American craft brewers draw inspiration from just about every world brewing tradition, and then sometimes re-create them in their own image with boatloads of hops, barrel-aging, or a momentary whim. Other times, brewers strive for strict historical re-recreations in an effort to place themselves in another time and place. In recent years, we've seen a domestic resurgence of many styles, including a few tart German brews — notably Berlinerweisse and Gose. To that list, we can add another, even more obscure style: Gratzer.
