["Made from 65% Cabernet Sauvignon and 35% Merlot, this is a huge, backward wine. The 1996 possesses an opaque purple color, as well as pure aromatics consisting of cassis, grilled herbs, coffee, and toasty new oak. Massive in the mouth, and one of the most structured and concentrated young Cos d'Estournels I have ever tasted, this thick, structured, tannic wine has closed down significantly since bottling. It requires 7-8 years of cellaring, and should last for 30-35 years. It is a fabulous Cos, but patience is required. Anticipated maturity: 2006-2030. - WA, RP (4/1999)"]

["A classy and impressive young Bordeaux from an appellation that stepped up in '96. Dark-colored, with plenty of currant and spice aromas, the wine is full-bodied, with very velvety tannins and allspice, berry and currant flavors. Long, long finish. One of the wines of the vintage, it's a beauty. Best after 2005. 26,000 cases made. - JS, WS"]
