Château Malmaison (Baronne Nadine de Rothschild) ligger i Moulis-en-Médoc og er ejet af Edmond de Rothschild Heritage. Slottet er navngivet efter Baron de Rothschild's ægtefælle, den elegante baronesse Nadine de Rothschild.
Château Malmaison is one of the oldest estates in the Médoc. Grapes have been grown here, thanks to a handful of different owners and a sizeable religious community, ever since the Middle Ages. This property, which adjoins Château Clarke, was purchased by Baron de Rothschild in 1973. Thanks to his impetus, the vineyard was restored to its former glory. He named the wine after his spouse, the elegant Baroness Nadine de Rothschild, who is also passionate by gardening. The vineyard now covers 33 ha of clay and limestone with some gravelly plots, which is ideal for Merlot, the predominant grape variety (80 % Merlot, 20 % Cabernet Sauvignon). Château Malmaison allies delicacy, suppleness and elegance with a rich and fruity bouquet – the wines combines the richness and elegance of a great Moulis. A true delight, it is characterized by its aromatic freshness and smoothness.
