Together with the UIVV and Françoise Vannier Petit, we studied the 6 terroirs of Marsannay Clos du Roy, Clos de Jeu, Les Favières, Les Echezots, Les Longeroies and Les Champs Perdrix. This study showed us the richness and diversity of these Climats and allowed us to improve the adequation between grape variety and terroir which are expressed in our wines.
