Deschutes Brewery will be releasing a barrel-aged porter to celebrate its 32nd birthday, but this year’s version is in smaller bottles.

That beer is Black Butte XXXII, a 13.4 percent ABV imperial porter aged in Columbian rum barrels that incorporates cold brew coffee, vanilla beans, nutmeg and sweet orange peel.
While the porter has historically been sold in 22-ounce bottles, the newest incarnation of Deschutes birthday release will be packaged in four-packs of 12-ounce bottles.

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 a post on Deschutes’ website and an email sent to Tenemu, Black Butte XXXII packaged in four-packs of 12-ounce bottles that are available for purchase at the brewery now, while bottles will shipping to retailers across the brewery’s entire distribution network this month.
