single vineyard in the municipality of Rüdesheim on the Rüdesheimer Berg in the German wine-growing region of Rheingau. The name refers to Ehrenfels Castle, built in 1211; the vineyards were established around the same time. These were owned by the Electorate of Mainz for a long time. The ruins of the castle, destroyed in 1689, offer a unique vantage point on the bend in the Rhine known as the "Binger Loch" after a laborious climb through the steep terraces. From here, the four wine-growing regions of the Middle Rhine, Nahe, Rheingau and Rheinhessen are in view. Until the end of the 1960s, the terraces, which used to be extremely narrow and steep, could only be cultivated with laborious manual labour. Between 1970 and 1985, a land consolidation took place, during which roads were laid out and larger areas were created between extensive terrace walls.
