Château Simon has been owned by the Dufour family since 1814, with traditional wine-making expertise being passed down from generation to generation. Over time, the property has grown gradually and today oversees 38 hectares of its own vineyards, encompassing the appellations of Bordeaux, Graves and Barsac-Sauternes respectively. Grapes for the Sauternes are sourced from 12 hectares of vineyard in the clay-chalk soils of Haut-Barsac and a further 6 hectares of deep gravel soils. From the great 2009 Sauternes vintage, this is a blend of 90% Sémillon, 8% Sauvignon Blanc and 2% Muscadelle. All grapes are hand-picked over four to five successive gatherings, or 'tries', each one selecting only over-ripe grapes effected by noble-rot. After fermentation of individual wines in barrel, the best vats are selected and blended before lying in oak barrels for 12 months prior to being bottled at the chateau.
