Since 1984 Château Rieussec has been the Sauternes property of the Rothschild family, owners of Chateau Lafite. Rieussec, a neighbour of Chateau d’Yquem, had for generations been a leading producer and was ranked Premier Cru in 1855. Even so, under Rothschild ownership the property has been transformed, with new cellars and winery and far more rigorous grape selection (plus greater use of barrel fermentation and maturation) for the flagship Grand Vin. This has led to Rieussec’s clear emergence as a rival to its famous neighbour. Chateau Rieussec is 90% Semillon, with minor contributions from Sauvignon Blanc and Muscadelle. The property is 110ha with 68ha under vine.
