For the 1855 Paris Expo, Napoleon III requested a classification system for Bordeaux wines on display according to reputation and price. The resulting red wine classification, which still stands today, includes 60 châteaux from the Médoc (+1 Graves): graded into five growths or crus. For white wines, only sweet whites from Sauternes and Barsac were ranked.
Since 1855 there has only been one change to the classification - in 1973 Mouton Rothschild was elevated from a second to a first growth. Below the 1855 classification, you will find the 1959 Graves classification.
