Robert Parker's Wine Advocate : Since 2007, the Clos du Marquis comes from an entirely different vineyard in Saint-Julien than the Leoville Las Cases, so it is not a second wine. And there was only a small amount of frost on the western edge of this vineyard in 2017. A blend of 72% Cabernet Sauvignon, 27% Merlot and 1% Cabernet Franc, the 2017 Clos du Marquis is medium to deep garnet-purple in color and struts confidently out of the glass with vibrant notes of crushed blackcurrants, warm blackberries and fresh black and red plums with touches of cigar box and bouquet garni. Medium-bodied, the palate is chock-full of zingy black fruits, framed by firm, grainy tannins and bold freshness, finishing long with a skip in its step.
