Can Beer Affect An Ear Infection Will A Keg Filled With Beer At Near To Sea Level Be Affected If It Is Brought Up To An Elevation Of 7000?

Will a keg filled with beer at near to sea level be affected if it is brought up to an elevation of 7000? - can beer affect an ear infection

I think a barrel of beer where I live and bring a level where the altitude is 7000 meters to fill. Its just a lot cheaper. I wonder whether this pressure variation, the beer or not. Should I fill the barrel when it comes to the booth? I would be driving with the gun in a car.
