sealing keg for aging not carbonating

[Blues N Brew]

so i made a tripel on sunday and since yesterday the airlock has stopped completely not even a sign of positive pressure i dont want to bottle for at least another month, the keg( i use as fermenter) lid is not sealed and want to avoid oxygen ingress so i had to hit it with some gas 7-10 psi to seal it, question is will this add carbonation to keep some pressure in the keg to age at 68-70F for a month to 2 months? cheers

If you keep some pressure it will carbonate some. 7-10 psi for 2 months will leave you bit far to go when ready to carbonate. I’d seal and hit it. It may even keep fermenting giving you some free co2. It will age well I think. No different than waiting in kegerator or fridge space.

If you already ferment in a keg you can easily seal it off early and let the last few points help with carbonation. Spunding valve will help you control it.

That level of carbonation actually works well for what I brew but not a tripel. I know you didn’t ask about that just an aside

Yes, it will add some carbon dioxide to the beer, slightly carbonating it. If you add 7 psi at 68F, eventually you will see that pressure drop as the co2 is absorbed into the beer. If you are going to keg the beer eventually, you could hit it with a higher pressure. You will need to monitor the pressure to make sure there isn't a leak. If you are going to bottle condition the beer, you could bottle it right away and let it age in the bottle.

Either way, the co2 won't effect the aging of the beer, so the idea of pressurizing the keg is a very good and prudent idea.

Btw love the pic and your “name” on here. Welcome to the forum!

cool thanks

just took a gravity reading its still fermenting, its at 1.020 and definitely see activity in the sample and low and behold i forgot i have a blowtie valve, so i hooked it up to enough pressure to keep the keg sealed and expel any extra co2, thanks yall

As a data point, I made a lager and wanted to lager it 6 weeks in a keg at 38 F. I added CO2 at 40 psi on day zero, and on day 3 it was about 5 psi, entirely due to absorption. I repeated this twice, and the 4th time I stopped at 20 psi (it was at maybe 18) and will leave it there. I'll check in a week to re-verify no leaks but otherwise let it be.

Beat me to my suggestion. Spunding valve set to 5psi would do the trick

well after ramping temps and hooking up the blow tie, it appears fermentation decided to come back full swing clogging the blowtie with yeast, switched to blow off and for a solid 30 secs was creamy yeast just dumping into the blowoff bucket, trippy man

You bothered it, now it's pissed

yep

yep

I've seen movies. If it escapes, you and your family are finished! (Yes it's am as little drunk)

sheesh, maybe i should go grab some fire extinguishers, i assume they attack like the blob thats why( im completely sober)

If you hit it with 5 or 10 psi, then disconnect the gas, barely, if any co2 will be absorbed into the beer. If you leave the gas connected it will obviously carb up, but not if you just add a few lbs pressure then disconnect.

well its been 2 weeks down to 1006, very dry, i have a hard time thinking it will go down anymore and being a small batch dont want to take another hydro sample, show of hands in my situation would you bottle now or wait another week or 2?

 

[Minbari]

its prolly done.

 

[Blues N Brew]

its prolly done.

if you were in my shoes you'd bottle now?

Yup, even if it drops another point or two, it won't effect anything

 

[Donoroto]

Agreed. It's as done as it needs to be.
