Researchers in Bordeaux are carefully studying a dozen bottles of French wine that returned to Earth after a stay aboard the International Space Station. They announced their preliminary impressions Wednesday — mainly, that weightlessness didn’t ruin the wine and it seemed to energize the vines. AdA special pressurized device delicately uncorked the bottles at the Institute for Wine and Vine Research in Bordeaux. Ad“The wine of Bordeaux is a wine that gets its singularity from its history but also from its innovations," he told The AP. “For me, the difference between the space and earth wine ... it wasn’t easy to define,” said Franck Dubourdieu, a Bordeaux-based agronomist and oenologist, an expert in the study of wine and wine-making.
