Single location in the municipality of Ahrweiler in the German Ahr wine growing region. To the east is the Forstberg site, to the west the Silberberg site. The name either goes back to a former plantation with wild roses, or is derived from "Runst" (running water), which refers to a spring that was once located there. The steep vineyards, facing south-west to south-east at an altitude of 110 to 180 metres above sea level, cover 50 hectares of vineyards, only half of which are planted. The diverse soils consist of greywacke in the eastern part, and loam, loess and loess-clay in the western part. Here 70%Pinot Noir (Pinot Noir), as well as Blauer Portugieser, Frühburgunder, Dornfelder, Grauburgunder(Pinot Gris), Müller-Thurgau and Riesling are cultivated. Members of the winegrowers' cooperatives Ahrweiler Winzer-Verein eG and Ahr Winzer eG, as well as the vineyards Adeneuer, Bertram Julia, Heiner & Kreuzberg, Jean Stodden, Kreuzberg, Kriechel Peter, Lingen Peter, Maibachfarm, Sermann-Kreuzberg and Weingut Sonnenberg have shares in the vineyard.
