Portland, Oregon-based Widmer Brothers Brewing has released the sixth beer in its limited-edition Brothers’ Reserve series, Kill Devil Brown Ale. A Caribbean-inspired offering, Kill Devil is brewed with palm sugar and molasses, and then aged in rum barrels from Puerto Rico’s Destilería Serrallés.

The 9.5%-abv brew will be available on draft and in 22-ounce bottles at select retailers, with a suggested retail price of $13.99 a bottle. According to Widmer Brothers, Devil Kill is “the most limited release of the Brothers’ Reserve beers to date.” Widmer Brothers Brewing is part of the Craft Brew Alliance, which was formed through the merger of Widmer and Seattle’s Redhook Brewing in 2008.
