According to labels filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), Sierra Nevada Brewing Co. is working on releasing Barrel-Aged Coconut Lime Ale, an 8.4 percent ABV ale aged in rum barrels with coconut and lime that will be packaged in 750ml bottles.

The new beer will be an exclusive release for the Chico, Calif.-based brewery’s 2019 Alpha Hop Society, a membership club that gives members access to exclusive beers, the first shot at new beer releases and access to Sierra Nevada brewery events.

Past Alpha Hop Society releases have included Barrel-Aged White Ale with Cherries, a 9.5 percent ABV witbier style ale aged in bourbon barrels with cherry puree added and Barrel-Aged Orange Currant Imperial Stout, an 11.7 percent imperial stout aged in bourbon barrels with red currants and orange peel.

An email sent to the brewery for additional information was not immediately returned .
