The Cote de Beaune covers about 30 km running from the northern limit of the AOC Ladoix to the southern limit of the AOC Maranges, although the latter designation is all outside the administrative department of the Cote d'Or, belonging instead to that of Saone-et-Loire. In the Cote de Beaune, the strip of rock outcrop, or Argovien, is situated higher up the hill; instead of a narrow strip of vineyard below the ledge, therefore, a broad, gentle slope has been formed on which the vineyards climb, some almost to the peaks.
