Most wine-lovers suffer a sense of loss and enter a period of mourning, whenever a producer such as Gentaz-Dervieux ceases to exist. Even a change in name can bring out the black armbands and black veils. Perhaps the most well known are Château La Tour Haut-Brion and its white counterpart, Laville Haut-Brion. Prompted by a recent thread on Your Say, the Vinous subscriber forum, this Cellar Favorite takes a brief look at a dozen or so mature vintages of Laville Haut-Brion, mostly from the 1960s, 1970s and 1980s.
