Château Fleur Cardinale is a Saint-Emilion Grand Cru Classé estate situated in the Saint-Etienne-de-Lisse sector on the eastern edge of the Saint-Emilion appellation in Bordeaux, France. The 23.5-hectare property has been owned by the Decoster family since 2001, and was certified 100% organic in 2024, employing self-sustainable farming techniques throughout the estate.

The vineyard's terroir features dark red clay over limestone soils on a gentle south-facing slope reaching 75 meters at its peak. The wine is a classic Bordeaux Right Bank blend composed of approximately 75% Merlot, 17% Cabernet Franc, and 8% Cabernet Sauvignon. Vinification takes place parcel by parcel in 25 small thermoregulated stainless steel vats, followed by aging for 12 to 15 months in 90% new French oak barrels, with an additional 3% aged in clay amphora for added textural depth.

This 6-liter Imperial format is equivalent to eight standard 750ml bottles, making it an exceptional collector's piece and a stunning centerpiece for grand occasions. Large-format bottles are renowned for aging more gracefully than standard bottles, allowing the wine to develop greater complexity over time. Fleur Cardinale is best enjoyed after at least 6 to 9 years of aging, with peak maturity typically reached between 8 and 22 years after the vintage.

Across celebrated vintages, the wine displays rich aromas of crushed blackberries, black plum, Morello cherries, and dark truffle, with layers of spice, chocolate, licorice, new leather, and pencil shavings on the palate. Recent vintages have received scores of 93–95 from Robert Parker's Wine Advocate.
