Steinberg is a 32.4 hectares (80 acres) wall-enclosed vineyard (a Clos, using French terminology) near Hattenheim in the Rheingau.[1][2] It is the largest wall-enclosed vineyard in Germany.
Steinberg is one of handful single vineyard sites in Germany which for reasons of historical significance have dispensation from having to include a village name together with the vineyard's name, so the wines from Steinberg are simply labelled Steinberger.
The vineyard belongs to the government-owned Hessische Staatsweingüter (Hessian State Wineries) and is today planted with only Riesling vines.
