I read about this and couldn’t believe it until I went to the Wynkoop Brewery website.

On October 8, at 5 PM, Wynkoop Brewing Company will tap the first keg of a brand new and immensely unique Wynkoop beer: Rocky Mountain Oyster Stout. Yes, the beer was inspired by our April Fools spoof video this spring, in which we claimed to have released a beer made with bull testicles. The beer is made with Colorado-grown base malts, roasted barley, seven specialty malts (including special B and smoked malt) and Styrian Goldings hops. The beer gets a small dose of sea salt, too. “It gives the beer an extra layer of Rocky Mountain oyster flavor,” brewer Andy Brown notes, “and additional texture.”

The 8-barrel batch also included 25 pounds of bull testicles that were sliced by hand and then roasted (by Wynkoop sous chef Andrew Langlo) before being added to the beer’s mash. So how does it taste? Rocky Mountain Oyster Stout is an assertive foreign-style stout, slightly viscous, with a deep brown color. It has equally deep flavors of chocolate syrup, Kahlua, and espresso, along with a palpable level of alcohol and a savory umami-like note. It finishes dry and roasted with a fast-fading hop bite. The beer is 7% ABV.
