Château de Beaucastel is a winery located in the southern part of the Rhône valley in France, which is primarily noted for its Châteauneuf du Pape wines produced in a long-lived style. For its red Châteauneuf du Pape, Beaucastel includes all 13 grape varieties that are traditionally part of the blend, and uses a higher-than-usual proportion of Mourvèdre. The special Vielles Vignes cuvée of Beaucastel's white Châteauneuf du Pape is a varietal Roussanne wine, which is rare in Rhône and rarer in Châteauneuf du Pape.
