Comment on After trying them in the mountains, I think Carbonated Beverages were better closer to sea level.

Yeah but not to sea level pressure. Cruising above 10,000ft, planes are required to maintain an internal pressure equal to that of 8000ft or less, and it's usually close to that 8000ft, because that takes the least energy.
See "Need for pressurization".

The difference in apparent altitude is why your ears pop when ascending or descending.
