Have you ever flown and ordered your favorite glass of wine only to wonder why it tastes slightly different than you have become accustomed?
Well scientists have found the answer to that. The flavor change is in the sweetness of your white or red wine. The wine itself is unaltered, but rather us who have changed. At high altitude the air is much dryer which means that our taste buds become less sensitive. This causes certain taste profiles, such as sweetness, to be dampened by altitude by as much as 33 percent.
