After reading about Blichmanns beer injector that purges the bottle with CO2 when bottling from a keg, I was wondering if someone bottling out of a bottling bucket could improve thier brew by using a small CO2 mini-injector, and purge the bottle of oxygen. I would guess that the yeast need oxygen to carbonate, but was also wondering if enough oxygen would still be present in the beer for the yeast to do their thing. Anyone try this before? would it actually make any improvement, or would it be a waste of time and money?
