Look I'm as much of a wine guy as anyone -- but (assuming they were stored at the same temperature) there is absolutely no way that spending a year in zero gravity makes any meaningful difference to the smell or taste of a winehttps://www.euronews.com/2021/03/24/chateau-petrus-does-a-case-of-top-notch-bordeaux-really-taste-different-after-being-in-spa?utm_medium=Social&utm_source=Twitter#Echobox=1616592594 …

The "explanation" is lack of convection in space which slows aging. If we assume it stopped the aging process completely (unlikely) then you are comparing the same wine from the same vintage at 20 vs. 21 years of aging. No one can tell the difference.

They asked two experts, one couldn't tell the difference and the other thought the wine that had stayed on earth tasted younger, the opposite of what you should expect given the explanation in the article!

Isn't that common with a lot of things related to wine though?

There’s stuff which clearly does make a genuine difference — grape variety, producer (and production method), vineyard, vintage. Experts in blind tastings can reliably tell these apart.

Then there’s stuff which clearly makes no difference to the taste even though people say it does — like the shape of the wine glass.

There are interesting cases like price and how the label looks, which obviously don’t affect the taste but do affect people’s perceptions of the taste — the point of blind tasting is to remove some of these biases.

Age is interesting since it obviously makes a difference, but you can’t do a side by side tasting which holds vintage constant and varies age. Experts can tell the difference between old and young wine but maybe within a threshold of 5-10 years (less for a young wine)
