For the 12th year in a row, Deschutes Brewery will be releasing a barrel-aged porter to celebrate its birthday, but this year’s version will be in smaller bottles.

That beer is Black Butte XXXII, an imperial porter aged in Columbian rum barrels that incorporates cold brew coffee, vanilla, nutmeg and sweet orange peel.

According to a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), the newest incarnation of Deschutes birthday release will be package in 12-ounce bottles, a change from the  22-ounce bottles the beer has historically been sold in.

The Bend, Ore.-based brewery has released an imperial barrel-aged version of Black Butte every year since its 20th anniversary in 2008, and the beer is based on its popular Black Butte porter (5.2 percent ABV.) The brewery was originally founded as a brewpub in 1998 and is named after the Deschutes River.

According to the TTB and Deschutes’ 2020 release calendar, Black Butte XXXII will be packaged in 12-ounce bottles that are scheduled to ship to retailers across the brewery’s entire distribution network in June.
