Last year, Jackie O’s Pub & Brewery and Side Project Brewing released a barrel-aged stout that combined a popular creation from each of them. This year, there may be two different versions of the stout packaged in 375ml bottles.

The first is Bourbon Barrel-Aged Appervation 2018, a 14 percent ABV imperial stout aged in bourbon barrels for 14 months, while the second variant is Port Barrel-Aged Appervation 2018, an 11.3 percent ABV imperial stout aged in port barrels for 12 months. As the names suggest, the stouts are actually a blend of one of each brewery’s signature stouts: Jackie O’s Dark Apparition Russian imperial stout (10 percent ABV) and Side Project’s Derivation imperial stout (15 percent ABV.)

The first incarnation of Appervation debuted at both Jackie O’s Taproom & Brewery and Jackie O’s Brewpub & Public House last May packaged in 375ml bottles ($15.99) and featured a 12 bottle per person limit.

“A conscious and meaningful brewing effort between friends and lovers of barre-aged beers; formulated as a blend of our signature barrel-aged stouts, we both selected techniques and ingredients that pushed both our skill sets,” reads the labels filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB.) “Inky, warm, dark and extravagant, swelling you into a deep abyss of liquid love.”

When reached by email, a spokesperson for the brewery declined to comment on the release.
