Château Belair's vineyard, located on the highest plateau in the area, adjoins the town of Saint Emilion to the north-east and Ausone's vineyard to the south-east. It belonged to the Dubois-Challon family, who were also co-owners of Ausone, until 1997. Purchased in 2008 by the Moueix family, it was renamed Château Belair-Monange after Christian Moueix's grandmother, Anne-Adèle Monange. Ausone and Belair were very close in terms of growing and vinification methods. The improvement in quality since 1976 has enabled this château to regain its position among Bordeaux's elite wines. Note that Château Magdelaine's vineyard has been merged with that of Château Belair-Monange.

In their youth these are austere wines, but after ageing for a few years, they develop sumptuous aromas of fruit, spices and truffles.
