Would using old hard liquor bottles work? I have a couple 1L and 750 bottles of captain Morgan, Absolute and other stuff. I was just wondering if the caps on those are air tight? I don't know if oxygen is a problem for hard liquor, I imagine it is but just wondering if those could be usable.
Safe rule of thumb is: If it didn't have carbonated liquid in it then don't use it.
The bottles may not be safe for carbonated pressures.
