Steep cliffs of extrusive igneous rock (porphyry and melaphyre) rise directly from the banks of the River Nahe between Norheim and Niederhausen. Between those cliffs are small hollows, known in the local dialect as “Dellchen”. The slate soils here are mixed with the stony precipitate sedimentary rock of the adjacent volcanic cliffs. The extremely steep, perfectly south-facing slope is terraced by dry stone walls that demand a rigorous level of labor-intensive care. Protected by the surrounding cliffs, the Riesling grapes enjoy an extremely long hang time and year for year achieve perfect levels of ripeness.
