Flying Buffalo BA German Chocolate Cake Griffin Claw Brewing is a Russian imperial Stout by style. How does one make a German Chocolate Cake? First you brew a big Russian Imperial Stout and age it for 9 months in bourbon barrels. That gives you a solid base to add the special ingredients, rich German chocolate, Tahitian vanilla, toasted coconut, and lactose milk sugar. The result is a rich, liquid cake of German style with boozy vanilla notes up front, profound chocolate throughout and a decadent sweet cessation to devour in bliss. This craft beer is 12% ABV. In this craft beer review, we will take a look at the color, smell, and taste.
