lagering in kegs

[Kershner_Ale]

I want to lager a Czech Pilsner in a corny keg. Two questions: 1) do I need to install an airlock? I assume very little CO2 will be released since fermentation will be done but didn't know if that little bit mattered much. 2) if I do need an airlock, how do I modify a gas or liquid post on a ball lock corny to accept an airlock stem?

Thanks,

Jeff

If lagering at cold temps, 35F or below, and primary fermentation is done, with a stable FG, no air lock needed. I have a vienna lager in a keg now at 35F lagering.

Probably don't need an airlock, but it'd be worth purging the air out so your beer doesn't oxidize

I even put them on the gas.

+1 put them on gas. I hit my kegs up with 30 psi at 70deg when conditioning because no co2 avail in closet. It shortens amount of time needed to carb, since some of it is already done before it goes into the fridge.

Definitely purge with CO2 if you are going to lager in the keg.

A traditional Lager "purity" would have you capturing the CO2 output for carbing so even if you caught a bit of CO2 you'd be fine.
