The 2005 Cos d'Estournel is blended of 78% Cabernet Sauvignon, 19% Merlot and 3% Cabernet Franc. Deep garnet colored, it is still a little closed and youthfully shy. With coaxing, the nose is just beginning to offer glimpses at vivacious kirsch, red roses, violets, licorice and mocha scents over a crème de cassis, blackberry pie and chocolate-covered cherry core with wafts of chargrill, mossy bark and truffles. Full-bodied, concentrated and wonderfully complex in the mouth, the palate is just beginning to reveal the true potential of this wine, with tightly wound layers of perfumed black fruits and earthy notions bound by a rock-solid frame of firm, grainy tannins and finishing with epic persistence. This still needs 5-6 years, but I love how this beauty is shaping up!!

The 2005 Cos d’Estournel is another great success from this property, which is owned by Michel Reybier. A superstar of St.-Estèphe in this vintage, this wine has a dense ruby/purple color, beautiful, sweet cassis and blackcurrant fruit, some floral notes, spice and a touch of oak in a full-bodied, layered, impressive multi-dimensional style. The tannins are surprisingly sweet and well-integrated, as is the acidity, alcohol and wood. This is a beauty and certainly the top wine of St.-Estèphe. Drink it over the next 25+ years.
