This estate was owned by the Dubois-Challon family since 1916, and covers 13 hectares of vines planted, predominantly, on well-drained limestone-based soils. The Château is the immediate neighbor of Ausone, situated on the south-facing slope of Saint-Emilion known as the "Côte", overlooking the distant Dordogne river. A traditional winemaking approach is adopted by Pascal Delbeck, new owner and formerly Cellar Manager of Bélair for more than 20 years, working with nature in the vineyard and adopting a minimalist intervention approach in the winery. Since 2005 the Moueix family of Libourne have taken a share in the property and now work hand in hand with Delbeck, with impressive results. Bélair shows signs of finding once more its former glory as one of the finest wines of St Emilion.
St-Émilion is a very different region to those of the Médoc, dominated by small-holding farmers and estates rather than grand Châteaux. Merlot is widely planted as is Cabernet Franc in some parts. The wines are enormously variable in style depending on the terroir, the grape variety make-up and winemaking style. Loosely the region is divided between the limestone Côtes, Graves or gravelly limestone plateau or the sandy alluvial soils nearer the Dordogne. Traditionally Médoc wines were trade from Bordeaux and St Emilions from Libourne so they have their own classification system separate to that of 1855. The classification is revised every ten years and falls into four categories, St Emilion, St Emilion Grand Cru, St Emilion Grand Cru Classé and St Emilion Premier Grand Cru Classé
Most of the district's best properties are either on the steep, clay-limestone hillsides immediately below the town or on a gravelly section of the plateau west of St Emilion itself abutting Pomerol. There are several high profile estates in the region, including Cheval Blanc, Ausone, Figeac, Le Dôme, Valandraud and Pavie.
