Abstract: A method and a device are described for displacing air from bottles of carbonated beverages. Sound waves may be emitted from at least one sound source and propagate through the ambient air, penetrate through the mouths into the beverage and/or make the walls of the bottles vibrate so that CO2 is expelled from the beverage and the beverage foams in the headspace such that air contained therein is displaced through the mouth. The oxygen content in the beverage can thus be reduced flexibly and in an adjustable manner with comparatively little expenditure on equipment and for different bottle formats.
