Wine Advocate-Parker :
This comes from 50- to 90-year-old vines and is a blend of 79% Cabernet Sauvignon, 11% Cabernet Franc and 10% Merlot with 13.28% alcohol, 3.72 pH and an IPT of 71. The 2017 Léoville Las Cases is deep garnet-purple in color, and wow, the nose bursts with beautiful blackcurrant cordial, blackberry pie and blueberry preserve notes followed by hints of lilacs, dark chocolate, cedar chest, sassafras and licorice with emerging wafts of oolong tea, lavender and iron ore. Medium to full-bodied, the palate is an exercise in elegance and soft-spoken nuances within a mouth-coating palate of almost electric black and blue fruits, framed by very firm, exquisitely ripe, fine-grained tannins and seamless freshness, finishing epically long and wonderfully perfumed. Damn, that's good.
