Just a WEE bit overcarbonated

[kilroy]

I'd like to chalk this up to learning from my own mistake, but I decided that I needed to force carbonate my 1st keg to get it ready for Thanksgiving by doing the 12 hours of 30 psi with occasional rolling then reduce to serving pressure till it equalized...

WELL... I accidentally kept it at 30psi for um.... 3 days... yeah...

I've vented the pressure, but with the beer at an ungodly amount of overcarbonation, I have no idea how long I should keep the pressure off to get it back down from non 99% foam, no in liquid bubbles to normal...

Any thoughts?

if you havent already done so, cool it down to serving temp, this may help.


Other than that, bleed it off and try it several times. I would wait 15-20 min to let pressure stabilize with in the beer before you sample.

Good luck

you can set the relief valve to stay open on most kegs... mine have a ring... and if you twist it just right you can keep the valve open... try that for 12 hours and see what happens.... you can also try increasing your serving tube length (you wish) or try putting a 1 foot long 2x4 or 1x4 on each side of the tube and squeeze down with clamps.... this will not reduce the carbonation but will increase the resistance of the serving line and reduce the foam.... otherwise you are fucked.

I've never overcarbonated THAT much, but my last batch of IPA I went a little overboard on the carbonation. I just let out the pressure, gave it a little shake, released the pressure again, then let it sit overnight. The next afternoon I let out the pressure, and by night the carbonation seemed to be perfect.

It takes some finess, but it can be brought back down, I think.

Kilroy, the colder the liquid the more CO2 it can hold, SO, warm it up a bit and bleed the pressure.

i.e. take it out of the fridge for half-a-day and open the relief valve (positive pressure = no chance of cooties).

Suck it,

okay... the keg was already at serving temp when I started, and I knew something was wrong when I put in a 6' 3/16" line and got 95% foam at 10psi.

I've left the keg to decarb with the valve closed, checked it this morning, and its better, but maybe 2/5 of the way so I released the pressure again and will check it this afternoon. I'm thinking I had the beer at damned near 20%!
