The vineyards of Chateau Bonnet were planted during the 16th century, by the Reynier family, wealthy merchants from Libourne. In a mere 30 years, the landscape around the house was transformed, as vines replaced forest on the surrounding slopes.
Château Bonnet lies to the North of the Entre-Deux-Mers, on the clay-chalk slopes of the commune of Grézillac, overlooking the Dordogne valley some 10km south of Saint Emilion. The estate dates back to the 17th century; when André Lurton took over in 1956, it comprised 30 hectares of vineyard, which he immediately undertook to renovate and develop.

Today, half Bonnet's production is devoted to a highly popular dry white (AOC Entre-Deux-Mers), a blend of Sauvignon, Sémillon and Muscadelle grapes, carefully vinified to preserve the freshness and bouquet of these varietals.

The other half is composed of classic red varietals - Merlots, Cabernet Francs and Cabernet Sauvignons - producing noteworthy clarets widely held to be superior to the general run of the appellation.
