Single location in the municipality of Erbach in the German Rheingau wine growing region. The name is probably derived from a purchase contract concluded with a deed, i.e. with "letter and seal". The south-facing vineyards at an altitude of 110 metres above sea level with a slope of 10 to 20% comprise 15 hectares of vineyard area. They are well protected from north and east winds and have excellent exposure (sunshine). The soils are composed of clay layers with a deep loess loam layer and a high percentage of fine earth. There is a good water supply. The Riesling variety in particular is cultivated here. The Eser August, Hessische Staatsweingüter, Jung Jakob, Oetinger and Schloss Reinhartshausen, for example, have their share of the site.
