Château Messile Aubert sits in Montagne-Saint-Émilion, the northern satellite of Saint-Émilion in Bordeaux's Libournais region. The estate produces Merlot-based blends anchored by Cabernet Franc and Cabernet Sauvignon, wines that reflect the clay and limestone soils characteristic of this appellation. The Cuvée Prestige Montagne-Saint-Émilion and the core Montagne-Saint-Émilion both draw on the region's traditional blend proportions, while the Domaine du Roudier expression adds Malbec to the mix. These wines have been assessed by Wine Advocate, Wine Spectator, Decanter, and Wine Enthusiast.
