As an April Fools joke, Wynkoop Brewing Company out of Denver, Colorado made a video that claimed they were working on a beer that would feature an ingredient that’s famous in the Colorado area: Rocky Mountain Oysters, also known as fried bull testicles.
Apparently the response to the idea was so strong that they decided to do it for real, and are now actually working on a Rocky Mountain Oyster Stout, which they will serve at their brewery, and at the Great American Beer Festival.
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, which, according to head brewer Andy Brown, “gives the beer an extra layer of Rocky Mountain oyster flavor 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.
The resulting beer is 7% ABV, and has 3 BPBs. (Balls Per Barrel)
So how does it taste?
According to Wynkoop, 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.
You’ve got to give them credit though, because it definitely takes balls to brew a beer like that.
