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 60 hectares on a terroir where the typical characteristics of each grape variety express themselves very distinctly and give the wine superb ageing potential.

The vineyards spread mainly over hilly mounds with a limestone subsoil covered with clay and gravel outcrops containing a high proportion of gravel ("graves"). These limestone soils are very similar to those found in the Saint-Estèphe appellation. On this very special terroir, some plots of Cabernet Sauvignon and Cabernet Franc planted over 80 years ago still produce perfectly ripe, healthy grapes. The hamlet of Potensac was already cited in the first edition of Féret for the special characteristics and longevity of its wines.
