Medoc

Château Potensac is owned by Dominique Delon, the same family that controls Léoville Las Cases (a celebrated Deuxième Cru Classé in Saint-Julien), and is managed with the same rigour applied to Las Cases; it consistently stands as the finest wine in the Médoc AOC and is considered a benchmark for what the region can achieve.

The northern Médoc lies on a peninsula formed by the last ice age's deposits of Pyrenean gravel carried down the Garonne; the gravel ridges thin dramatically north of Saint-Estèphe, accounting for the step-change in wine quality between the two appellations and the significant price differential at auction.

Goulée, produced by Cos d'Estournel's team from a 36-hectare estate in Saint-Christoly-de-Médoc, represents a fascinating experiment: a Second Growth pedigree applied to Médoc AOC fruit, producing a structured, mineral wine at under $30 that consistently demonstrates how management and selection can transcend appellation boundaries.

The Médoc appellation includes the most northerly point of cultivated Bordeaux — the Pointe de Grave — where the peninsula narrows and the Gironde meets the Atlantic; vineyards here experience measurable maritime influence from the Bay of Biscay that moderates temperatures but also increases humidity, requiring careful viticultural management.
