The winery is located in the municipality of Pessac in the area Pessac-Léognan
(Bordeaux). It is one of the oldest wineries in Bordeaux, since it was founded in 1300 by the then Archbishop of Bordeaux Bertrand de Goth (1264-1314). He chose the city of Avignon as his residence in 1309 as Pope Clement V, thus establishing the French exile of the Popes, which lasted until 1377. The label therefore still shows the papal insignia today. Clemens left the estate to the bishopric of Bordeaux. At the beginning of the French Revolution (1789-1799), the estate was confiscated and sold to the banker Charles Peixotto. After numerous owners 1937 was destroyed by Hagelschauer the majority of the vineyards.
Two years later it was bought by Paul Montagne and with the support of Émile Peynaud
(1912-2004) rebuilt. Today, there is a partnership between Paul's son, Leo Montagne, and Bernard Magrez, who is responsible for the operation. Advising is the well-known oenologist Michel Rolland
(* 1947). The vineyards cover 32.5 hectares of vineyards. Of these, 30 hectares are planted with the red varieties Cabernet Sauvignon (60%) and Merlot (40%), and 2.5 hectares with the white varieties Sémillon (45%), Sauvignon Blanc 45%) and Muscadelle (10%). The extremely long-lived red wine matures for 24 months in at least 70 to 100% new barriques. Only this is classified according to the Graves classification as "Cru Classé". The two second wines are called "Le Clementin du Pape-Clément" and "Le Prelat du Pape-Clément". The white wine is aged for 12 months in barriques.
