(96-98) Wine Advocate - The 2020 Cos d'Estournel is composed of 62% Cabernet Sauvignon and 38% Merlot. The harvest took place September 10–24 with a yield of 39 hectoliters per hectare. The alcohol weighs in at 13.46% with a pH of 3.9 and an IPT (total phenolic index) of 80. It is being aged in French oak barrels, 55% new.
Deep purple-black in color, it pops with explosive scents of ripe red and black currants, black cherry preserves and black raspberries, followed by sparks of violets, wild sage, pencil lead and clove oil, with emerging hints of iron ore and damp soil. The medium-bodied palate has amazing elegance and grace contrasted by jaw-dropping energy, featuring a firm frame of finely grained tannins and just enough freshness, finishing with a whole firework display of mineral nuances. I love the way this Cos d'Estournel shimmies and shines—a unique vintage signature expressed so beautifully at this estate!
