The Wynkoop Brewing Company is making a ballsy move by offering its limited-edition bull testicle beer nationwide.

Fox News reports the brew is called Rocky Mountain Oyster Stout. It's made of organic Colorado malts, hops, Rocky Mountain water and bull testicles from free range Colorado cattle. According to brew masters, the recipe yields a creamy stout that delivers loads of flavors like roasted barley, coffee, chocolate and nuts. The Rocky Mountain Oyster Stout will be available in two-packs this month through beerjobber.com.
