Large and detailed plan of the 1855 Bordeaux wine classification.

The Bordeaux Wine Official Classification of 1855 resulted from the 1855 Exposition Universelle de Paris, when Emperor Napoleon III requested a classification system for France's best Bordeaux wines which were to be on display for visitors from around the world. Brokers from the wine industry ranked the wines according to a château's reputation and trading price, which at that time was directly related to quality.

The wines were ranked in importance from first to fifth growths (crus). All of the red wines that made it on the list came from the Médoc region except for one: Château Haut-Brion from Graves. The white wines, then of much less importance than red wine, were limited to the sweet varieties of Sauternes and Barsac and were ranked only from first great growth to second growth.

A note to the right of the plan reads: (trans.) "This map is a reduction of the one used at the General Exhibition of 1855 by the Bordeaux Chamber of Commerce; it is drawn by the same surveyor". The surveyor in question was Unal Serres, a local cartographer, whose other known works include a plan of Bordeaux. Serres has dedicated the map to Mr Duffour Dubergier, the head of the Bordeaux Chamber of Commerce, who on 5th April 1855, had ordered the official classification of Bordeaux wines.

To the upper right are inset plans of the Medoc region with chateaux's marked, and coloured by 'crus', together with vignette views of Chateau Lafite, and Chateau Margaux. Below is an inset plan of the white wine region, together with vignette view of Chateau d'Yquem. To the lower right is a key to the crus, with the price range of each marked. To the lower left is a table of crus with their names, regions, and owners listed.
