The entire Baudricourt family is mobilized to restore the reputation of the estate. Indeed, due to its declining quality, Chêne Courbe has long stopped communicating that it was part of the prestigious 1855 classification of Médoc wines... It is time for this to be known once again! With this goal in mind, Alexandra, who has evolved in the world of fashion design in the United States, plans to redesign the labels of their great wines. At the same time, she learns more about the treachery of Bourgeau, the former manager of Chêne Courbe, responsible for its ruin... Wine is at the heart of this grand family saga that will appeal to both connoisseurs of great wines and newcomers. A saga worthy of "Les Maîtres de l'Orge," which has already sold over 200,000 copies, orchestrated by Corbeyran and Espé.
