Wynkoop Brewing Company’s Ballsy Beer

By Kirby Bennett

What started as an April Fools’ Day prank has now become a reality, for better or worse. As a practical joke, Wynkoop Brewing Company, in Denver, Colo., released a video last April announcing the release of a new beer brewed with “one of Colorado’s unique culinary jewels,” a euphemism for bovine testicles, sometimes referred to as Rocky Mountain oysters. The idea was too ‘nutty’ to pass up, and Wynkoop will be releasing its Rocky Mountain Oyster Stout on Monday October 8 at 5pm.

Eating animal genitalia dates back to Roman times, is believed to be a source of virility, and in parts of Asia it’s also considered an aphrodisiac. Rocky Mountain oysters, a.k.a. prairie oysters, are typically peeled, rolled in flour and spices, and then fried. In Spain, Argentina, and parts of Mexico, the organs are called “criadillas” and prepared a variety of different ways.

Wynkoop describes this joke turned reality: The beer is a meaty foreign-style stout brewed with loads of dark malts, specialty grains and freshly sliced and roasted bull testicles. A special ultra-limited-release beer, it weighs in at 7% ABV and three BPB (balls per barrel).

Rocky Mountain Oyster Stout will be available only at the brewpub and at the Wynkoop booth at the Great American Beer Festival.
