The Côte de Beaune area is the southern part of the Côte d'Or, the limestone ridge that is home to the great names of Burgundy wine. The Côte de Beaune starts between Nuits-Saint-Georges and Beaune, and extends southwards for about 25 km to the river Dheune. The trend of producing red wines continues from the Côte de Nuits to the north, down through Beaune, although the wines become lighter and more perfumed. Farther south lie the great names of white Burgundy such as Meursault and Chassagne-Montrachet. The far south of the district sees a return to red wines in Santenay that continues across the Dheune into the Côte Chalonnaise. This mix of Pinot noir and Chardonnay grapes reflects geology in the southern Côte d'Or that is more variable than in the north.
