The name of this property is taken from two former owners: Malescot and Saint Exupéry, the grandfather of the famous aviator-writer. Château Malescot Saint Exupéry adjoins part of Château Margaux's vineyard. The soil in the vineyard consists of Pyrenean gravel. After a period of producing relatively disappointing wines between 1960 and 1980, the current owners focused their efforts on improving quality. From the beginning of the 1990s, the wines, with aromas of red fruit, have become richer and more intense, and have been more consistent. They are also now refined, offering a more delicate body.

Jean-Luc Zugler took over ownership in 1994 and now runs the château alongside his daughter. They are determined to raise their Troisième Grand Cru Classé from the 1855 classification to new heights. The fine wine, which accounts for around 70% of production, is produced using sustainable methods and four grape varieties typical of the appellation: Cabernet Sauvignon, Cabernet Franc, Merlot and Petit Verdot. These vines draw their nutrients from gravelly soils that absorb daytime heat and gently release it to the vine stocks at night. The nearby ocean provides a refreshing influence, helping to preserve the freshness of the berries, which are vinified with minimal intervention. Maturation lasts between 12 and 14 months in barriques, with up to 70% new oak.
Renowned for its exceptional elegance and often described as feminine, this wine boasts an impressive ageing potential of up to thirty years.
