Facing the east, Steinert, to the south of the Pfaffenheim boundary, is the steepest vineyard in the municipality. Its soil is dry and porous and most limestone. It forms a homogeneous terroir from the Oolithic Dogger era covered by boulders that flow downstream, like stones, hence the name Steinert.
The geographical background heavily influenced the grape varieties and the growing-method of this locality of 34.90ha where it was necessary to use a rootstock, highly-resistant to active limestone and drought, therefore, not very vigorous. Considering these factors, Gewurztraminer, Pinot Gris and Riesling are the major varieties in Steinert.
Since 1150, the Benedictine convent of Muri (Switzerland), the Roman Catholic Diocese of Basel and Strasbourg owned the vineyards in this area called Steinert. These wines were served to the pilgrims and bishops of the communities.
Steinert wine is characterised by very developed aromas, especially after ageing.
