Lagering in kegs?

Postby mnichols » Wed Mar 08, 2006 12:58 pm

I currently have two batches of lager lagering in a beer firdge. Being the expert planner that I am...I also have another batch of lager that is ready to move to the lagering phase. Since I am running low on lagering space my question is.....Is there a problem with lagering a batch in the keg (in my keg fridge)??? I would occasionally vent the keg and after my 8 week lagering time I would transfer the batch to a clean keg.

Thanks

Nope, not a problem at all--just purge the headspace w/ CO2 or carbonate it while lagering. I do this all time, except my serving/lagering fridge is the same converted freezer set at just around 30F. I use a procedure that has the same effect as racking into another keg.

At the end of lagering, if I'm not ready to serve, I just hook up a picnic tap apply a small amount of pressure and catch the yeast that comes out until it runs clear. If I'm ready to serve, I just hook it up to the main tap and do the same thing.

Incidentally, I carbonate during the lagering phase and I don't cut my dip tubes, for this very purpose.

Hope this helps.

What pressure do you lager at???

What pressure do you set at to clear the yeast?

Thanks for the info....I may have eliminated a step thanks to you!

Most of the time I'm ready to serve the brew, so I just hook it up to my main taps. The system is balanced at 10 psi & 30F. I use about 5' of 3/16" line to get to the tap. Your first pint or two will be nothing but the yeast off the bottom of the keg--after that it's clear all the way.

If using a picnic tap, I'd set the pressure as low as possible, 1-3 psi, just enough to gently push the beer out.

BTW, another trick I learned is to put a liquid (black) quick disconnect on my gas manifold, I use this to purge the keg--gas is directed straight to the bottom of the keg while I pull on the pressure relief. Then I fill the keg. To purge the headspace, I apply a small amount of pressure and let it bubble up from the bottom. When foams comes out of the pressure relief, I know the headspace is filled. Then I seat the lid at 20 psi, and drop it back down to 10 psi for carbonating and I'm done until serving time.
