The winery is located in the municipality of Escherndorf (Maindreieck area) in the German Franconian wine region. It was built from 1979 on by Helga and Rainer Sauer. After one year of practical training in California and studies in Geisenheim, Daniel Sauer (son), graduate oenologist, is responsible for the cellar. The vineyards comprise 15 hectares of vineyards in the individual locations Fürstenberg and Lump (Escherndorf) as well as Sonnenberg (Untereisenheim). They are planted with the white wine varieties Silvaner (60% of the area), Müller-Thurgau (20%), Riesling, Traminer, Kerner andPinot Blanc, as well as the red wine varietiesPinot Noir, Domina and Blauer Portugieser. A part of the area (4 ha) is cultivated biodynamically.
Only physiologically ripe and healthy grapes are processed by selective hand harvesting. Botrytised berries are completely sorted out for the dry aged wines. In order to preserve the typical character of the variety, the processing is carried out very gently without pumping. The wines are stored on the fine yeast for a long time. Depending on the type of wine, the wines mature in stainless steel, in large wooden barrels or in concrete. The wines are marketed according to the four-stage VDP classification model. The great wines receive the designation "Escherndorf am Lumpen 1655". As a speciality, the Silvaner "ab ovo" is aged in a 900-litre concrete plant. Another premium wine is the Silvaner "L". About 135,000 bottles of wine are produced annually. The winery is a member of the VDP (Verband deutscher Prädikatsweingüter) and Frank & Frei.
