This past April Wynkoop Brewing Company released a video (see below) claiming that they were brewing a beer with fermented bull testicles. People got excited. Wynkoop admitted it was an April Fool’s Day prank, but were nonetheless intrigued by the possibility of such a beer. Today, Wynkoop will tap the first keg of a “brand new and immensely unique Wynkoop beer: Rocky Mountain Oyster Stout.”

As Wykoop states,”We’ve turned our joke into a reality.”

“We and our fans are still laughing. Very important, that laughing,” writes Wynkoop in its press release anticipating the first tapping of a Rocky Mountain Oyster Stout keg.

“The beer is made with Colorado-grown base malts, roasted barley, seven specialty malts (including special B and smoked malt) and Styrian Goldings hops,” writes Wynkoop. “The beer gets a small dose of sea salt, too.” Head brewer Andy Brown states, “It gives the beer an extra layer of Rocky Mountain oyster flavor… and additional texture.”

The eight-barrel batch includes of course 25 pounds of sliced bull testicles, roasted by Wynkoop sous chef Andrew Langlo before being added to the beer’s mash. Delightful. But why the bull testicles? As Wynkoop observes, “Rocky Mountain Oysters (aka fried bull testicles) are arguably our state’s most popular local dish.”

And for the statistics-minded, Wynkoop states, “The beer is 7% ABV and has 3 BPBs. That’s balls per barrel.”
