Pétrus

Pétrus occupies the highest point of the Pomerol plateau at approximately 40 meters elevation, a location that provides both natural drainage and optimal sun exposure. The estate's defining characteristic is its rare geological composition: a dense, iron-rich blue smectite clay subsoil dating back approximately 40 million years, with a dark organic topsoil layer of 60 to 80 centimetres above it. This blue clay is described as unique to the Pétrus plot: while blue clay is found throughout the Pomerol plateau, most neighboring estates have only a portion of it in their soils, whereas the entire Pétrus vineyard sits atop this geological feature. The clay retains moisture and replenishes vine roots during dry summer months, while also forcing roots to spread laterally, which is thought to contribute to Pétrus's signature smooth tannins.

• Blue smectite clay subsoil dates to approximately 40 million years old; unique concentration across the entire Pétrus vineyard compared to neighboring estates
• Dark organic topsoil is 60-80 cm thick, overlying the dense blue clay subsoil rich in reduced iron
• Plateau elevation of 40 meters provides natural drainage; clay's moisture retention compensates for summer drought conditions
• Lateral root spread encouraged by hard clay layer is believed to contribute to the wine's characteristic velvety tannin texture
• The 40-million-year-old blue smectite clay is found on only about 20 hectares across all of Pomerol, making the Pétrus plateau site among the rarest wine-growing terroirs in Bordeaux

The Pétrus vineyard covers 11.4 hectares divided into 12 separate parcels, planted entirely to Merlot since the Cabernet Franc vines were removed after the 2010 harvest. Average vine age exceeds 45 years, with planting density of approximately 6,600 to 7,000 vines per hectare; average yields are around 40 hectolitres per hectare. Vine age management has been central to the estate's identity since Madame Loubat's era: after the devastating 1956 frost killed two-thirds of the vineyard, she chose to coppice (cut back severely) the surviving vines on existing rootstocks rather than replant, a process called recépage that was previously untried in the region. This established a tradition that has maintained high average vine ages. Christian Moueix was also an early pioneer of crop thinning, practising it as early as 1973, well before the technique became widespread in Bordeaux. Harvesting is carried out by hand over two to three afternoons, deliberately avoiding morning dew to maximise ripeness and natural alcohol concentration.

• 12 parcels across 11.4 hectares; 100% Merlot since Cabernet Franc vines were removed after the 2010 harvest
• Average vine age exceeds 45 years; planting density approximately 6,600 to 7,000 vines per hectare; average yields around 40 hectolitres per hectare
• 1956 frost killed two-thirds of the vineyard; Madame Loubat's decision to coppice surviving vines rather than replant established the tradition of maintaining high vine age
• Crop thinning pioneered at Pétrus by Christian Moueix from as early as 1973, among the first estates in Bordeaux to adopt this practice
• Hand harvesting conducted over two to three afternoons to avoid morning dew; only optimal fruit reaches the cellar; severe vintage selection means no wine produced in years such as 1956, 1965, and 1991

Pétrus employs traditional Bordeaux winemaking techniques with meticulous attention at every stage. Grapes are hand-harvested and pass through an optical sorter (introduced in 2009) before fermentation in temperature-controlled concrete tanks. The wine ages for 18 to 20 months in French oak barrels, of which 50% are new; notably, new barrels are pre-soaked in water for 15 days to remove any overpowering oak flavours before use. A rigorous pre-assemblage vat selection is carried out, with certain parcels rejected from the Grand Vin to maintain quality standards. The wine is bottled without filtration. Since Olivier Berrouet took over winemaking from his father Jean-Claude in 2008, the style has evolved toward fuller, fresher expression while preserving the estate's fundamental character.

• Fermentation in temperature-controlled concrete tanks; optical sorter installed in 2009 replaced manual sorting
• Élevage 18-20 months in 50% new French oak; new barrels pre-soaked for 15 days to moderate oak influence
• Stringent pre-assemblage vat selection rejects certain parcels; wine bottled without filtration
• Olivier Berrouet has been director and winemaker since 2008, succeeding Jean-Claude Berrouet who crafted 44 consecutive vintages (1964-2007)

