When you Secondary in a Keg...

[RLinNH]

I purged the Keg with CO2, then racked on top of that. My question is do you put some CO2 on top of the Beer? I will be aging the beer in the Keg. Once it's done, I'll carb it up and put it in the kegerator.

You can purge the little bit of head space with CO2. More than likely you will have to burp the CO2 every few days depending on what temperature you are storing it at. It will continue to ferment a little which will build pressure. And eventually start to carb the beer.

You shouldn't be racking until fermentation is nearly complete. So in this case very little CO2 will be produced anyway. The little that will be produced will not be enough to impede fermentation. In any case, most kegs will not seal completely without 4-5 pounds pressure, so you may not even need to worry about burping it as the CO2 may just seep out before building up enough pressure to seal.

I did keg a barleywine once that I thought was at final gravity since the gravity did not change after a couple months. After letting it sit for almost a year I chilled it down in the kegerator so I could carbonate it. I found it to be carbonated like a soda pop! I had proved, to myself at least, that yeast will still continue to work at least a little under pressurized conditions.

I usually rack to a keg after 3 weeks, once the keg is full, I set my regulator to 10-15 psi and I fill and purge the headspace 3 times. On one of the sessions some brewer said that filling and purging 3 times should remove all/most of the oxygen.

anyone have experience lagering beers in cornies? If I put a Munich dunkel in a cornie at 4psi and 34F for a month or so, will the yeast be able to clean up the beer? Carboys take up too much room in the chest freezer.

Yes it will work fine. You might want to put your keg pressure tester on it once in a while to make sure it is not building up a lot of pressure, but I doubt it will anyway.

So here is my stupid question. When you store/age this corney, will you keep it connected to the co2 source? If not, won't the pressure drop since the co2 will be absorbed into solution?

If all you're doing is aging the beer you don't need to keep CO2 on it. I do like Herms and purge the corny, fill it, and then hit it a couple times with CO2 and purge to make sure I don't have any O2. Then just let it sit. I do "burp" it occasionally just to make sure it isn't still fermenting...especially if it happens to warm up a little bit more than I would like.

If not, won't the pressure drop since the co2 will be absorbed into solution?

After I've carbed I have been known to keep a keg around like this (i.e., not connected to the gas supply full time). I'll hit it every now and then with 14 or so pounds of pressure just to make sure it's not leaking. Once the beer has reached equilibrium with the pressure in the headspace you shouldn't lose any more pressure.
