Oskar Blues Brewery’s most popular stout is getting yet another variant.

According to a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), Barrel-Aged Mocha Ten Fidy is a 12.9 percent ABV imperial stout aged in bourbon barrels with coffee sourced from Hotbox Roasters and cacao from Boulder, Colo.-based Cholaca that will be packaged in 19.2-ounce cans. As the name suggests, the base beer is the Longmont, Colo.-based brewery’s Ten Fidy, a 10.5 percent ABV imperial stout.

Oskar Blues has released a number of Ten Fidy variants over the years, including Barrel-Aged Ten Fidy, Java Barrel-Aged Ten Fidy and Rum Barrel-Aged Ten Fidy.

In addition, the brewery has recently filed a label for another variant named Barrel-Aged JahVanilla Ten Fidy, 12.9 percent ABV imperial stout aged in bourbon barrels with vanilla and Jamaican coffee beans sourced from Hotbox Roasters.

An email sent to the brewery for additional information was not immediately returned.
