For 14 months, a French wine aged in space. Now, it has returned to Earth to be sold. A single bottle from a case of space-aged Bordeaux is being put up for sale by the auction house Christie’s. It may cost up to $1 million. The wine is a 2000 vintage Petrus. It is considered a world-class red wine made from Merlot grapes in the Pomerol region of Bordeaux. The sale was announced Tuesday in London. Tim Triptree works for Christie’s wine and spirits division. He said the bottle adds to a “greater understanding of the maturation of wine.” The money from the sale will go to the European rocket company, Space Cargo Unlimited. The company has experimented with viticulture and microgravity. It launched the 12 bottles of Petrus 2000 in November 2019, and flew them to the International Space Station. The bottles were taken back to Earth in January. They spent almost 440 days, and about 300 million kilometers, in orbit. The wine returned to Bordeaux, where a bottle was opened for a taste test at the Institute for Wine and Vine Research. Top wine experts compared the space-aged wine with Petrus bottles that stayed on Earth. Jane Anson is a leading wine critic and a writer for the wine magazine Decanter. She and the other two experts thought there was a clear difference between the two. The space bottle “seems more evolved than I would expect from a 21-year-old bottle of Petrus 2000," Anson said in Decanter. It is beautiful and nuanced, with fine tannins and a sense energy.
