The estate's Grand Vin's vineyards are located west of Ordonnac village. Its rows of vines grow on a double thalweg of gravelly-clay. They produce a very fine wine with tight texture, great richness and wonderful freshness. On the palate, the wine is pure and powerful, the tannins dense and spicy, and the finish of great depth with glorious aromas. Because of these qualities, Château Potensac is often considered to represent the "pure Medoc style". It should be noted that Potensac was the only "Cru Bourgeois Exceptionnel" of its appellation.

Chapelle de Potensac was created and first sold by Jean-Hubert Delon with the 2002 vintage. This elegant, traditionally made second wine possesses beautiful balance founded on smoothness and freshness. Its terroir of fine gravel and clay sands can be found in various parts of Potensac's historical terroir, on the edge of the village. The Chapel, reproduced on the bottle's packaging, stands in the centre of the hamlet. It is characterized by the absence of its neo-Gothic bell tower.
