Overcarbonation question

[Jtvann]

So I am pretty sure I over carbonated in my unitank. I'm not worried about it, but wanted to run this possible solution by all.

I plan on kegging the full 10 gallons. If i set my regulator to the pressure that i want, which is lower than the current level I'm sure, will it eventually equal out?

I have 1 way back flow valves on all the lines in my system. I'm thinking that the current pressure will push back on the line, but wont escape. As beer leaves the keg, it will really be pushed out by it's own internal pressure. That pressure will eventually drop to equal the regulator pressure, at which it will all be good.

First pours will obviously be high, but that's fine.

Thoughts?

I don't think just setting your regulator to a lower pressure will do it. As the beer releases co2 in the keg from being on lower pressure, you'll have to release the excess pressure from the keg. Ive only heard of people doing this and never had to do it myself so that's about as much as I know

how many kegs of uncarbd beer are along side it? or should i say how many kegs? i have used empty kegs to push beer with residual pressure before, damn leaks!....

I'm thinking you might get excessive foaming on transfer. I guess I would try to keep pressure in primary fermentor and kegs close to same pressure, with just a little more pushing the beer out. Perhaps you could try equal pressure plus gravity. Otherwise kegs might fill with foam way before they are filled with beer.

I carb by spunding after beer is kegged, so have never had this problem, so this is just a guess.

The beer is already out of the fermenter and in the keg. It was pressure transferred so it filled without foaming.

There could be foaming as I pour into the glass. That's fine. The way I see it, no new CO2 can come in because the regulator is set to a lower pressure than is in the keg. No CO2 can come out of the keg due to the one way valves. The CO2 currently in the keg will in effect push the beer as it is poured. This loss will cause CO2 to come out of solution and into the head space. This lowering the carbonation of the beer. When it lowers enough to equal the regulator, it will be at the set point, which should then take CO2 from the tank.

Hopefully that clears it up as a lot of responses weren't addressing what I was asking.
