Pétrus is located in the Pomerol appellation, near its eastern border to Saint-Émilion. An estate of limited size, it produces a limited production red wine almost entirely from merlot grapes, on occasion with small amounts of cabernet franc, and produces no second wine. The estate belongs to the family of the Libourne wine merchant JP Moueix.
Although the wines of Pomerol have never been classified, Pétrus is widely regarded as the outstanding wine of the appellation by consensus, along with Le Pin, that in the modern era are consistently amongst the world’s most expensive wines.
In terms of production, an average year may yield at most 2,500 cases.
