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.
