That makes sense, being up in the mountains makes a lot of other things seem flat by comparison.

Agree. I don’t know if it’s reality or if my mind is making things up, but carbonated beverages have a lot more of that fizzy feeling when closer to sea level, and that is the entire reason I drink them over other beverages.

I have lived both in the mountains of Appalachia and below sea level in New Orleans.

The higher you go the less air pressure there is to keep the carbonation in the liquid. This definitely affects taste.
