David religiously stands for biodynamic farming in Champagne, winery is certified as biodynamic since 2000. His first wine in the line-up, L'Amateur, is vinified using local yeasts in enamelled steel tanks, as he believes stainless steel lends negative energy to his wines. On the contrary, the rest of his cuvees are wholly or partly fermented in wooden barrels bought from Domaine Leflaive in Burgundy.
