When Wynkoop Brewing decided to pull a prank on April Fools Day,  they had no idea that fans of the company would be begging for the real thing.  Rocky Mountain Oyster Stout was meant to be just an April Fools Day joke, but when fans saw the video, it was clear that this prank would soon become a reality.

Check out the original video posted as on April Fools Day joke:

Wynkoop Brewing Company, hailing from Denver, Colo., reports that Rocky Mountain Oyster Stout uses the real thing in the brewing process. Fried bull testicles also known as Rocky Mountain Oysters is the delicacy that serves as the inspiration. What started off as a joke became so hugely popular among fans of idea that the beer soon turned into a reality. On October 8, the brewery tapped the first keg of Rocky Mountain Oyster Beer and made it available to consumers.

According to the website, 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,” 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?  Wynkoop Brewing Company shares, "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 and has 3 BPBs. That’s balls per barrel.

The beer will be available exclusively at Wynkoop Brewing Company and at their table at the Great American Beer Festival, October 11-13 at the Colorado Convention Center  in Denver.

They are hoping that you'll go nuts for it.

Anyone attending the Beer Festival, must bring me a sample!
