The 2000 Calon Segur is one of those wines that reminds you how great the millennial vintage could be. Now at 15 years old, it has a brilliant, vivacious red berry nose infused with ash and cigar box aromas. The detail here is a beguiling and it just "sings" Saint Estèphe. The palate is medium-bodied with dense, firm tannin that provide a rigid backbone, but it is swathed in copious tobacco-drenched black fruit and a superb line of acidity. It finishes with a twist of bitter cherry on the finish that completes what is a deeply impressive Calon-Ségur; it might just outclass the 2005.

This is an ultra-fine textured red with mint, stone and blackberry aromas and flavors. Full body, fresh and bright. Extremely long finish.

The 2000 Calon-Ségur still appears quite youthful on the rim. The well-defined nose offers brambly red fruit, red currant, crushed strawberry, rose petals and cedar, and some sous-bois just loitering in the background. The palate is medium-bodied with refined tannins. This has mellowed since I tasted it in London five years ago, and touches of tobacco and tart red cherries enliven the finish. I have always loved this millennial Calon-Ségur and now it is à point and drinking beautifully. Aged in 50% new oak and 50% one-year-old for 12 months (less than nowadays.)

This is a solid, huge wine, with rich but very dry tannins. With its dense, almost black color, and its sense of brooding power, it promises long aging. It will never be in the opulent Bordeaux camp, despite its prominent new wood flavors, but will probably outlive all but a handful top wines.
