Geisenheim is a town of approximately 11,500, located on the Rhine river between Rudesheim and Winkel in the Rheingau, Germany. It is the birthplace of Muller-Thurgau as well as several other lesser-known grape varieties originating from the Geisenheim Grape Breeding Institute.
There are seven individual vineyard sites in Geisenheim, but only Klauserweg is classified by the VDP as Erste Lage. It is located to the west of Johannisberg in south-facing loess, loam and clay soils. To the north, the Taunus mountains serve as a protective barrier against cold prevailing winds.
Although the grape-breeding institute continues to experiment with cross-breeding and vine improvement, Riesling is still the dominant variety grown in Geisenheim.
