Passions at the heart of Médoc. Alexandra Baudricourt is once again being put to the test. Since the inexplicable accident of her head of culture, problems have been piling up. Florence, overworked, is at risk of resigning. Her relationship with Nicolas, her husband, is falling apart. And her main distributor in supermarkets has just been placed under judicial reorganization. The estate is in the red. Alexandra seems to only be able to rely on Jean-François Tacles, an ambitious businessman, producer of wines with questionable qualities, but with whom she has fallen in love. Between twists and turns, Corbeyran and Espé introduce us to the specificities of the Sauternes appellation and the art of cooperage. A new volume of Châteaux Bordeaux, blending educational narrative, thriller, and family saga.
