Hi Everyone,
I took my CO2 tank from the 2nd hand kegerator I bought in to get refilled at the LHBS. It was expired, so the guy said it'll take a week and a half before he can get it recertified for me. Not knowing if there were quicker options, I left it with him. In the meantime, I have an Amber Ale ready to be kegged.

I was thinking I could put it in a keg and prime it with sugar so it's ready when I get the tank back. The only issue is everyone says to top off the keg with CO2 when you do this. Given I don't have CO2, should I just wait?

Thanks

No, not necessarily. I mean, when people bottle, do they top off with CO2?

Don't allow a ton of headspace, and think of the keg as a giant bottle.

I do this all the time. Some people say that at least some of their corny kegs won't seal without a few PSI of CO2, but I have never had that problem. So I guess it depends on the condition of the keg and seals.

Maybe I'll hold off then. I've never used this keg before and I don't want to lose this batch of beer.
