To celebrate Independence Day weekend, we are taking a look at Bordeaux wines with American links Château Carbonnieux, that has a tree planted by Thomas Jefferson in its grounds, Château Canon, one of Jeffersons favourite wines, and three properties with American owners today; Haut-Brion, Fonplégade and Haut-Bailly. We will also have a taste of Château Giscours, an estate that was bought by two ship builders from Boston after the French Revolution.
