Although there is no official classification of the Pomerol, Petrus – located in the Pomerol appellation on the right bank of the Gironde River -- is nevertheless one of the most sought-after wines in the world. Because there is no physical château on the property, the wine is often called simply Petrus. The wine’s fame began in the 1940s, when several Petrus vintages won international acclaim. Since 2010 Petrus has been made nearly entirely of Merlot, though previous vintages included tiny amounts of Cabernet Franc. Owned since 1961 by the Moueix family, the estate’s small size means that very little wine is produced, which adds to the wine’s prestige and mystique. The estate’s vineyard management has also become highly disciplined in the relatively modern practice of vendage verte, the thinning out of young grapes to encourage better ripening in those that remain. Petrus includes 28.4 acres of vineyards. The vines are 35 years old on average an annual production is 25,000 to 30,000 bottles.
Pomerol is the smallest of Bordeaux’s red wine producing regions, with only about 2,000 acres of vineyards. Located on the east side of the Dordogne River, it is one of the so-called “right bank” appellations and therefore planted primarily to Merlot. Pomerol is unique in Bordeaux in that it is the only district never to have been rated in a classification system. Some historians think Pomerol’s location on the right bank made it unattractive to Bordeaux-based wine traders, who had plenty of wine from Medoc and Graves to export to England and northern Europe. Since ranking estates was essentially a marketing ploy to help brokers sell wine, ranking an area where they did little business held no interest for them. Pomerol didn’t get much attention from the international wine community until the 1960s, when Jean-Pierre Moueix, an entrepreneurial wine merchant, started buying some of Pomerol’s best estates and exporting the wines. Today the influential Moueix family owns Pomerol’s most famous estate, Château Pétrus, along with numerous other Pomerol estates. Pomerol wines, primarily Merlot blended with small amounts of Cabernet Franc and Cabernet Sauvignon, are considered softer and less tannic than left bank Bordeaux.
