Located in the valley of the river Ahr (a tributary of the Rhine river), Ahr is one of the smallest of Germany’s 13 wine regions. It is located within the federal state of Rhineland-Palatinate and is the world’s northernmost wine region with red wine grape production. The region is known particularly for its Pinot Noir (known in Germany as Spatburgunder) wines, as well as its Portugieser and Riesling wines.
