The Lost Vintage

Kate Elliott, an American sommelier, arrives in Meursault, Burgundy, in September 2015, despite having vowed never to return. She stays with her college friend Heather and Heather's husband Nico, Kate's French cousin, at the Charpin family winery, or domaine. Kate recently lost her job when the San Francisco restaurant where she worked closed, and her mentor, Jennifer Russell, a South African Master of Wine, has urged her to study French wine firsthand. She must pass the practical portion of the Master of Wine exam, the world's most difficult wine qualification, on her final allowed attempt. Kate also dreads encountering Jean-Luc, Nico's best friend and neighboring winemaker, with whom she had a serious relationship over a decade earlier. She broke off their engagement by phone after returning to California, consumed by doubts about living permanently in France.

Kate and Heather begin clearing the domaine's cluttered house cellar, a project Heather is eager to complete for reasons she will not explain. They discover a locked vintage suitcase bearing the initials H.M.C., containing 1940s-era women's clothing, a map of Paris, and old photographs, including a 1938 image of the Charpin family alongside an unidentified teenage girl. They also find a French secondary-school diploma dated July 1940, awarded to a previously unknown relative: Hélène Marie Charpin. Nico warns that his father, Uncle Philippe, the domaine's stern patriarch, refuses to discuss the past.

Woven through Kate's present-day story are diary entries written by Hélène, beginning on her eighteenth birthday in September 1939. Hélène is Edouard's daughter from his first marriage; her mother died when she was young, and her stepmother Virginie resents her. A gifted chemistry student, Hélène dreams of studying at the prestigious women's science university at Sèvres, near Paris, but war and France's fall to Germany in June 1940 force her to remain at the domaine. Before the Occupation, Edouard teaches Hélène a secret code using pencil dots in his favorite book, The Count of Monte Cristo, and together they build a hidden wall in the cellar to conceal the family's most valuable wine. He makes her promise to protect the domaine no matter what.

As the Occupation tightens, Hélène discovers that her father is a passeur, a Resistance member who helps people cross the Demarcation Line between German-occupied northern France and the Vichy zone. He has modified the hidden cellar to shelter refugees, while Virginie joins a pro-Vichy heritage society. Hélène reunites with her classmate Rose Reinach, who was expelled from Sèvres under the regime's anti-Jewish laws and whose family faces persecution. The two use their chemistry knowledge to synthesize fungicide at the cabotte, a small stone vineyard hut, saving the diseased vines. Rose names their partnership "the Alchemists Club." Through Rose, Hélène joins a local Resistance circuit, taking the code name Marie after Marie Curie.

In 1942, when mass roundups of Jewish families reach the region, Hélène and Edouard hide the Reinach family in the secret cellar. Virginie discovers them and threatens to inform her nephew, a Vichy policeman. Edouard is forced to guide the Reinachs south, is arrested with them, and is sent to an internment camp. Virginie blames Hélène entirely.

In the present, Kate discovers a hidden panel in the cellar armoire that opens into the concealed chamber, still filled with thousands of bottles of rare prewar wine and Resistance literature. She initially concludes her family were résistants, but Heather returns from the library with devastating news: An academic article identifies Hélène as a Gestapo informer who was publicly punished after the Liberation. Heather, who is Jewish, is deeply shaken.

Nico reveals the real reason for clearing the cellar: The family is deeply in debt and hopes the hidden wine can fund a bed-and-breakfast that Uncle Philippe has opposed. Kate agrees to inventory the collection, discovering a cellar list hidden among Hélène's school notebooks. She meets Walker, an American sommelier at Jean-Luc's domaine, whose interest in the family's rumored collection raises suspicion; after they spend a night together, he takes Kate's notebook containing the inventory. Jean-Luc's girlfriend Louise, an antique bookseller, also pursues Hélène's belongings aggressively, suggesting she knows about the wine.

Hélène's diary grows more harrowing. With Edouard gone, Virginie begins a relationship with a German lieutenant who provides forbidden luxuries, including a doctor who saves her young son Benoît's life. The village ostracizes the family. Hélène takes over Resistance courier duties and helps Rose make gunpowder for the circuit. Stéphane, the circuit's leader, joins the Maquis, rural Resistance fighters hiding from German and Vichy authorities. In spring 1944, the circuit is betrayed. Gestapo agents arrest the group at a meeting in Beaune, and Hélène is shot and captured. After interrogation, she is released into Virginie's custody. She confronts her stepmother, accusing Virginie of passing information to the Germans. Virginie does not deny it. Stéphane is executed.

Kate and Nico convene the extended family to reveal the secret cellar. Uncle Philippe initially resists but admits the truth: As children, he and Kate's mother were taunted as collabos, a derogatory term for collaborators. Their father Benoît forbade anyone from speaking of Hélène, saying she brought shame on the family. This explains Kate's mother's flight from France and Philippe's secrecy. He proposes opening a bottle of the 1945 vintage to acknowledge Hélène.

Kate returns to San Francisco but continues investigating. Heather discovers that Rose Reinach was deported to Auschwitz in September 1942, deepening Kate's horror. Jean-Luc, who has been considering selling his own domaine, visits Kate and they reconnect. He urges her to seek out her great-uncle Albert at a Cistercian monastery. Kate flies back to Burgundy and meets the elderly Albert, who has dementia but insists the collaboration accusation was wrong. He mentions a clue "in Papa's favorite book."

After a confrontation with Louise, Kate and Jean-Luc recover Edouard's copy of The Count of Monte Cristo. Kate discovers Hélène's coded message: a chemical formula ending with "Au," the periodic table symbol for gold, pointing to Les Gouttes d'Or, the domaine's prized signature white wine. Matching initials carved in the cabotte lead Kate to dig beneath the marked spot, unearthing a tin that contains Hélène's complete diary.

Reading through the night, Kate and Jean-Luc learn the full truth: Hélène was an innocent résistant. Virginie was the true informer who betrayed the circuit to protect her relationship with the German lieutenant. After the Liberation, Virginie deflected blame onto Hélène, and the chaos of the épuration sauvage, the wild purge targeting accused collaborators, prevented any fair hearing. Hélène was publicly shaved, stripped, and beaten.

Jean-Luc delivers a letter from Hélène, dated November 1944, addressed to her brothers. She reveals she is leaving France alive, not dead as the family believed. Virginie, consumed by guilt, gave Hélène her jewelry to fund the journey. During the Master of Wine practical exam, Kate identifies a Meursault Les Gouttes d'Or and has an epiphany: Stewardship of the land is a privilege and a responsibility. She tells Jean-Luc he cannot sell his domaine; they must live in Burgundy together.

Three months later, Kate and Heather visit the University of California, Davis to establish a scholarship in Hélène's name, funded by a record-setting Sotheby's auction of the wine. They learn Hélène lived out her life as Professor Marie Charpin, a respected viticulture researcher sponsored to immigrate by Rose Reinach's surviving brother, Théodore. Kate receives an email confirming she has passed the exam and prepares for her wedding to Jean-Luc, reflecting that Burgundy is her once and future home.
