The 1996 Clos du Marquis is a blend of 60% Cabernet Sauvignon (lower than recent vintages), 33% Merlot and 7% Petit Verdot (that usually goes into Leoville-Las Cases). Much like the 1996 Potensac that I tasted alongside at the château, the nose is youthful and backward with blackberry, freshly tilled soil, cedar and tobacco scents that gain intensity with aeration. The palate is medium-bodied with a smooth entry, plenty of crisp and pure black fruit laced with cedar, harmonious and long. This is a great Saint Julien at 20 years of age, firing on all cylinders and, to be honest, surpassing some of the Grand Vins in this vintage. Probably still available at a decent price, this comes thoroughly recommended. Tasted July 2016.
