Jean-Claude's first experimentation with biodynamics was in his own backyard as young man. In 1979 he then decided to become a vigneron and took over his family holdings converting it to biodynamics. As a result, he was the first wine grower in Burgundy to work under bio principles. His walled vineyard “Clos des Mariages” is the first and therefore oldest biodynamic parcel of vines in all of the Cote d’Or.
