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.
Château de Beaucastel holds a total of 130 hectares (320 acres) of land, of which 100 hectares (250 acres) is planted with vineyards, three-quarters of which is within the Châteauneuf du Pape appellation.
The winery takes its name from the Beaucastel family which lived in Courthézon in the middle of the 16th century. Records show a Pierre de Beaucastel buying a barn and some associated land at Coudoulet in 1549, and this land is still part of Château de Beaucastel's holdings. However, at this time it was an agricultural property. In 1792, the owner was called Etienne Gontard, and the first certain mentioning of vines on the property are from his inheritance 40 years later.
In the 19th century, when the Phylloxera epidemic struck the region, the owner of the domaine was Élie Dussaud, who decided not to replant the vineyards but rather to sell the property. In 1909, it was bought by Pierre Tramier, and the vineyards were rebuilt under his ownership. After him, his son-in-law Pierre Perrin took over, and expanded Château de Beaucastel's vineyard holdings considerably. The property has stayed in the Perrin family since. After Pierre Perrin, Becaustel was managed by Jacques Perrin until 1978, and after that Jacques' sons Jean Pierre Perrin and François Perrin.
In 1990 Jean-Pierre and François Perrin in collaboration with wine importer Robert Haas founded Tablas Creek Vineyard within the California viticultural area of Paso Robles. In 2006, the Perrin family and Château de Beaucastel joined Primum Familiae Vini, an association of a limited number of high-end family-owned wineries.
