They have five hectares planted over two distinct areas. Both areas were certified biodynamic in the 1980s (since before their vineyards were planted). They ferment with wild yeasts, and use just a small amount of French oak.

Here is what they have to say about the importance of biodynamic farming:
"Our approach to both the growing and the making of the wine is traditional-- doing much in the vineyard by hand and being as least interventionalist in the winemaking as possible. We respect biodynamics as a sensitivity to the rhythms of nature, the health of the soil and the connection between plant, animal and cosmos. It is our inherent belief that only through the practice of biodynamics can we allow the vineyard to reach its potential."
