James Suckling: "This shows real precision and sophistication. Tight and dense palate that is concentrated but not heavy, with intensity and minerality. Sea salt and white pepper at the end. This is really at the top level of dry white Bordeaux now. 70% sauvignon blanc and 30% semillon."

Jeb Dunnuck: "The 2023 Château Cos D'Estournel Blanc includes slightly more Semillon and checks in as 70% Sauvignon and 30% Semillon, raised in just 7% new French oak, with the rest in once-used barrels. A selection made mostly in the cellar, it has a vivid gold hue as well as a stunning nose of ripe lemon, honeyed flowers, mint, crushed stone, and subtle hints of toast. Gorgeously textured, medium to full-bodied, and balanced, with the bright, almost racy acidity of the vintage, it's pure class."

Decanter: "Some herbal elements on the nose with peach, lime and a hint of mango, white chocolate and vanilla. Lovely weight and body, enough to be mouth filling and give some density and concentration on the palate. Lively, supple, a great richness and a touch of sweetness that gives it roundness while the Sauvignon Blanc adds crisp apple and green stone fruit. Extremely low ph of 3.14 keeps the focus on the freshness and acidity really countering the ripe fruit. A great effort this year."

The Wine Cellar Insider: "Cos d'Estournel Blanc - Bordeaux - Pomelo, lemongrass, flowers, white peach, and crisp, green apples form the bouquet. The palate is zesty, fresh, and spicy, with a flattering crispness to the fruits, paired with a touch of honeysuckle that shines in the endnotes of the finish. This is the first vintage to include the new blocks, bringing the vineyard to 10 hectares of white wine grape varietals. The wine blends 70% Sauvignon Blanc, and 30% Semillon. Drink from 2024-2032."
