Petrus is a made almost entirely of Merlot grapes grown in Bordeaux's right bank Pomerol appellation. Although never officially classified, the chateau has long been considered on par with the First Growths from the left bank. The ownership of the estate has passed between the Arnaud family in the 19th century, to Madame Loubat at the end of WWII, and finally to Jean-Pierre Moueix in recent years. Petrus's clay soil is rich in iron and the estate's average vine age is 40 years. Chateau Petrus produces approximately 3,000 cases of wine each year. The most legendary vintages for Petrus include 1945, 1947, 1949, 1950, 1955, 1959, and 1961, in addition to recent success in 1982, 1989, 1990, 1995, 1998, 2000 and 2003. Petrus's flavor profile typically features aromas of ripe mulberry, black currant and spicy vanilla oak. The wine has incredible power, depth and richness which allow it to age for decades.
