Château Cos d'Estournel 1970

Château Cos d’Estournel 1970 — Saint-Estèphe

This Château Cos d’Estournel 1970 embodies one of the most historic, time-polished and profoundly Médoc expressions of Saint-Estèphe. A Second Growth with an immediately recognisable style, Cos d’Estournel combines the power of northern Médoc gravel, the structure of Cabernet Sauvignon and a spicy, oriental and complex aromatic signature: melted cassis, dried blackberry, black plum, cedar, graphite, blond tobacco, fine leather, cocoa, liquorice, oriental spices, forest floor, light truffle, noble earth and a long mineral finish.

Château Cos d’Estournel is one of the great historic names of the Médoc, renowned for wines that are deep, structured, aromatically complex and capable of lasting for several decades. The 1970 vintage belongs to Bordeaux’s great classical years, marked by solid structure, fine concentration and remarkable ageing potential. Today, this bottle should be approached as a wine of memory and great maturity, whose expression depends strongly on provenance and storage conditions.

Terroir: Saint-Estèphe, deep gravel and controlled power

The vineyard of Cos d’Estournel is located in Saint-Estèphe, in the northern Médoc, on deep gravel rises resting on clay subsoils. This combination gives wines that are powerful, structured and capable of preserving remarkable freshness. The gravel favours drainage and Cabernet Sauvignon ripeness, while the clay brings density, depth and texture.

The style of Cos d’Estournel combines the classical firmness of Saint-Estèphe with a more exotic and spicy aromatic dimension. Cabernet Sauvignon brings cassis, graphite, cedar, tension and structure; Merlot contributes roundness, flesh and fruit depth. In the 1970, the terroir is now expressed through melted substance, still-precious freshness and very noble tertiary complexity.

Tasting notes

Appearance: garnet evolving towards mahogany, brick and brown reflections depending on storage, with more delicate visual density than in its youth. The colour reflects the long evolution of a great old Bordeaux, while a perfectly stored bottle may still retain fine luminosity.

Nose: complex, evolved and profoundly tertiary, with melted cassis, dried blackberry, black plum, preserved black fruits, cedar, graphite, blond tobacco, fine leather, cocoa and liquorice. With very cautious aeration, nuances of forest floor, light truffle, fallen leaves, oriental spices, incense, noble earth, mocha, dried mint and precious woods may appear.

Palate: broad yet delicate, velvety, melted and still carried by precious Médoc freshness. Flavours of evolved cassis, plum, cedar, graphite, tobacco, fine leather, cocoa, liquorice, forest floor and spice unfold with elegance, supported by softened tannins and a persistent mineral frame. The finish is long, fine, spicy and lightly saline, with an impression of noble maturity, calm depth and great Bordeaux classicism.

Expression of the 1970 vintage

The 1970 vintage in Bordeaux is often associated with solid, structured and long-lived wines, with serious concentration and slow evolution. In the great growths of the Médoc, it produced wines capable of developing profound tertiary complexity: cedar, tobacco, leather, truffle, forest floor, graphite, spice and noble earth. In Saint-Estèphe, this structure has allowed the best bottles to cross time with dignity.

Today, this Château Cos d’Estournel 1970 should be treated as a great old wine, highly dependent on its state of preservation. Extended decanting should be avoided; it is better to open it carefully and serve it after gentle aeration, in order to preserve its fragile balance and tertiary aromas. A fine bottle may reveal a remarkable register of cedar, tobacco, fine leather, truffle, forest floor, graphite, oriental spices and mineral nuances around melted black fruit.
