Domaine Marcel Deiss is located in Bergheim in the heart of the Alsatian wine region. It is currently run by Jean-Michel Deiss, whose family has been making wine since 1744.

Domaine Marcel Deiss's wines are without doubt amongst the most exciting of the region, and the man himself is legend for his unconventional and innovative ideologies. The domaine has long focused on field blends, to produce wines which reflect the terroir on which they are grown more than the individual grape variety, and in doing so Deiss has forced changes on a region which was known only for varietal wines thirty years ago.

The wines from the original vineyards are all certified organic and biodynamic, but as the domaine has expanded from 27 hectares to 40, some of the newer vineyards have not yet achieved certification, though they are all farmed the same. All of the wines from the domaine are produced from within the Ribeauvillé fault area. This oval shaped area runs for about 15 kilometres between Rorschwihr and Kientzheim and is at its widest point at Bergheim where it measures 2 kilometres across. The Bergheim valley is unique in Alsace: a hill blocks the cold air flowing down from the Vosges which makes this valley warmer than the other Grand Cru valleys in the area. The terroirs are a patchwork quilt created by the various North-South and East-West faults. As such, Jean-Michel treats each parcel of vines separately starting from decisions on viticultural techniques to the actual vinification – a very long, careful and laborious process.
