Production & Heritage

Château Cos d'Estournel was founded in 1811 by Louis Gaspard d'Estournel and has been owned by Michel Reybier since 2000. The 2003 blend is notably Cabernet Sauvignon-dominant at 68%, with 30% Merlot and 2% Cabernet Franc — an atypical composition for this château, which historically favors a higher proportion of Merlot. The wine was aged for 18 months in 80% new French oak barrels, contributing structure and complexity while allowing the concentration of the hot 2003 vintage to fully express itself.

Tasting Notes

Aroma: The nose opens with an inky intensity of blackberry liqueur and crème de cassis, followed by layers of incense, subtle smoke, and pain grillé. With time in the glass, pencil lead, dried Mediterranean herbs, and floral notes emerge.

Taste: The entry is broad and richly concentrated, delivering black cherry, stewed plums, and graphite through the mid-palate. Espresso, licorice, and cocoa build toward the peak, while a current of charred earth and roasted meat adds savory depth. Despite the power, the wine retains remarkable freshness and poise.

Finish: Long, layered, and persistent, with lingering notes of unsmoked cigar, new leather, and dark cocoa. The tannins are resolved and silky, leaving a lasting impression of mineral-driven concentration.

How to Drink Cos d'Estournel 2003

At over two decades of age, this wine benefits from 60 to 90 minutes of decanting to allow its complex aromatics to fully unfold; serve at 16–18°C (61–64°F) in a large-bowled Bordeaux glass. It drinks beautifully on its own as a contemplative pour. For a food-forward approach, pair it with grilled rack of lamb seasoned with rosemary — the wine's herbal undertones create a natural bridge. A braised short rib with red wine reduction mirrors the wine's depth and concentration. Aged hard cheeses such as Comté or Manchego complement the cocoa and graphite character on the finish.

How does Cos d'Estournel 2003 compare to Château Montrose 2003?

As a Deuxième Cru Classé with 98 points from Robert Parker and 96 points from Wine Spectator, the 2003 positions firmly in the ultra-premium tier and represents one of the most critically lauded vintages in the château's modern history, offering strong value relative to comparably scored First Growths.

Why Cos d'Estournel 2003?

The 98-point score from Robert Parker's Wine Advocate places this among the highest-rated vintages in the château's history, and additional scores of 96 from Wine Spectator, 95 from both Vinous and Wine Enthusiast reinforce the consensus. The atypically Cabernet Sauvignon-dominant blend at 68% gives the wine a structural backbone uncommon for Cos d'Estournel, while the extreme heat of the 2003 growing season produced a concentration and ripeness that has aged with unexpected grace. Now past its second decade, the wine has evolved from its once-flamboyant youth into a layered, savory expression that rewards patient attention — a benchmark for what Saint-Estèphe can achieve in a great vintage.
