Château Palmer is a Troisième Cru Classé estate in the commune of Margaux.  Originally the vineyards were part of the d'Issan estate, but became known as Château de Gasq when they were purchased by the family of the same name.  The estate acquired its modern name in 1814, when it was bought by the English general, Charles Palmer, on his way back from the Peninsular War where he had fought with Wellington against Napoleon.  Palmer eventually died bankrupt, having spent his wealth on his vines!

In 1938, the Sichel family joined forces with a group of wine merchant friends to purchase the property (originally including the Ginestet and Miailhe families).  Today, the majority shareholders of Sichel and Mahler-Besse, with a number of other minority shareholders.

The vineyard is 52 hectares of 'croupes' (knolls) of Garonne gravel, planted to 47% Cabernet Sauvignon, 47% Merlot and 6% Petit Verdot.  Thomas Duroux, formerly winemaker at Tenuta Dell'Ornellaia, has been in charge since 2004.  The estate is run biodynamically. 

The second wine, Alter Ego de Palmer, has become increasingly serious in recent years, so much so that in fact Palmer now sees this as not a second wine as such, but as a wine in its own right, with the grapes coming from a dedicated vineyard.
