Clos Saint Jean was founded in 1900 in Chateauneuf-du-Pape and is still a small, family-run operation known for traditionally styled wines. The estate produces 12,500 cases annually. Brothers Pascal and Vincent Maurel run the business. Clos Saint Jean produces primarily Chateauneuf-du-Pape, including one white Chateauneuf-du-Pape. The quintessential blend is 75% Grenache, 15% Syrah, 4% Mourvedre, 3% Cinsault, 2% Vaccarese and 1% Muscardin. The Sanctus Sanctorum bottling, however, is 100% Grenache from vines planted in 1905. Robert M. Parker Jr. has written that the fame of Clos Saint Jean “lies in the fact that they do not release their wines until they believe they are at the peak of perfection.”
