Hallertau (US) is definitely a tenacious, Bavarian-style hop. It long dominated its heritage region and is still in demand by craft brewers for Bavarian-style ales. As an American hop, it is outperformed by Mt. Hood and Liberty but is still holding its own. Its low alpha acids and high humulene contribute to a mild, flowery and delicately spicy aroma and flavor profile. The original German-grown Hallertau has long been the staple of German and European lagers.
