cubes in not-so-great bourbon for nine months. This soak allowed the alcohol to extract intense wood characteristics.

After the nine month period, Mike had a super-concentrated infusion, darkened and enriched with vanilla, caramel, and toasted wood flavors. He joking called it the Jar of Darkness.

When it came time to test it, we started small with just a couple of milliliters of the tincture added to a few ounces of the Oatmeal Stout. From the first whiff, we could tell the transformation was immediate.

The beer took on layers of bourbon warmth, rich vanilla, and deep oak character. The stout’s original smooth roast and chocolate flavors were still present, but they now played a supporting role to the bold barrel-aged notes.

A Simple and Effective Barrel-Aging Hack

The best part about this technique is how customizable it is. By adjusting the amount of tincture added, you can dial in the perfect balance of bourbon and oak for your taste.

If you want just a hint of vanilla, add just a touch. If you’re looking for an over-the-top bourbon bomb, well, amp it up!

In addition, this method isn’t limited to stouts. You could experiment with Amber Ales, Porters, or even commercial beers to see how the flavors evolve. After tasting our results, we’re convinced that this is a homebrewing hack is worth trying out.

So, if you’re craving that barrel-aged experience without the hassle, it’s time to make your own “Jar of Darkness” and take your brews to the next level.

Maybe you can make your own instant barrel-aged Oatmeal Stout.
