Among the prominent people in the town of Courthezon during the sixteenth century was the Beaucastel family. In 1549, "Noble Pierre de Beaucastel" bought "a barn with its land holdings, containing 25 saumées at Coudoulet". More than four centuries later, this remarkable domaine, known today at Château de Beaucastel, is producing what most people acknowledge to be the finest wines of Châteauneuf-du-Pape. In 1903, a young chemical engineer and mathematics professor named Pierre Perrin, together with his father-in-law, began to restore the domaine following the ravages of phylloxera. His son, Jacques Perrin, took over the domaine in 1953 and introduced many innovations such as improved grape varietals, integrated pest control, and a flash-heat exchanger. Today, the third and fourth generations of Perrins, François and Jean-Pierre and Jean-Pierre's sons Pierre, Marc and Thomas, continue in the tradition of their father and grandfather.
