Château Lousteauneuf sits in the Médoc, Bordeaux's Left Bank stronghold of structured Cabernet-based wines. The estate produces two core expressions: Le Petit Lousteau Médoc, a Cabernet Sauvignon and Merlot blend, and its flagship Médoc, a five-varietal composition anchored in Cabernet Sauvignon with Merlot, Petit Verdot, Cabernet Franc, and Malbec. Both wines have been assessed by Wine Enthusiast, Decanter, and Wine Spectator. The Petit Lousteau offers a more approachable entry to the house style, while the flagship Médoc layers the complexity characteristic of the region's gravelly terroirs and traditional Bordeaux blending philosophy.
