Wrong; you dont need liquid at all. It is pointless.

It's somewhere between 1/4 and 1/2 gallon of liquid. Probably closer to the quarter. I used a bit more than normal because this yeast pushed a lot out and the end kept getting stopped up by the yeast cake in the blowoff.

The liquid is to prevent excessive air exchange, not contamination. Even with pressure from CO2, some O2 will get in.

I do always however, make it a note to remove it and plug the stopper before cold crashing. I've not quite figured out a better way even though there is some "suck in" when I'm done cold crashing and remove the stopper.

So what? You can ferment beer in open containers. I use buckets with the lids places on loosly, or a carboy with some foil over the neck. Fermenting beer is not a process that requires special measures of isolation.

Definitely! I son't evenise an airlock when cold crashing. Why bother? Fermentation is done.

Denny - what about oxidation? Why allow finished beer to have exposure to air that isn't necessary? It's take about 60 seconds to sanitize an airlock and put it on there.

Depends on the beer. If you're going to consume it relatively fresh, sure. Aging is a different story.

Correct. And for aging, you also dont need a blowoff tube. Personally, i prefer to do my aging in a sealed keg or in primed bottles where oxygen isnt even in the picture, but if i was going to try some aging in a carboy or bucket, that's about the only use for an airlock.

The fermenter is sealed at that point. An airlock allowsgasses out, but not in. There's nothg that needs to go out at that point, so sealing the fermenter is all that's needed.
