["While I am not convinced the 2005 Cos d’Estournel will eclipse the compelling 2003 Cos, it is unquestionably another superb classic from proprietor Michel Reybier and his brilliant winemaker, Jean-Guillaume Prats. Made from an unusually high percentage of Cabernet Sauvignon (78%) and the balance mostly Merlot with a tiny dollop of Cabernet Franc, this superb effort requires plenty of time in the bottle. It boasts an inky/purple color as well as a glorious perfume of licorice, Asian spices, creme de cassis, blackberries, and toasty oak. This full-bodied St.-Estephe is exceptionally powerful, pure, and dense with a layered mid-palate that builds like a skyscraper. While there are massive tannins, they are remarkably velvety and well-integrated in this big, backstrapping effort that should enjoy an unusually long life. Forget it for 8-10 years, and drink it between 2017-2040. - WA, RP (4/2008)"]

["Wonderful purity on the nose, with currants, berries and minerals. Spicy. Full-bodied, with very, very racy tannins that develop wonderfully on the palate. Expands on the palate. Cashmerelike texture. Goes on and on. Is it better than the 2003? Score range: 95-100 –JS WS WS 98 (3/2008): Black in color, with aromas of orange peel, new leather, currant, berry and Christmas pudding. Full-bodied, with layers of velvety tannins and a long, long finish of fruit and spices. The cashmere texture is all there. 2003 plus 2000 equals 2005. Best after 2015. 25,000 cases made."]
