German Vixen Hill "Pilsner" Lager. Fuchsin (Vixen), hügeln (Hills). In this experiment we are using wild growing hops without knowing the variety of the hops. To be on a conservative side I am adjusting IBU to the lower end by using Saaz as the template. If they are of higher a bitterness than we could end up with a pilsner on the higher bitterness scale or an APA style if bitterness is really out there.
