It tastes like flowers. It smells like a campfire. What is it? It is a $6,000 bottle of Petrus Pomerol wine that spent a year on the International Space Station. Researchers in Bordeaux are examining the twelve bottles of wine as well as 320 pieces of grapevines(葡萄藤) that returned to Earth in January. They say the wine and grapevines are part of a longer-term effort to make plants on Earth better resist climate change and disease. Alcohol and glass are not usually permitted on the International Space Station. Each bottle was packed inside a special steel container during the journey.
At a special tasting this month, 12 wine experts tried one of the space-traveled wines at the Institute for Wine and Vine Research in Bordeaux. They tasted and smelled the wine together with a similar bottle from the same year that had stayed on Earth. The tasting was blind, meaning the experts did not know which wine they were drinking.
Nicolas Gaume is the head of Space Cargo Unlimited, the company that arranged the experiment. He said the experiment studied the effects of the lack of gravity on the wine and vines. “I have tears in my eyes,” Gaume said about the experiment. Jane Anson is a wine expert and writer. She said the wine that remained on Earth tasted “a little younger than the one that had been to space.”
Chemical and biological study of the wine’s aging process could help scientists find a way to age fine vintages—the grapes or wine produced during one season. That information came from Dr. Michael Lebert of Germany’s Friedrich-Alexander-University. Lebert was an advisor on the project.
