How long will it stay in corny keg

[cbotrice]

I am going to try and put a little age on my next brew by taking it from secondary to corny flushing with co2 and letting it sit in the basement. How long can I let it sit in a northern Illinois basement with just co2 on it in a corny? TIA MP Wall

I can't say how long for sure, but a while back, I let a brew sit in a keg (refrigerated) over a year without touching it. It was a stout and I didn't really like it when I first kegged it. After a year, I needed the keg and it was either dump it or drink it. I tried it and must say that it was really good! I finished off the keg w/ no problems.
