Pétrus is a Bordeaux wine estate located in the Pomerol appellation near its eastern border to Saint-Émilion. A small estate of just 11.4 hectares (28 acres), it produces a red wine entirely from Merlot grapes since the end of 2010 and produces no second wine. The estate belongs to Jean-François Moueix and his children.
Although the wines of Pomerol have never been classified, Petrus is widely regarded as the outstanding wine of the appellation. Petrus leads a duo of Pomerol estates in extreme prices, along with Le Pin, that rank consistently among the world's most expensive wines. Indeed, a 750ml bottle of Petrus wine is priced at an average of $2,630.
Originally a 7-hectare (17-acre) vineyard, the estate was owned by the Arnaud family since the end of the 18th century, and the name first appears in records from 1837. In the 1868 edition of Cocks & Féret, under listing Crus bourgeois et 1ers artisans Château Petrus was ranked behind Vieux Château Certan and alongside Château Trotanoy. Some vintages of this period were labelled Petrus-Arnaud. At the Paris Exposition Universelle of 1878, Petrus won a gold medal, at a time when such an event had very significant results, establishing a selling price at the level of a Médoc second growth, the first wine of Pomerol to do so.
In 1917, the Arnaud family had to sell and La Société Civile du Château Petrus, a share-holding company was set up. Around 1925, the owner of the Hôtel Loubat in Libourne, the widow Mme. Edmond Loubat, began to buy shares in the estate and continued the acquisition progressively until 1940, when she became the sole owner of the domaine.
According to David Peppercorn, "the great age of Petrus" began with the end of World War II and the successful 1945 vintage. Jean-Pierre Moueix of the Libourne négociant house Établissements Jean-Pierre Moueix acquired exclusive selling rights of Petrus in that year and the international reputation of Petrus began to grow. Mme. Loubat, who also owned Château Latour à Pomerol, remained an active vigneronne throughout her life, known for her meticulous dedication to detail and quality, and strong determination that her wine deserved to be priced equal to the great crus.
