Château Palmer is a winery in the Margaux appellation. The wine was classified as one of fourteen Troisièmes Crus (Third Growths) in the historic Bordeaux Wine Official Classification of 1855.
The property is situated in the communes Margaux and Cantenac, and its wine is considered to be one of the two most popular Third Growths.
Since 1998, the château has been producing also a second label, not a second wine, Alter Ego de Palmer, selected from the same quality terroir, but employing different wine-making techniques and different proportions of grapes in order to produce an earlier-drinking wine. The result has been a significant reduction in the quantity of wine sold as Château Palmer (from nearly 20,000 cases before the introduction of Alter Ego de Palmer to 11,000-12,000 cases currently).
The second wine, La Réserve de Général, is not a component of Alter Ego de Palmer, but is now sold off in bulk.
