The 2018 Cos d’Estournel showed a lot of promise when I tasted it from barrel. Now in bottle and given a 2–3-hour decant, it has a gorgeous and disarmingly pure bouquet, slightly high-toned with iodine scents infusing the lush blackberry and boysenberry scents. The oak is seamlessly integrated. The palate is fresh and crisp on the entry, delivering silky-smooth tannins, perfect acidity and a sense of harmony than is very persuasive. I cannot recall a Cos d’Estournel in recent years with such fine tannins. It gently fans out toward the finish while retaining superb precision, completing what is a beautifully crafted Cos d’Estournel with a long future ahead.
