Overgassed Beer?

[chris_718]

Hi,

I set up a home bar about a year back, and it's been working really well (so far). I've been using the forced carbonation technique off this site for the kegs.

However, recently (the last 3 kegs I've done). The beer has become progressively too gassy... it's now at the point where I have pretty much a glass of head when I try to pour a beer... I've tried everything.. decreasing pressure, increasing pressure, decreasing the carbonation time (the "forced carbonation" time).... I dunno what else to try!!!

the last keg was gassy, but you could still pour an average beer (with about 1/4 head) by pouring the initial bit into a bucket. But now, it's pretty much all head.

Any sugegstions???

thankss

Toward the end of my kegs, about the last 5l or so, my beers get too carbonated as well. I just disconnect the CO2. I guess I should mention that I leave my gas on 24/7. The beer loses carbonation pretty quickly this way, particularly if you're drinking it quite fast. If this is too slow for you, disconnect the gas and vent the keg several times over the course of a day or so and the carbonation should fall to a more acceptable level.

Thanks,

but these kegs are full, and it's only just started... I havent had any probe before, now all of a sudden they appear to be too gassy.... could there be anything apart from overgassing that could cause this?

Two things. Either your regulator pressure has creeped up or your serving fridge temperature has gone down. Or both. Since CO2 solubility in beer is strongly temperature dependent, a rather small change in temperature can mean a rather large change in dissolved CO2. Either turn down your regulator pressure (& vent the kegs like I mentioned before) or turn up the temperature of your fridge. Or both.

I agree with everything newguy has mentioned but want to add a 3rd point from personal experience
3) Your tap/beer gun might need a good clean. If by chance it has a build up of gunk this can result in a bad pour from the normally perfect faucet with machined accuracy to a turbulent mess as it comes out. I puled my tap apart and soaked it and that fixed my problem. But again Newguy makes the two most obvious gas abosrbtion points.

In my fledgeling experience the best way to remove excess carbonation from a keg is by doing the reverse of force carbing it. Disconnect the gas then purge the keg, then shake it for around 10 seconds and purge it again. Give it another pour. If it's still too gassy then repeat the process. Every time you shake the keg without the co2 attached gas will come out of the solution and can be purged off. It works for me anyway.
