Cos d’Estournel 2018: an exceptional Saint-Estèphe in a magnum
Château Cos d’Estournel is one of Bordeaux’s most recognizable estates. The château in Saint-Estèphe owes its name and distinctive character to Louis-Gaspard d’Estournel, who sought out international markets in the nineteenth century. The pagoda-like architecture and exotic details reflect that trading history and make the estate unique.
Origins and History
The vineyards are located in the southern part of Saint-Estèphe, close to the border with Pauillac. Gravelly soils and Cabernet Sauvignon contribute to the wine’s structure. Behind the striking buildings lies an estate that combines tradition with modern techniques in the cellar. The wine is prized for its concentration and aromatic depth.
The Story of the Vintage
The warm and dry part of the 2018 growing season produced ripe grapes. The 1.5-liter magnum bottle offers this concentrated vintage exceptional aging potential.
Character and Development
Black berries, plums, cocoa, and subtle spices give the wine a rich character. The tannins provide structure and allow for further bottle aging. Over time, notes of tobacco, cedar, and earthy nuances may complement the fruit notes. The balance between ripeness and freshness remains key to the wine’s overall character.
Storage and Serving
Serve this wine with lamb, roast beef, or a dish with mushrooms. After opening, let it rest in the glass for a moment and taste it before deciding whether decanting is necessary. Store the bottle in a dark, cool place at a stable temperature. An older Bordeaux may develop sediment; if so, stand the bottle upright beforehand and pour carefully.
A magnum holds 1.5 liters of wine. The ratio of wine volume to oxygen differs from that of a standard bottle, which can affect how the wine ages in the bottle. This makes this size particularly appealing for long-term storage or for opening on a special occasion.
