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.
