Once belonging to the Carmelite monks in Langon, Château Rieussec is now owned by Domaines Barons de Rothschild (Lafite), since they purchased the estate in 1984. The vineyard of Rieussec borders Fargues and Sauternes, and adjoins Château d’Yquem. Rieussec is one of the largest properties in Sauternes and Barsac, covering 93 hectares of gravelly soil layered with alluvial deposits.

The iconic grape variety of Sauternes, Sémillon, dominates (90%), followed by Sauvignon (7%) and Muscadelle (3%). Traditional Sauternes techniques are used and the harvests are carried out with selective pickings depending on the ripeness of the grapes and evolution of botrytis. Harvest lasts for 6 to 8 weeks from September to November. Each vintage ages in oak barrels. The length of ageing in barrels varies from 16 to 26 months, during which the wines are periodically racked. The wines are bottled at the Château.

A new cellar was built in 1989 to extend the ageing period in barrels. The quantities of the Grand Vin that were produced were much reduced in the 1990’s due to more meticulous selection, to the point that none at all was produced in 1993 (this was also the case in 1977 and again in 2012).

The vineyard is managed by Eric Kohler, Technical Director of the Bordeaux Châteaux, with the help of Jean de Roquefeuil, Vineyard Manager, and Serge Lagardère, Cellar Master.
