A hidden air-raid shelter behind a garden hedge held decades-old wine worth £3.56 million, and 11 bottles of Romanee-Conti alone sold for £269,500 at Christie's London wine auction

England has become one of the most remarkable rare wine discoveries in recent auction history. Untouched for decades, the collection sold at Christie's London wine auction for £3.56 million, with every lot finding a buyer and several world records broken. Eleven bottles of Romanée-Conti 1971 alone fetched £269,500. If you are curious about valuable vintage wine, Burgundy, Bordeaux, champagne and port, read on to learn exactly how this hidden cellar was found, what treasures it held, and why it still matters for wine collectors.A surprise call from a couple who no longer drank led a Christie's specialist to a hidden shelterIn 2021, an out-of-the-blue telephone call from a couple who no longer really drank reached Noah May, head of Christie's Wine and Spirits department in London. It led to what he counts among his greatest discoveries. The bottles sat in a former air-raid shelter in southern England, reachable only through a thick hedge at the end of a garden. May told Christie's, in a story, about the auction house in May 2026 that the owner, who was in her eighties, worried about perishing labels and dusty conditions, and warned him not to get too excited. Her caution was understandable, since nobody could say what decades underground had done to the collection. Yet May went anyway, and what waited at the bottom of the stairs would change the expectations of everyone involved.Cases of Krug 1955 champagne, Quinta do Noval 1931 port and Mouton Rothschild 1945 lit by a phone torchAs May descended the staircase, the torchlight on his phone picked out one treasure after another. There were cases of Krug champagne from 1955, and Quinta do Noval port from 1931, along with various vintages of Domaine de la Romanée-Conti, La Tâche and Grands-Echézeaux. Then came eight bottles of Mouton Rothschild 1945, a wine May described to Christie's as arguably the greatest Bordeaux ever made. Stained labels, the very thing the owner had worried about, hinted at age rather than ruin. His reaction was immediate; May said he felt like "a poker player holding a royal flush." The moment shows why the discovery mattered so much. Champagne, port, Burgundy and claret of this calibre sat together in one forgotten room, untouched for decades.Bringing the collection to the surface and convincing its owner that stained labels were not a problemFinding the wine was only the beginning. May told Christie's that it took a long time to bring everything up to the surface, and even longer to convince the owner that the stained labels were not really an issue. In fact, he explained, the cellar had provided perfect conditions for storing wine. That was welcome news for an owner who had expected disappointment. What looked like neglect turned out to be an unexpectedly good home for wine, and the shelter had protected the bottles for decades. The collection was then offered in London in December 2021 under the title Treasures from a Rediscovered Chalk Cellar, a name that promised a story as much as a sale. Patience, in other words, was as important as expertise.Every lot sold for £3,556,396, more than double the combined low estimate, and world records fellThe result was emphatic. Christie's reports that every single lot sold, realising a total of £3,556,396, which is roughly £3.56 million and more than double the combined low estimate, while breaking several world records in the process. Leading the collection were 11 bottles of Romanée-Conti 1971, which realised £269,500 on their own. That outcome would have seemed unlikely to an owner who had warned the specialist not to get too excited. For a collection that spent decades behind a hedge, it was a remarkable return to public view. The owner's fears about perishing labels and dusty conditions proved unfounded. It also shows how much value can wait in places nobody thinks to look, and how a single telephone call can turn dusty bottles into a landmark sale.Could a forgotten luxury treasure be hidden in your home? Christie's advice to first-time sellersMay's discovery sits within a wider story. According to Christie's, its luxury category, which spans jewellery, handbags and accessories, watches, and wine and spirits, was the main entry point for new buyers in 2025 and achieved a combined total of $795 million. Rahul Kadakia, head of Global Luxury, told Christie's that its varied, relevant selection keeps drawing newer, younger buyers, particularly in luxury sales and among clients in the Asia-Pacific region. Christie's says prospective clients can request a complimentary estimate, provided the property meets the minimum consignment value, by telephone, Instagram, in person or through its online estimate service. If a forgotten cellar behind a hedge can hold more than three and a half million pounds of wine, it may be worth looking at what sits in your own attic.You use AI every day. Now get your AI Quotient.
