Robert Parker's Wine Advocate : The 2017 Léoville Las Cases, a blend of 79% Cabernet Sauvignon with 11% Cabernet Franc and 10% Merlot from 50- to 90-year-old vines, is deep garnet-purple in color and simply sings of crushed blackcurrants, wild blueberries and plum preserves with notions of wood smoke, cigar boxes, crushed rocks and beef drippings.
Medium-bodied with wonderful intensity and vivacity, it gives a firm, fine-grained frame and a densely packed mid-palate, finishing long and earthy. This should age incredibly!
