force carbing a corny keg

[mancer62]

would the following be the correct step by step method to force carb my corny keg.

a. beer into keg
b. pull release ring to release oxygen and purge it out
c. blast in some co2 say 30psi?
d. you turn the co2 off when u then get to 30 psi or whatever your psi is yes?
d. disconnect from gas
e. put on floor and rock with feet or put on knee and gently rock with arms for around 15 mins
f. at this point do i purge or just put to side and forget about it? if so for how long?
g. once i reconnect to gas line do i purge then set to serving pressure ie 12psi?
h. doing this method what is the very earliest u can try drinking?

have two cornies but very unsure and very unconfident on how and when to use my co2 and try to get it working to best effect..ty

A,B,C correct leave the gas connected at your chosen Psi and rock on the floor with the gas attached so as the rocking helps the co2 to be absorbed into the beer it has to be replenished with new co2 into the corny hence leave it connected and set at you Psi. You can drink it straight away if you choose but may have to put more gas in as you draw the beer off. Ps do not overcarb by rocking it too much and having the Psi too high I would do 20 to 25 Psi myself you can always add more if its not carbed enough for you

how long would u rock keg for? so once i put 20/25psi and rock it for the designated time i can pour a drink immediately or do i then purge till psi goes down to say 10psi serving pressure?

 

[The Baron]

A couple of minutes should be enough then try it but it will depend on the style of beer i.e a bitter will be less carbed than a lager etc

If you've got enough pipe and/or flow controller you don't have to purge it. Getting the beer cold helps it carbonate. I go about 30 psi and shake the bejaysus out of it if I want to drink it straight away but normally do the 'crank and shake' as Brulosophy call it, then drop the to serving pressure on the regulator and leave it like that. The extra pressure will seep in if you've already not overcarbed. The crank and shake is like a shortcut.

Here's a force carbonation chart that's not just of the vile fahrenheit type:

if you do overcarb you can release the pressure and let it come out of solution and release again a couple of times over a day or so. and as Drunkula says cold beer will take co2 better so carb quicker

excuse my ignorance but when you put say 30psi onto your beer when it reaches this do u shut the regulator off or do u keep it on or if u kept it on would it just keep going up 35psi 40psi 50psi 55psi 60psi etc etc

 

[Drunkula]

I do 30 psi, leave on, shake for a while - if you've got the keg on its side or are doing it through the beer out post you'll hear it bubbling in and eventually stop. Then I drop the regulator to anything from 8 psi to 13 psi depending on the style and temperature the beer will be kept at and leave it at that.

I don’t think you shut the regulator but someone may say different, I just leave mine on.

 

[pms67]

You can adjust the screw and when it reaches 30 just turn it the opposite way until it stops

You do purge it first though, right? Otherwise you're shaking in one headspace-worth of air as well.

Do you have the correct regulator? If it controls flow (ie welding regulator, the second gauge will read l/min, cuft/min, etc) then the pressure would continue to rise - Do not use this type of regulator.
If the outlet gauge is psi, bar, etc then you have the correct regulator and the pressure will hold at the set pressure.

There's many ways to do this. Personally, I purge the keg with co2, then fill with beer and carbonate using the Saturation Over Time method.

My method is to crash the beer to 1 degree, then siphon into the keg. Once in the keg, purge the headspace by turning on the c02 and pulling on the PRV for a few seconds.
Then I pressurise to about 20psi and leave it overnight. Because the beer is still really cold you’ll find the co2 dissolves quickly. The following morning the keg will have warmed to its serving temperature (I have it set at 7 degrees currently for pale ales) and then I reduce the pressure to what I will serve at. After another two days it’s conditioned and ready to go.
Rocking it works but I’d rather just leave it connected for a few days

Hell yeah. I'm always commit purgery. And I put co2 into the keg before filling it.

I'm not going obsessive low oxygen but am going to fill a bag with co2 and link to to the airlock later when I do a cold crash.
