great well... when i was pouring my bottles a few air bubbles popped up out of the pourer... not unless im misunderstanding oxidization. I hope i didnt screw it up...
I don't think a few bubbles is going to hurt your beer. I've had alot of oxygen exposure when I had a malfunctioning autosiphon and it didn't seem to hurt my beer. Of course thats not saying that I could be that lucky from one instance to the other.
