Château Calon is a 100-acre estate in the highest point of Saint-Emilion. The estate is owned and operated by Jean-Noël Boidron, whose family has owned the estate since the mid-19th century. Boidron is a former lecturer in oenology at the University of Bordeaux. The wine is up to 70% Merlot, depending on vintage, blended with Cabernet Franc, Cabernet Sauvignon and Malbec. In his 1998 book on Bordeaux Robert M. Parker Jr. rated Château Calon as a “very good” producer within the Montagne Saint-Emilion appellation.
