For the red Chateauneuf, Clos des Papes uses up to 20% of Mourvedre in the blend. Grenache and Syrah are the other main components at around 50% and 10% respectively, with the balance being a mix of all the other permitted varieties. Clos des Papes is one of the few estates to use all permitted varieties for both red and white Chateauneuf. They are well-known for producing one of the most authentic and long-lived examples of the appellation having started estate bottling in 1896. The white Chateauneuf-du-Pape also ages extremely well providing great drinking pleasure for 20 years or more.
