Alesmith Brewing Co. is adding a new Speedway Stout variant to the mix that features double the barrel-aging.

Double Barrel Speedway Stout is a 13 percent ABV imperial stout brewed with coffee that has been aged in both bourbon barrels and Portuguese port barrels for an “extended aging period.”  The new beer is one of more than 60 variants that uses Alesmith’s Speedway Stout as its base, and represents the first time that the stout has been aged in port barrels.

According to a post on Alesmith’s Eventbrite page, customers will be able to purchase up to two 750ml bottles of Double Barrel Speedway Stout ($35) starting on Aug. 14, with bottle pickups available at the brewery starting on Aug. 19. In addition, there will be no proxies allowed.
