The Brunnenhäuschen site is situated east of Morstein and above the Steingrube site. Due to its altitude, grapes ripen slowly and harvesting usually takes place after a very long growing season. The finest portion of Brunnenhäuschen is in the old parcel known as “Abtserde.” We cultivate half a hectare (1.2 acres) of Riesling here.

This site is marked by clayish marl that is rich in limestone. Due to a high iron oxide content, parts of the soil are reddish in color, also referred to as “terra rossa.”
The subsoil is interspersed with large limestone rocks.