Records of wine production at Pétrus date to the mid-18th century, with the Arnaud family listed as owners from the end of the 18th century. The name first appears in written records in 1837, and the estate won a gold medal at the Paris Exposition Universelle of 1878, becoming the first Pomerol wine to sell at the price level of a Médoc second growth. Madame Edmond Loubat began buying shares from around 1925 and became sole owner by the mid-1940s. She partnered with Libourne négociant Jean-Pierre Moueix in 1945, granting him exclusive selling rights; according to wine historian David Peppercorn, this marked the beginning of the great age of Pétrus. The American breakthrough was significantly driven by Henri Soulé, owner of Le Pavillon restaurant in New York, who championed Pétrus on his wine list during the 1960s and helped establish its prestige in the United States. On Madame Loubat's death in 1961, the estate was divided among her niece Mme. Lily Lacoste-Loubat, her nephew M. Lignac, and a share to Moueix. Jean-Pierre Moueix purchased the Lignac shares in 1964, the same year he appointed Jean-Claude Berrouet as permanent winemaker. In 1969, Jean-François Moueix purchased the remaining Lacoste shares and separately acquired approximately 5 hectares from neighboring Château Gazin, expanding the estate from 7 to 11.4 hectares. Jean-Pierre Moueix died in 2003, and Jean-François Moueix and his children have run the estate since. In 2018, approximately 20% of the capital was sold to Colombian-American investor Alejandro Santo Domingo.

• Estate recorded from mid-18th century; Arnaud family owners until early 20th century; name first in records 1837; gold medal Paris 1878
• Madame Loubat sole owner by mid-1940s; Jean-Pierre Moueix granted exclusive selling rights in 1945; her death in 1961 transferred shares to niece, nephew, and Moueix
• Jean-Pierre Moueix bought Lignac shares in 1964 and appointed Jean-Claude Berrouet as winemaker; full Moueix family control achieved in 1969 when remaining Lacoste shares purchased
• 1969: approximately 5 hectares purchased from Château Gazin, expanding the estate from 7 to 11.4 hectares; 2018: approximately 20% stake sold to Alejandro Santo Domingo

Pétrus consistently ranks among the world's most expensive wines, alongside fellow Pomerol estate Le Pin, despite holding no official classification. Bottle prices vary substantially by vintage: approximately 1,000 euros for lesser vintages, over 2,500 euros for recognised great vintages, and up to 6,000 euros or more for exceptional years such as 1947 and 1961. The average price of a 750ml bottle has been cited at approximately $4,112. The Pétrus index tracking the ten most recent physical vintages outperformed both the Liv-ex 100 and the Bordeaux 500 over a recent five-year period. Counterfeiting is a serious concern: Pétrus is considered the most counterfeited wine in the world, and buyers are strongly advised to purchase only from verifiable, trusted sources with documented provenance.

• Bottle prices range from approximately 1,000 euros (lesser vintages) to 6,000 euros or more for exceptional years (1947, 1961); average bottle price cited at approximately $4,112
• Pétrus index outperformed the Liv-ex 100 and Bordeaux 500 over a recent five-year period, demonstrating strong long-term investment performance
• Pomerol appellation has no official classification; Pétrus's prestige rests entirely on its reputation and critical acclaim
• Widely regarded as the most counterfeited wine in the world; authentication and documented provenance are essential for purchases, particularly of pre-1975 bottles

Pétrus demonstrates extraordinary aging potential, particularly in the best vintages. The wine typically closes down shortly after release and benefits from at least 10 to 15 years of cellaring before approaching accessibility, with the greatest vintages developing gracefully for 25 to 30 years or longer. In youth, the wine shows dark fruit characteristics of plum, blackberry, and black cherry with velvety tannins and notable minerality. With age, secondary and tertiary notes emerge including leather, tobacco, truffle, coffee, spice, and earth. Bottles from the 1940s and 1950s remain remarkably drinkable, demonstrating the wine's capacity for sustained evolution. The blue clay terroir's natural moisture retention allows Merlot to achieve extraordinary ripeness and concentration while maintaining freshness.

• Young Pétrus typically closes down quickly after release; 10-15 years minimum cellaring recommended before approaching peak drinkability
• Exceptional vintages can develop and hold for 25-30 years or more; bottles from the 1940s and 1950s remain drinkable today
• Youth: dark plum, blackberry, black cherry, velvety tannins, minerality; with age: leather, tobacco, truffle, coffee, exotic spice, and earth notes
• Aromatically, Pétrus is described as potentially the most complex wine of Pomerol, combining spice, coffee, cinnamon, chocolate, dark fruit, and fresh flowers in the finest vintages
