Château Calon-Segur is the most northern of the classified wine estates in the Medoc. It is a Third Growth estate and is in the Saint-Estephe appellation. The name of the estate seems to come from the word “calon,” meaning a little skiff used to cross a river and for many centuries the skiffs ferried timber across the nearby Gironde estuary. In the 18th century the estate was owned by Marquis de Segur, who also owned Latour and Lafite. He supposedly said once that “I make my wine at Lafite and Latour, but my heart is in Calon.” That quote seems to have led to the heart on the label of Calon-Segur, which remains a family-owned estate. The 130 acres are planted to 65% Cabernet Sauvignon, 20% Merlot and 15% Cabernet Franc. Robert M. Parker Jr. has written that the estate “remains the most faithful to the traditional style of long-lived wines that are slow to evolve and blossom.” The estate's second wine is Le Marquis de Calon-Ségur and its third wine is Saint-Estephe de Calon-Ségur.
