Château Palmer is a winery in the Margaux appelation of the Bordeaux region. It is classifed as one of the fourteen Troisièmes Grand Cru Classé. It is considered one of the most popular Third Growths. The vineyard extends 55 hectares, planted with 47% Cabernet Sauvignon, 47% Merlot and 6% Petit Verdot. Annual production is about 12,000 cases. Since 2004 the enigmatic oenologist, Thomas Duroux, has led the winemaking team, undertaking major renovations with a focus on biodynamics. 2014 saw the first vintage released from 100% biodynamic grapes and no preservatives during vinification and the estate is lauded for spearheading the movement.
