The Domaine de Léoville, one of the oldest estates in the Medoc, belonged to some of the richest and most influential French noble families. Château Léoville-las-Cases has been run by the same family since the end of the 19th century and is now represented by Jean-Hubert Delon, the sole owner of the château and owner of Château Potensac in the Medoc and Château Nénin in Pomerol.

The incomparable terroir with its great diversity, for which the proximity to the Gironde is primarily responsible, gives the Grand Vin de Léoville du Marquis de Las Cases its unique, complex and sophisticated personality, which has been widely recognized for years.
