Despite names like Fat Spider Ale, Turkey Stout and Black Kitty Brown, only one BYO recipe has ever featured animals as an ingredient — Black Pearl Oyster Stout. We’ve been lucky enough to taste this beer, brewed by Joe Walton and Jim Michalk, and it’s delicious. The beer has a complex dark grain character and a slightly silky mouthfeel. There’s no strong oyster flavor, but you may detect a slight salty/briney character. For best results, use hard water with a moderate to high level of carbonates.
