 The vineyard area extends 7.2 hectares with the grape varieties of 90% Merlot and 10% Cabernet Franc.The fascinating soil diversity - half gravel mixed with clay and half deep black clay - with the presence of “machefer” or iron pan in the subsoil, brings power and depth as well as complexity to the wine.Château Trotanoy’s vineyard was one of the few not to freeze in 1956, and today it is composed of very old vines, the average being close to 35 years.
