Classifications of wineries(châteaux) or wines in Bordeaux were already made in the 18th century. Today there are five systems; the most famous dates back to 1855, but only wines from the left bank(Rive gauche) of the Gironde were taken into account, including the Médoc, Graves and Sauternes areas. Of course, excellent wines also grow on the right bank(Rive droite), such as Fronsac, Pomerol and Saint-Émilion. The classification, which is more than a century and a half old, applies regardless of the quality of the wines, which certainly varies from year to year. Up to now there has been only one change as an absolute exception, in which Château Mouton-Rothschild rose from 2nd to 1st place. It is still of great importance and is therefore used by the wineries for marketing purposes, with the rank being indicated on the label.
