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.

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.

The 2005 Cos d'Estournel is a magical wine. The aromatics alone as mesmerizing. Mocha, dried flowers, herbs and a whole range of deeply-pitched spice notes soar out of the glass. Explosive, deep and so full of character, the Cos dazzles from start to finish. Time in the glass brings out hints of rose petal, cedar and chocolate to round things out. Cos is one of the most exotic wines of 2005 and one of the vintage's undisputed successes. What a wine!

Saint-Estèphe has a reputation for tannins, and this 2005 Cos lives up to that. But it does much more, because the tannins add richness along with intensely ripe black fruits, dark plums and figs. The dense tannins are finely balanced with fresh acidity, and a long-lasting aftertaste. Impressive.

Loads and loads of roses and tobacco with red fruits on the nose. Full-bodied, with velvety tannins and juicy flavors of plum, currants, cherries, and raspberries. I am loving the texture, precision, and powerful all around. Give this a little time.
