Château Sociando-Mallet is a wine estate located in the northern Médoc (the wines are bottled under Haut-Médoc appellation), and generally regarded as the equal of many classed growths. Although not featured in the 1855 Bordeaux classification, the property was rated a fifth growth in wine trading site Liv-Ex's unofficial 2011 version. It has the reputation of making full-bodied, classically structured wines with firm tannins and great aging potential from Cabernet Sauvignon, Merlot and Cabernet Franc.
