Although the 550 hectares of the small wine region Nahe make up only a small share of the VDP.Classified vineyards, they propose a broad geological spectrum. The vineyards spread from the southern edge of the Rhenish Massif to the Alsenz and Glan side valleys of the Nahe River. In the lower Nahe between Wallhausen and Bingerbrück, Devon rocks like phyllite, green schist and quartzite are found. Upper Rotliegend sandstone comprises the subsoil of the great part of the Nahe region. Blue and red slate determine the soils around Monzingen. Between Bad Münster and Schlossböckelheim weathered volcanic soils dominate. The region is relatively cool, but many vineyards have a significantly warmer microclimate due to their aspect, protected locations or proximity to the Nahe River.
A vineyard classification existed on the Nahe over one hundred years ago in the form of land parcel categories for property taxes. The results are illustrated in the Nahe Vineyard Map for the Administrative District Coblenz dating 1901.
