For over 20 years, Domaine Mittnacht Frères has been committed to Organic and Biodynamic Agriculture. They respect the natural cycle of the vines and their soil. The vineyard is certified both Ecocert and Demeter. Their approach involves avoiding synthetic chemicals such as herbicides, fertilizers, and insecticides. Instead, they allow the natural flora and fauna in the vineyards to thrive. They create their own compost and use specific biodynamic preparations tailored to the plant’s needs. This holistic approach ensures healthy products, allows the vines to defend themselves naturally, and preserves the unique terroirs of the Alsace Appellation d’Origine Protégée.

The biodynamic calendar guides their work in the vineyard and cellar. Different days are associated with specific activities: root days, fruit days, and key wine-related processes (such as racking and bottling). Tisanes and decoctions of plants like nettle, willow, and horsetail are used in conjunction with minimal doses of Bordeaux mixture or sulfur flowers.
