carbonating keg in 48 hours
« on: July 22, 2016, 07:01:20 PM »
I am sure there is a chart somewhere...

I have a little over 24 hours to get a keg reasonably carbed. It doesn't have to be perfect because this is just for a buddy to have a sample while the beer develops.

Fridge is at 38F

I was thinking somewhere around 40 PSI?

You could shake it for a few minutes at 40 then hook it up overnight at regular serving pressure. It's worked for me before. The colder the better.

Be careful shaking high pressures. If you absolutely need it carb, shake at high pressure briefly, the lower to serving pressure and shake until the regulator stops making noise.

24 hours @ 40psi/38F ( I wouldn't go over that) should have the beer mostly carbed, at least well enough to let you eval the beer. Most regulators have a PRV that will only let you pressurize so high before venting anyway. Ask me how I know.....

Ok so there isn't one psi I can leave it at for 48 hours to get it reasonably carbed up?

I thought I have seen on brulosophy that they carb at 50psi for 24 hours of something.

Cool this is basically what I was looking for.

Ok, for 48 hrs, I leave it at 30psi/40F. That gets it close, then I drop down to serving pressure. As for the 24 hour plan, 40psi won't vent the regulator but I do know that some regulators will let you go higher. 30psi x 2 days or 40psi-ish X 1 day would be safest. Or the shake method which I'm not a huge fan of.

Just looking for 48 hours so I should be good. Thanks!

Agreed that 30-35 psi for 48 hrs (providing your beer is cold enough) should get you carbed enough.

Thanks! The beer was at 34f when I transferred it to the keg.

Set at 30psi for 24 then turn down to 12psi.  I do this for all my beers and works like a charm.  I don't shake too much work for me

I agree, no shake for me either

I had done "set and forget" for my first three kegging experiences (I tried shaking the first one and it just seemed awkward), but this time tried 20 degrees psi for 2 days, then turned it down to 10 psi. The only drawback was that the keg hadn't cleared as much as it would have if I had ignored it for a week.  But it's a 2.5gal keg and it was really carbed up by the first day.

Thanks for the help all. I got it reasonably carbed up but the the hop character is extremely pungent right now from the keg hops. It was necessary to rush but no harm done.
