The cultivation area with a vineyard of 557 hectares lies in the federal state Rheinland-Pfalz in Germany, Historically, viticulture is traced back to the Franks from the 8th century. The cultivation area is after a western tributary of the Rhine named. The Ahr rises in the Eifel and flows south of Bonn in the Rhine. The vineyards are located on south facing steep slopes in the lower and middle part of the deeply cut river valley over a length of about 25 kilometers. In the upper region between Altenahr and Marienthal, slate weathering prevails in the narrow valley areas. In this narrow valley, the vineyards reach almost to the river. In the lower region between Walporzheim and Heimersheim loess clay soils prevail, which are offset by stone weathering.
