Saint-Estèphe third-growth Château Calon-Ségur is rumoured to have been sold for £135m.
Château Pétrus owner Jean-Francois Moueix is alleged to have been involved with the sale, though a spokesperson at Duclot, the négociant house owned by Moueix, was unable to confirm his involvement to the drinks business.
Pétrus ambassador Elizabeth Jaubert was also unable to confirm the sale, telling the drinks business: “This is the first I have heard of it.”
Calon-Ségur’s current owners were also unable to verify that an acquisition had taken place.
The purchase would include 95 hectares in Saint-Estèphe, encompassing Calon-Ségur, second label Marquis de Calon and cru bourgeois Capbern-Gasqueton.
Calon-Ségur’s future has been in the balance since the death of owner Denise Capbern-Gasqueton last September at the age of 87.
Gasqueton ran the estate, which has been owned by the Gasqueton family since 1894, after the death of her husband in 1995.
According to The Wine Spectator, several sources claim that the long-anticipated transaction is well underway and that Jean-Francois Moueix has brought in an investor.
When Château Montrose’s then-owner, Jean-Louis Charmolüe, decided to sell in 2006, Moueix brought in billionaires Martin and Olivier Bouygues.
At the time, Jean-Francois and his brother, Christian Moueix, owner of Château La Fleur-Pétrus and Château Trotanoy, acquired minority stakes in Montrose.
In July 2010 Jean-Francois bought out another minority shareholder for £1.6m.
There has not been any indication as to whether Moueix has acquired a stake in Calon-Ségur himself.
The estate has passed through several owners, including Nicolas-Alexandre, Marquis de Ségur, who aslo owned Château Laftie and Château Latour at the time.
Its signature heart-shaped label is a lasting reminder of the Marquis’ famous quote: “I make my wine at Lafite and Latour, but my heart is in Calon.”
One of the original three vineyards of Saint-Estèphe, in the early 19th century, Château Montrose was a forestland parcel belonging to Calon-Ségur.
