Chateau Lafon Rochet, located in the Saint-Estephe appellation of Bordeaux, is one of the ten Quatriemes Crus (Fourth Growths) in the Bordeaux Wine Official Classification of 1855. The vineyard was purchased by Guy Tesseron in 1959 and has been controlled by the Tesseron family ever since. The Chateau rests on a 41-hectare vineyard. On average, the vines are 37 years of age, although there are some that date back as far as 1938. In recent years, Chateau Lafon Rochet has begun to implement biodynamic farming techniques, and the entire vineyard uses organic farming methods. All of the wines are aged for at least 9 months in oak barrels, and around 10,000 cases are produced annually.
