The other day I was transferring my Milk Stout to a secondary and all of the sudden my auto-siphon started spewing bubbles that were seemingly coming from nowhere. I think the rubber ring around the piece that fits inside the larger tube was loose and it was sucking air from the top of the siphon somehow. It's still kind of a mystery, but the point is that the Milk Stout flowing through the siphon got blasted with some pretty serious air bubbles. It didn't happen the entire time but in a few random bursts so my question is what is the actual risk of oxidization? Would some air bubbles in the siphon during transfer cause oxidization? I certainly hope not but input is welcome.
