The researchers also conducted a study of several red wine drinks that had been in the RSS for over a year.
In that study, as reported Room, Thursday (6/5/2021), In addition to the changes in the taste of the wine, this drink seems to age faster than earth wine.
Previously, researchers sent 12 bottles of Bordeaux wine to the space station in November 2019 using a Nortrop Grumman Cygnus cargo plane.
The cargo spacecraft does not carry food for the RSS astronauts.
But bring a few things to learn how gravity or zero gravity in space can affect grapes or wine as they age.
Grapes It remained in a closed tube in the orbiting laboratory for 438 days and 19 hours before returning to Earth in January 2020 aboard the cargo spacecraft X-Dragon.
Compared to the same bottle of wine that is aging at the same time on earth, red wine is aging International Space Station, Probably too old, one to two years old, or even three years old.
Illustration of wine, wine fermented beverage.
“It’s probably one, two, or three years longer than you’d expect from an aging wine on earth,” said wine writer Jane Anson.
Anson was one of 12 panelists who took part in a taste test after the wine returned from space.
Five of the panelists (including Anson) are professional wine testers.
For the first part of the experiment, the panelists were given three glasses of wine, not knowing which glass contained the wine from space.
“At the time we were looking for aromatics and visuals, if we could see a difference.
“In one of them, I saw the difference in the color of the wine. I do not know which one, he added.
For the second part of the experiment, the panelists tasted the two wines and compared them directly. According to Anson, the taste of both wines is amazing.
“The first thing to look at is, is this wine durable? Are both of good quality? The answer is, of course, yes, ”Anson said.
“Unanimously, both wines are considered excellent wines, which means that despite being on the International Space Station for 14 months, ‘space wine’ is highly sensitized,” said Philippe Dariet, a researcher at the University of Bordeaux. France.
