Pluto Gun Problem.

[paul]

The reason that the co2 gas is coming out of dilution in the beer is that the pouring pressure is too low due to the beer line being too short. Think of a stubby of beer before you take the cap off. Theres no head on it. Once you open it it releases the pressure from the stubby and a small head forms on it. This is whats happening in the keg and is visible in the beer line.



A longer beer line on the pluto will allow you to keep the beer at a higher pressure which will keep the gas disolved in the beer.

For beer to stay carbonated it needs to be stored at about 12-13 psi.

Thanks paul, I'll increase the length and see if that solves the problem, what I don't understand is why it's been perfect up until today.

cheers

Because thats when you want to really drink the stuff....

Is it possible this beer has somehow been allowed to carbonate more than previous ones? Maybe it wasn't fully attenuated before you kegged it? Was there anyone who might have screwed with the reg in your absence?

Either way it looks like Devo is on the money; the pressure you are currently using is not enough to keep the beer at its current level of carbonation, so the gas is coming out of solution. It should stabilise over time - if it does, then you know that something has changed while you were away.

It could even be due to temperature - if the fridge was recently run colder than it currently is, (and your CO2 was left connected), the beer would have absorbed more gas - now that it has warmed it is coming back out of solution.

If your system was working for you before then I wouldn't blame the line straight away - although you may have just been 'getting away with it' before.

Actually this is the only keg that i havn't force carbed, because I'm away so much i thought I'd give this one a go at carbing up over a week, not sure what the psi/kpa was now but it was whatever Ross recommended to me on another site.

All my brews spend at least 2 weeks, sometimes 3 in the fermenter.

maybe it's the Reg ?

cheers for the help

Are you serving at the same pressure you carbed at? If so, that's a balanced system and you really shouldn't have any grief.

Do you normally disconnect the gas after you force carb? If so, you may not actually be carbing to quite the same level that you've done with this one by leaving the gas on.

It's possible the reg is playing up but I reckon it's unlikely.

Have you got room to pour a bit faster? If so, try increasing the pressure a few PSI at a time and see if you can solve it that way. Otherwise maybe vent the keg and allow it to lose some fizz before trying again.

Other than that, I'm stumped.

I do disconnect after carbing, I'll increase the length of the Beer Line and up the serve pressure a bit and see how it all goes.

appreciate the advice
