What's the best way to fix kegs that are over carbonated? They do not have a foaming issue but there's a carbonation bite to them.
Temp of tested kegs were around 38F.

Make sure there's a little headspace in the kegs. Depressurize them. Shake the hell out of them by grabbing the chimes and rocking them back and forth. Depressurize again. Wait an hour or 2 and see how they taste. Repeat as necessary.
It's a hassle and not very precise, but it works.

What is your carbonation spec for kegs? What is the carbonation reading in these kegs?

Like Kugeman said, depressurizing the kegs and shaking works but will be impossible to have any sort of consistency. Depending upon the number of kegs affected, another option is to push the beer back into the bright tank and fix the carbonation level as a single batch. Once the CO2 volumes are inline with your spec, you can then re-keg the beer. Good luck.

Good question. How does one test the carbonation level of a keg?Originally Posted by Larry Doyle

Easy! With a CO2 meter (eg. Orbisphere 3654/3658) and a suitable keg fitting.
Alternatively, kegs shoudln't be that different from the tank they were filled from unless they have been gassed-up or the filling process has meant CO2 has been entrained then subsequently dissolved.
The latter can happen if the kegs are being filled too quickly against a CO2 back-pressure.

Got the meter (Zahm 1000), but it only attaches to zwickels. Do they make a fitting for kegs? Where does one get one?

Go to the hardware store and make something that would adapt to the Zahm.

We used the same type of fitting that was used to connect in the cellar for dispense, just that the outlet had a suitable fitting for our meters.
Remember you will still need to have pressure on the gas inlet (as with dispense) to make sure you have a good clean beer flow to your meter, ie. no gas breakout in the sample.

Sure, I suppose one could just take a zwickel that connects to a tri-clamp and hook the triclamp to the keg via a regular beer line. I'm on it!

Put keg in cooler overnight to stabilize temperature and let keg contents come to equilibrium with headspace gasses. You could even shake it to speed this up. Measure pressure in keg and temperature of beer and consult zahm chart.
You can purchase keg test fitting with a thermometer and pressure gauge built in. try micromatic, perlick or gwkent.
