More than a year after it was first released, Prairie Artisan Ale’s Barrel-Aged Bomb! is back, but with a twist.

The base beer is still the Tulsa, Okla.-based brewery’s Bomb!, a 13 percent ABV imperial stout brewed with coffee, cocao nibs, vanilla beans and chillies, but this version has been aged in whiskey barrels for “several months” before being bottled. The beer was brewed and bottled at Krebs Brewing Co. in Krebs, Okla. and distributed by Shelton Brothers.

A barrel-aged version of Bomb! has been released before, specifically in late 2014, but that incarnation was a Texas-exclusive that came in at 13 percent ABV and was aged in barrels sourced from Balcones Distillery out of Austin, Texas.

According to a post on Prairie’s website, Barrel-Aged Bomb! is packaged in 12-ounce bottles and is being shipped to retailers in the brewery’s distribution network today, along with 500ml bottles of Ape Snake, a 7 percent ABV “dark farmhouse ale” that has been dry-hopped with both centennial and Falconer’s Flight hops. Ape Snake is also being brewed at Krebs Brewing Co.

An email sent to the brewery asking for information regarding the brand of bourbon barrels the beer was aged in was not immediately returned.
