Château Margaux's grand vin accounts for 35% of production in this vintage. It stood out as a potential wine of the vintage during en primeur and it is more than living up to its promise. The concentration is stunning, with a fruit structure that is darker, tighter and more insistent than Pavillon. It's so fresh, there is an opulence here, a dense silkiness to the tannins that is fleshed out across the palate, building to a big finish with menthol freshness. This is classically-styled Margaux with aromatic acrobatics and tannins so fine that the stitching is seamless and perfectly pulled together. Even though extremely ripe, there is freshness too - the acidity measures 3.6pH. The 100% new oak is barely perceptible even now, fresh out of the cask. One to savour over the long term. Bottled in August 2017. (JA)
