Relief and soils

The Klosterberg is situated on a slope facing towards the Zornheim Berg and looks over the Selz valley. The vineyard site is characterised by limestone and Rendzina, which formed from tertiary marine deposits in connection with a limestone reef. The soil is shallow to medium-depth, very calcareous and stony-sandy-loamy. It has low water storage capacity that is available to plants, good aeration and heat retention, as well as limited rooting depth.

History
The name Klosterberg is traced back to the settlement of a monastery in Mainz. Nieder-Olm belonged to the Prince-Archbishopric of Mainz from the early Middle Ages.
