Single location in the municipality of Escherndorf (Maindreieck area) in the German production area of Franken. In 1688, the site "Am Lumpen" was less than one hectare in size. Today's size was achieved by adding the three sites Bergsteig, Katzensteig and Oelgrube in 1912, as well as further changes during the land consolidation in 1970. The name most likely derives from the poor appearance that this slope, always threatened by erosion, used to offer after heavy rainfall. The very steep vineyards facing the Main River from southeast to south-southwest at an altitude of 190 to 270 meters above sea level, with a slope gradient of 40 to 75%, extend in a wide arc around the community of Escherndorf. They comprise 37 hectares of vineyards on shell limestone soils with deposits of Lettenkeuper and loess loam layers in the western part.
