The soils of the Côte de Beaune are covered with limestone scree coming from the top of the hill, red silts deposited in the glacial era, and rocks resulting from the alteration of the underlying geological strata. Brown limestone and stony soils characterise the southern part of the Côte d'Or. At the top of slope, the soils are lean, very limestone, they enrich themselves in clay going down. There are three different hillsides: those of the Corton mountain, those of the Côte des Blancs and those of Chassagne, Santenay and Maranges.
