With an inclination of 70%, Rüdesheimer Berg Schlossberg is the steepest vineyard in the Rheingau. Its name derives from the Ehrenfels castle ruins. The vineyards on the "Rüdesheimer Berg" - the steep slopes adjacent to Rüdesheim - particularly the protected Schlossberg site, benefit from intense solar radiation. The slate and Taunus quartzite soils absorb heat during the day and gently release it at night.
