The wine is named after Saint Peter.
Petrus 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.
