The Chateau d'Yquem is an area of 133 hectares including 113 hectares of vineyards, 102 acres operated, south of Bordeaux in Sauternes region that produces a sweet white wine ranked Premier Cru Superior, the only wine from the Sauternes category. It is considered by many as the best Sauternes. The yield is only 6 hectoliters per hectare and in some years, if the quality is not deemed sufficient, the bottles are not sold under this label. In autumn, morning mists and sunny afternoons allow the noble rot to develop. The harvest is extended over a long period of time during which the grapes are harvested by hand, individually. . The wines are characterized by their complexity due to a significant amount of residual sugar and flavorings made by Botrytis cinerea. A relatively high acidity helps offset the sweetness. Another characteristic for which Château d'Yquem is known is his longevity. In good years does present a bottle of his outstanding after one or two decades in a cellar and with care it will keep for a century or more, adding to the complexity... Since 1959 Chateau d'Yquem produces a dry white wine named "Y" (and before 2004 "Y Lur-Saluces") makes an equal proportion of Semillon and Sauvignon Blanc. This wine, like great wine is not produced every year. The 2005 vintage was the first vintage of Yquem offered for sale en primeur. .
