The Côte d’Or is the most celebrated part of the Burgundy region in eastern France. The chain of hills called the Plateau de Langres which runs from north-east to south-west through the Côte d’Or department to the north of Dijon then continues south-westwards for 30 miles (50 km) south as the Côte-d’Or escarpment. The south-east facing slope of this escarpment is the site from which the most celebrated Burgundy vineyards are found. Hugh Johnson (Wine Companion: 1991, p.106) wonders whether ‘any other hillside could do what the Côte d’Or can, provide scraps of land and scattered episodes of wether that bring two grape varieties [Pinot noir, Chardonnay] to a perfection not found anywhere else.’
