Petrus

History

Petrus spent much of the nineteenth and early twentieth centuries as a respected but unremarkable Pomerol property. The estate's transformation into a global icon owes everything to Libourne négociant Jean-Pierre Moueix, who took control of distribution in the 1940s and eventually became co-owner. Moueix understood that Pomerol, then largely unknown outside France, could rival the Médoc on quality alone, and he promoted Petrus relentlessly in export markets, particularly the United States. The Loubat family, who had owned Petrus since the early twentieth century, sold their remaining share to the Moueix family in 1964 following the death of Madame Lily Loubat. From that point the estate has remained entirely within the Moueix family's control. Christian Moueix, Jean-Pierre's son, took charge of winemaking and estate management from the 1970s onward and shaped the modern identity of the wine. The Moueix family also owns or manages numerous other Pomerol and Saint-Émilion properties through the négociant house Établissements Jean-Pierre Moueix, but Petrus sits apart from that portfolio as the crown holding.

The wine achieved mythological status in part through association with powerful collectors and heads of state during the postwar decades, and its allocation-only distribution has kept demand permanently ahead of supply. There is no second label and no second wine: Petrus produces one wine each vintage, or nothing at all if conditions do not meet the estate's standards, though declassifications are extremely rare.

Vineyards

Petrus sits on a raised plateau in the heart of Pomerol, and the defining feature of the vineyard is a thick deposit of blue clay that sits beneath a thin layer of gravel and iron-rich subsoil. This clay is exceptional at retaining water during dry periods and draining excess moisture when rainfall is heavy, giving the vines a degree of consistency that many neighboring plots cannot match. The planted area is approximately eleven and a half hectares, making it one of the larger single-vineyard estates in Pomerol while still being small by any broader Bordeaux standard.

The vineyard is planted almost entirely to Merlot. A small amount of Cabernet Franc has historically been present but its proportion has varied over the years and in some vintages it does not appear in the final blend at all. Vine age is taken seriously at Petrus, and old vines are preserved as long as they remain productive. Harvesting decisions are made with particular care: the estate has been known to use helicopters in the hours before picking to dry the canopy after rain, a measure intended to avoid dilution without resorting to sorting-table intervention alone. Farming practices have moved toward greater attention to soil health over recent decades, though the estate has not pursued organic or biodynamic certification.

Winemaking

Fermentation takes place in temperature-controlled vessels, and the wines undergo extended maceration by the standards of the appellation. The aging regime relies on new French oak barrels, with the proportion of new oak historically very high, often one hundred percent in stronger vintages. The wine typically spends somewhere between eighteen and twenty-four months in barrel before bottling. Fining is practiced selectively; filtration has been reduced or eliminated in many recent vintages.

Ôlivier Berrouet, son of the longtime cellar director Jean-Claude Berrouet, now oversees winemaking and has continued the approach established across decades without dramatic departures. The wine is consistently one of the most Merlot-expressive in Bordeaux: plush, dense, and capable of extraordinary longevity despite not having the tannic skeleton associated with Cabernet-dominant Médoc wines. Petrus is sold exclusively through allocation via the Moueix négociant network, and it does not participate in the en primeur system in the conventional sense, reaching the market on its own schedule.
