So, I brewed a nice vanilla porter about two weeks ago. After 8 days I racked from the primary to the secondary, but somehow in the process the suction died and shot a bunch of air up through the tube and back into the primary.
I started the siphon again and hoped that I didn't kill the beer by injecting a bunch of air into the primary. After one week in the secondary, it was looking as though everything was going along fine, but today a few air bubbles appeared on top of the beer in the secondary. It looks somewhat similar to the post here a week ago (Mold? Infection? post) without the white film.
Is this something to worry about or is it just the air escaping? I'll try to get a photo up tonight. Thanks!
