I usually don't use a secondary stage, but wanted to dry-hop a batch, so I left it in primary for 2 weeks (all activity had ceased) then put in secondary with some leaf hops. I use buckets, and there was several inches of head space above the beer. I guess I though there would be enough residual activity to push out the oxygen, but after two days the airlock "hat" hasn't even been pushed up. So now I'm sweating whether the beer is getting ruined because of it's exposure to the oxygen I trapped in with it?
