TASTING NOTES
The 2025 Cos d'Estournel appears to be one of the finest wines this property has produced in the last decade. Unwinding in the glass with a deep bouquet of dark berry fruit mingled with violets, pencil shavings, burning embers and anise, it's full-bodied, ample and velvety, with a broad attack, layered mid-palate and beautifully fresh, concentrated flavors. All of this terroir's inherent power is present, contained within very classical proportions at 13.3% alcohol. The 2025 is a blend of 60% Cabernet Sauvignon, 39% Merlot and 1% Petit Verdot.

William Kelley, Wine Advocate, April 2026
The 2025 Cos d'Estournel was picked between September 3 and 19 and matured in 50% new oak, the analytic alcohol at 13.25%. There is just a touch of CO2 on the nose that soon dissipates, gorgeous black plum and damson aromas, pencil lead and light iodine scents all delivered with impressive delineation. The palate is medium-bodied with fine tannins, a hint of cracked black pepper and pencil lead that infuse the layered black fruit. There is a real crescendo of flavours in this Cos d'Estournel, fanning out gloriously towards the sustained finish. This is a serious Saint-Estèphe that will age supremely well in bottle.Drinking Window

A density to this, yet it remains balanced and complex, with well-integrated tannins and a juicy finish. It seems to be a wine with lots of fruit, but then it diffuses and shows open-grained, velvety tannins. Intense yet subtle blackberries, lead pencil and hazelnuts. Some flint. Persistent and reserved at the end. Great potential. A blend of 60% cabernet sauvignon, 39% merlot and 1% petit verdot.

Incense and sandalwood aromatics, combines the density and concentration of a hot vintage with the freshness and balanced alcohols of a cooler vintage, meaning both weight and lightness of touch (this is something you will hear a lot with the 2025 vintage but rarely find in reality). A real breadth and wide spectrum of possibilities are contained here, a little austere right now but these dark berry fruits and firm tannins are waiting to bloom with ageing. 3.68pH. 50% new oak. Harvest was September 3, earliest since the Reybier era (they began September 7 on 2022, and also in 1989) through to September 19. Last year in organic conversion. 2036-2055.

The 2025 Cos d'Estournel is shaping up to be one of the wines of the vintage. Grand, dramatic and sweeping, with notable textural intensity, the 2025 hits all the right notes. Even in the very early going, the 2025 is magical. Dark red/purplish fruit, spice, new leather, tobacco, lavender and mocha build effortlessly in the glass. More than anything else, I am blown away by the wine's magnificent balance. A masterpiece. 2035-2075.
