James Suckling
An incredible wine with electrifying acidity and great depth and concentration. It’s full-bodied and full of character, showing fresh and dried citrus, then honeysuckle and other white flowers. The palate takes off with bright, intense acidity. A pH of just over 3 gives a unique combination of tangy acidity and ripe fruit. Special white. 56% sauvignon blanc and 44% semillon. Best ever?

Citrus, lemon zest, mint, and crushed stone notes all emerge from the 2025 Château Cos D'Estournel Blanc, a vibrant, focused white based on 56% Sauvignon Blanc and 44% Sémillon that's being raised in 6% new barriques. On the palate, it's medium-bodied, with bright acidity and outstanding length. It's more inward and chiseled than the Pagodes release and will benefit from a few years of bottle age. This is a brilliant white.

The 2025 Cos d'Estournel Blanc was picked between August 25 and September 3 and matured in just 6% new oak. It is very fragrant and pure on the nose, Anjou pear and wild peach, vanilla pod and light chamomile scents evolving with time in the glass. Fine delineation. The palate is very well balanced, with a silver thread of acidity. Fine tension, quite persistent in the mouth, with a brisk and focused finish, this is a delicious white Cos d'Estournel that, again, will be difficult to resist once in bottle. –Neal Martin

Robert Parker's Wine Advocate
The 2025 Blanc, a blend of 56% Sauvignon Blanc and 44% Sémillon, reveals aromas of white fruits, herbs and spice. Medium- to full-bodied, it’s dense and structured with a tensile, more energetic profile than usual, concluding with a citrus-inflected, long and fresh finish.

Sometimes light and crisp, other times rich and creamy, Bordeaux White Blends typically consist of Sauvignon Blanc and Semillon. Often, a small amount of Muscadelle or Sauvignon Gris is included for added intrigue. Popularized in Bordeaux, the blend is often mimicked throughout the New World. Somm Secret—Sauternes and Barsac are usually reserved for dessert, but they can be served before, during or after a meal. Try these sweet wines as an aperitif with jamón ibérico, oysters with a spicy mignonette or during dinner alongside hearty Alsatian sausage.
Deeply colored, concentrated, and distinctive, St. Estephe is the go-to for great, age-worthy and reliable Bordeaux reds. Separated from Pauillac merely by a stream, St. Estephe is the farthest northwest of the highest classed villages of the Haut Medoc and is therefore subject to the most intense maritime influence of the Atlantic.
St. Estephe soils are rich in gravel like all of the best sites of the Haut Medoc but here the formation of gravel over clay creates a cooler atmosphere for its vines compared to those in the villages farther downstream. This results in delayed ripening and wines with higher acidity compared to the other villages.
While they can seem a bit austere when young, St. Estephe reds prove to live very long in the cellar. Traitionally dominated by Cabernet Sauvignon, many producers now add a significant proportion of Merlot to the blend, which will soften any sharp edges of the more tannic, Cabernet.
The St. Estephe village contains two second growths, Chateau Montrose and Cos d’Estournel.
