1990 Cos d'Estournel - Wine Advocate #109 - Feb 1997: In contrast to the 1989, the 1990 is a spectacular wine, and, along with the 1986, 1982, and 1953, one of the four finest Cos d'Estournels made in the post-World War II era. Bruno Prats believes it is the finest wine he has ever made. In the most recent tasting, the 1990 was even better than in the past, charming me as well as other tasters with its flashy display of opulent Merlot (about 40% of the blend) mixed with ripe Cabernet Sauvignon. It was one of the more forward 1990s in the tasting, which no doubt accounted for its precocious showing. This super-concentrated wine possesses a roasted herb, sweet, jammy black fruit-scented nose, with noteworthy opulence and succulence. Pure and full-bodied, this concentrated wine conceals more tannin than it is presently revealing. The wine is open, flattering, and impossible to resist. It will continue to mature for 15-20 years.
