The estate has been in the same family since time immemorial and has always been handed down by women. The current owner, Jean-Hubert Delon, inherited the estate from his paternal grandmother, Georgette Liquard. Although close to the river, Potensac is situated on a high point of land in North Medoc. Because of this position, the site has been populated since ancient times. The name "Medoc" in fact comes from "medio aquae" which means "in the middle of the waters."
Planted on the best quality soils in the Ordonnac district, the vineyards now extend over 84 hectares on a terroir where the typical characteristics of each grape variety express themselves very distinctly and give the wine superb ageing potential.
