The Turmberg name refers to the surviving keep of what was once Scharfenstein Castle. Built around 1160, the hilltop fortress sits a full 240 meters above sea level on a hillside spur to the northeast of Kiedrich. It was intended by the region's territorial rulers to secure the Rheingau's eastern flank, as well as an important trading route.

The German Wine Act of 1971 merged the old Turmberg site designation into the Kiedrich Wasseros site. In 2005, however, Weingut Robert Weil re-applied the moniker for its monopole.

The Turmberg lies on the face of a steep mountain spur. The soils on this slatey crag are mostly comprised of stony fragmented phyllite interspersed with loess and loam.

The wines from this vineyard show a sophisticated, almost gossamer minerality.
