Bottle inerting

The bottle inerting technology consists of flushing out the air from the headspace of a bottle/can/keg by injecting gas before seaming or capping.

Two solutions can be used: a laminar flow of gaseous nitrogen for purging the head-space by dilution; or liquid nitrogen droplets which are introduced in the bottling or canning process to help drive out atmospheric air and reduce oxygen in the liquid.
