The 1989 Cos d'Estournel is very good, but uninspiring. The 1989, although good, does not live up to expectations given the terroir and the vintage. Its deep ruby color is followed by a spicy vanillin, curranty nose, medium body, excellent depth, but a monolithic personality. It possesses neither the concentration nor dimension of the exceptional 1990. The 1989 possesses some hard tannin in the finish, but it is well-integrated with the wine's ripe fruit. Look for this wine to drink well for the next 15+ years.- Robert Parker Jr. (02/1997)

Full medium ruby. High-pitched, perfumed aromas of dark berries, minerals and violet; very cabernet. Rich, dense and youthful; broad and beefy, with cassis, black cherry and bitter chocolate flavors. Finishes very sweet and long, with fine tannins spreading out impressively to coat the palate. A great showing. Drink now through 2015. ST
