2020 Château Cos d’Estournel, 2ème Cru Classé, Saint-Estèphe
£900 per 6 bottle case in bond

97-98 points, Michael Schuster, The World of Fine Wine
Subtle black fruit, and a lovely, insistent gravel impression, already a nose that really tempts one to linger; rich, medium-full, beautifully, imperceptibly defined by its acidity and with superfine, velvety tannin; here is a mouthcoating, sweetly ripe Cabernet core, but a ripeness absolutely without excess, and remaining so fresh; subtle, flattering, prolonged, quietly aristocratic, the very essence of grand vin, and with terrific persistence. Great Cos, providing the sort of sensory satisfaction and appeal you get in a rich, detailed, sustained mezzoforte chord from a prime orchestra. A most complete and refined claret of first-growth quality. There is such polish in all the Cos wines—a great tribute to the team, led by Dominique Arangoits. Drink 2030–2060+

The 2020 Cos d’Estournel is a very different proposition to the Les Pagodes, more so than in other years. Much more intense on the nose of intense black fruit, it is beautifully defined, with enticing scents of blackberry, Dorset plum and topnotes of blueberry and briar. After 30 minutes in the glass, it develops more Saint-Estèphe-like traits: freshly tilled soil, cigar box and touches of warm gravel. There is an openness to these inviting aromatics. The palate is medium-bodied with fine tannins (so different from the "iron girders" of yore). There is freshness and a sense of light in this Cos d’Estournel, though the backbone remains in situ on the cedar and mint finish (a nod to neighboring Pauillac, perhaps), then a lingering marine/seaweed note on the aftertaste. This is a finely crafted, very succinct Cos d’Estournel that may well be hiding something up its sleeve for after bottling, and I suspect it will gain more spine during its barrel aging. Drink 2025-2060

The 2020 is a gorgeous wine from a very unusual year in which the Merlot is a bit more prominent in the blend than usual because of dehydration in the Cabernet. Even so, the 2020 is a wine of mid-weight finesse more than opulence. All the elements are impeccably balanced throughout. Drink 2030-2050
