It's a well known technique, described by Fruengel, among others.  alcohol
vapor is MUCH denser than air, so it will displace the air, assuming the
opening is at the top. You could also do something like purge the container
with CO2 (from a small piece of dry ice that sublimates) after adding the
alcohol.
