Westbrook Brewing Co. and 3 Sons Brewing Co. have collaborated on a beer that combines one of each of the brewery’s best known creations.

Velvet Tuxedo is a 12 percent ABV imperial stout brewed with Chinook hops that is a combination of two beers: 3 Sons’ Summation, an imperial stout conditioned on coffee and vanilla; and Westbrook’s Mexican Cake, an imperial stout aged on cocoa nibs, vanilla beans, cinnamon sticks and fresh habanero peppers.

The stout was then aged on cocoa nibs and dried tart cherries for 22 months in Cabernet wine barrels before being bottled.

According to a post on Westbrook’s Facebook page, Velvet Tuxedo is packaged in 22-ounce bottles ($20) that are available at the brewery now.
