I remember tasting a number of Kirwans from the 19th century that had held up surprisingly well for over 100 years. While the 2005 will probably not last that long, it may be one of the finest wines this estate has made in the last fifty years. This brilliant, full-bodied, powerful, broodingly backward Margaux exhibits a dense purple hue along with notes of charcoal, licorice, blackberries, and graphite. Exceptionally concentrated, possessing high tannin, zesty acidity, and a 45-second finish, it should be purchased only by patient connoisseurs. Anticipated maturity: 2016-2035.
