Fans of Deschutes Brewery’s annual anniversary beer now have a date to mark on their calendars: June 27.

According to the Bend, Ore.-based brewery, that is the day that its Black Butte XXVII imperial porter (11 percent ABV, 60 IBUs) will be released to the public. As with previous versions, the beer is brewed with pale, wheat, midnight wheat, chocolate and crystal malts along with millennium, cascade, and US Tettnang hops. In addition, the imperial porter incorporates cocoa nibs from Seattle-based Theo Chocolate, rose water, apricot puree, and pomegranate molasses before being aged in bourbon barrels for six months. The resulting concoction is then blended with non-bourbon barrel-aged version at a 1:1 ratio before being packaged in 22-ounce bottles.

Deschutes 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 Deschutes, Black Butte XXVII will be available in “limited quantities” packaged in 22-ounce bottles starting on June 27 across the brewery’s entire distribution footprint.
