Wine Advocate-Parker : The bigger sister or brother of Le Petit Lion, depending on your point of view, the 2012 Leoville Las Cases has gorgeous minerality, plenty of blueberry and blackcurrant fruit that is super-pure, an opaque ruby/purple color, medium body and firm structured, slightly austere personality. This wine is built for the long-term. A blend of 74% Cabernet Sauvignon, 15% Merlot and 11% Cabernet Franc, it attained 13.5% alcohol, which is substantial for a 2012 Médoc. It has depth and richness, but also a boatload of tannin. Forget it for 8-10 years and drink over the following 15-20.
