On another message board I belong to, someone asked why some beer manufacturers hand dip the top of the capped bottle in wax. This is part of one reply given by a home brewer:
Can this be correct? Since the pressure inside the bottle is higher than the pressure outside of the bottle, can oxygen from the air actually want to enter the bottle more than other gasses because “oxygen still wants to be in there”? Isn’t it possible for a properly sealed capped bottle to never allow gasses to get in or out?
