Do breweries sparge beer bottles before bottling? I'm not sure I understand the puspose(s) of sparging alcohol bottles.
purging is to remove oxygen, and yes all of the good commercial breweries do that when they are bottling, purge with CO2, that is. otherwise the beer has a pretty bad shelf life.
alternately the head space can be purged by driving some CO2 out of solution right before the bottle is capped.
