Bonnes Mares is a 15-hectare Grand Cru climat that straddles the border of Chambolle-Musigny (where 13.5 ha are located ) and Morey-St-Denis (the remaining 1.5 ha). The vineyard is situated north of the village of Chambolle-Musigny, and borders the Route des Grands Crus in the east and Clos de Tart in the north. The east-facing vineyard lies on a very gentle slope that varies only between 265 and 300 meters in elevation. Bonnes Mares is bifurcated geologically, with the northern half (the Morey side) – called terres rouges — comprised of heavier soil with a larger component of clay; and the southern half – called terres blanches — comprised of lighter soil, with a greater concentration of rocks and limestone, and containing an abundance of fossilized seashells. The wines coming from the two sections differ considerably, with terres rouges producing more robust and sturdy wines, while the terres blanches wines more delicate and elegant. In either case, as Clive Coates has written, the wines are hardly Chambolle-Musigny. Instead Bonnes-Mares is sui generis: wine that is fully-textured, deep, tannic and rich.
The name Bonnes-Mares likely derives from a cloistered order of Cistercian nuns (the good mothers) that lived nearby. A more charming etymology suggests that the name derives from a now-lost bas relief unearthed that portrayed a trinity of Roman goddesses of the harvest whose images protected the vineyard.
