MÉDOC, a district in France adjoining the left bank of the Gironde from Blanquefort (N. of Bordeaux) to the mouth of the Gironde. Its length is about 50 m., its breadth averages between 6 and 7 m. It is formed by a number of low hills, which separate the Landes from the Gironde, and is traversed only by small streams; the Gironde itself is muddy, and often enveloped in fog, and the region as a whole is far from picturesque. Large areas of its soil are occupied by vineyards, the products of which form the finest growths of Bordeaux. (See Wine.)
