There are a number of classifications of Bordeaux wines, covering different regions. None of these attempts to be a comprehensive classification of all the producers within a given area: rather, only the producers (universally known as châteaux, although not usually possessing the architectural grandeur that might imply) perceived as being of an unusually high standard are included in the classification.
The châteaux included in the classification are referred to as classed or classé, and those not included are referred to as unclassed. Some classifications sub-divide the classed châteaux, according to the perceived quality. On the Left Bank, the Bordeaux Wine Official Classification of 1855 is the starting point for classification. Although this purports to be a classification of all Bordeaux wine, it in fact exclusively lists red wine producers from the Haut-Médoc plus Château Haut-Brion of Graves, and (in a separate list) sweet white wine producers from Sauternes (including Barsac).
Estates in the Médoc which were not classified in that listing may be classified under the Cru Bourgeois label. In 1953, a Classification of Graves wine was produced. Although this purports to classify the whole of Graves, it exclusively lists châteaux in Pessac-Léognan. In 1954, a separate classification of Saint-Émilion wine was set up for this Right Bank region.
