Château d`Yquem 1983 is a mature-vintage noble sweet wine produced in the Sauternes appellation of Bordeaux. Located in the heart of the Sauternes appellation on Bordeaux`s Left Bank, Yquem is the most prestigious producer of sweet wines in the world, and the only Sauternes producer to be granted the status of `Premier Cru Supérieur`. The estate vineyard is planted mostly Sémillon, with a smaller proportion of Sauvignon Blanc, as reflected in the wine`s blend. Harvest can involve up to 200 workers, who may pass through the vineyard up to 10 times to pick only those berries that have been infected with `noble rot`, the fungus which shrivels and dehydrates the grape berries, concentrating their sugars. 1983 is among the greatest vintages of Yquem.
