A new beer being released by Firestone Walker Brewing Co. is conditioned on fruit from halfway around the world.

UnderCurrants is a 6.3 percent ABV wild ale fermented with 1.5 pounds per gallon of black currants sourced from Poland for four months in French oak foeders. The fruit was frozen with IQF (individually quick frozen) technology “to perfectly preserve their fresh aromas and flavors” of the fruit before being shipped to Firestone Walker.

The new ale uses the Buellton, Calif.-based brewery’s Agrestic Ale as its base, an American wild red ale that debuted in 2014.

Started in 2006 as a way for brewers to experiment, the Barrelworks program at Firestone Walker has released more than 15 different beers to date and constitutes more than 1,500 barrels in a 7,000-square-foot building in Buellton, Calif.

According to a post on Firestone Walker’s Barrelworks Facebook page, UnderCurrants is packaged in 375ml bottles ($14.99) and will have no purchase limit when it is released at the brewery today. There will be 2,900 cases available and some bottles will see “limited” distribution across Firestone Walker’s entire distribution network.
