I was wondering what you all do when cold crashing a carboy, do you leave the airlock on? The one time I did that it sucked the vodka from the airlock into the carboy. I'm not tooooo worried about that addition, but if there's no fluid in there then wont oxygen be able to pass in and out of the carboy?
On my last pale ale batch I took the airlock off and put a couple layers of Aluminum foil over the top and rubber banded it around the neck so it was tight. But is Aluminum foil permeable to air? I'm wondering now because when I bottled the batch it didn't smell hoppy at ALL, and I had dry hopped the sucker with 2 oz of hops (centennial and ahtanum) in a 2.5 gallon batch.
So any takes on the airlock and the aluminum foil, or suggestions on how I go about this next time?
