Le Vieux Donjon is a French wine producer located in Châteauneuf-du-Pape. The modern estate was established by Marcel Michel in 1966, making it young by European standards, but around a third of the estate's vines are more than 100 years old.The estate owns 15 hectares (37 acres) of vineyard in the southern Rhône, all of it farmed organically. These are almost exclusively planted to red varieties, including Grenache, Mourvèdre, Syrah and Cinsaut. Just one hectare of the vineyard is planted to the white varieties Roussanne, Grenache Blanc and Clairette for Le Vieux Donjon Blanc.
