pressure question

[halenrush]

So I have two taps, but will have three kegs of beer hopefully by the end of the month.  I want to bulk age one for a few months.

If I have a carbonated keg of beer at about 10psi, then take it off the regulator, will that carbonated beer stay at 10 psi or will it eventually be absorbed into the beer?  And if it does, will there be some degree of c02 on top of the beer?  And when I finally decide to dispense, I should be able to hook it up and go, right?

I make it a point to have the beer carbed to the level I want before disconnecting to store for an extended period of time. If you have it carbed like you say and then top off to 10psi it all really depends on what level of carbonation your beer is set at. Highly carbed beers wont absorb more CO2 but lightly carbed beers will. I like being able to connect, chill and serve.

I learned this after I had a beer toped off to 20 psi (just in case state of mind) and I did not label it as such. Connected it to my gas out at 6-8 psi and flooded the regulator(full keg that had the gas line just below the bev line). The regulator got a thorough cleaning, and a check valve was added.

i usually carbonate my beers to the volumes appropriate for that beer. once you’ve actually got it to that level you can disconnect it and it will stay carbonated indefinitely. [provided you have no leaks.]

i would assume you could also age beer uncarbonated [maybe with a few psi just to keep the seals on the keg tight].

I usually age my beers in the keg uncarbonated (puged w/CO2). Although I don’t know if there’s any difference aging carbonated or not.

This is the way that works for me.  8)

I will agree with you.
Once beer is fully carbonated and you do not have any leak in keg, your CO2 level will stay the same.

Once beer is fully carbonated and you do not have any leak in keg, your CO2 level will stay the same.

Assuming a constant temp.

ah, good point.

if you carbonate to 3vols @ 45f and then store it at 60f, then bring it down to 45f again before you serve, you’ll have to wait for the co2 to redissolve into solution, since the time at 60f will push it out and into the head space. you can still do this, just be sure to refrigerate it a week or so before serving. you won’t even have to hook it up to the gas, since the co2 will automagically dissolve back into solution given enough time.
