This is a very rich white with sliced, dried mango and apple, as well as cooked apples, candle wax and light vanilla. Full-bodied, layered and intense. Big, rich wine, yet remaining fresh and vivid. Needs time to come together. A blend of 80% sauvignon blanc and 20% semillon. but the semillon really marks the wine. Searing acidity, too. Try after 2021.

Oyster shell, lemon and green apple aromas leap from the glass, leading to a bright palate with impressive length, marked by wet stone and pear. Crafted from northern vineyard plots at the end of the Gironde estuary, the cool climate coupled with natural ventilation yield aromatic precision. Less than 1,000 cases produced annually. Try with seared scallops, roast chicken or leek and parmesan risotto seasoned with truffle.

A blend of 80% Sauvignon Blanc and 20% Semillon, the 2017 Blanc comes sailing out of the glass with bold notes of white peaches, fresh pineapple, lemon tart and lime cordial plus suggestions of honeysuckle, beeswax and musk perfume with a touch of wild sage. Medium-bodied and with a beautiful silky texture, the palate is packed with vibrant stone fruit and tropical fruit flavors, sporting a racy line of freshness, and it finishes long with an invigorating lift.

Very alluring, with peach melba, apricot, nectarine and bitter almond notes layered seamlessly on a creamy-textured palate that runs through a long, orange blossom– and white ginger–accented finish. Distinctive and suave in feel. Sauvignon Blanc and Sémillon. Drink now through 2025. — JM

The 2017 Chateau Cos D'Estournel Blanc is a great white based on a blend of 80% Sauvignon Blanc and 20% Semillon aged ten months in mostly used barrels. This medium gold-hued effort offers bright lemon and white grapefruit notes as well as a kiss of minerality and honeysuckle. It's vibrant and racy, yet beautifully textured, balanced, and unquestionably high quality.

The 2017 Cos d’Estournel Blanc has a very attractive bouquet that offers fresh lime, apricot blossom and subtle pineapple scents that I neatly integrated with the oak. The palate is well balanced with a harmonious entry and fine acidity, plenty of lime and green apple notes mixed with caramelised pear. The palate perhaps does not quite match the attractiveness on the aromatics, but will still drink well for the next 10 years. -- Neal Martin
