Chanson is one of the major owners of Clos des Mouches with a vineyard of 4.5 hectares. This is a sunny terroir which benefits from an ideal location on the hill at the southern end of the vineyards of Beaune on a spur pointing towards Pommard. A plot of 2 hectares on the upper side of the hill is planted with Chardonnay on a limestone subsoil covered with sand.
