Above Pfaffenheim, the vineyards face east and south-east, rising from about 210 to 320 metres. Clay and silt form part of this landscape, with limestone on Grand Cru Steinert and pink sandstone on Steinstück. The domaine also works with Grand Cru Zinnkoepflé, bringing these Alsace places into its wines.
Conversion to organic farming began in 2012, and the estate is now certified organic. For the brothers, this work serves a search for finesse, minerality and a more authentic taste. It also looks ahead: their ambition is to pass the land on intact, so that the next generation can continue its story.
