How to rescue a flat brew?

Post by batarang » Fri Oct 03, 2008 7:50 am

Returned yesterday from a 10 day holiday. On the day I left I (King)kegged 3 brews, all primed in the usual way. Checked pressures yesterday and found one of them completely flat - guess it must be a leaky S30 valve or keg thread/O-ring problem, will sort this.
Is it now possible to rescue this brew? Could I add another priming sugar solution? or maybe a small amount of yeast along with primings? or should I just fix the leaky lid and add CO2 to the keg?
Thanks for any advise.

Don't know but, if it happened to me, I would find/fix the leak, reprime and reyeast (I' d pitch a post in Jim's to find out how much).

Depending on the level of success I'd S30 CO2 too.

Fix the leak and re-gas while chilled (the beer, that is :wink: ). This should ensure the beer soaks up the c02 then once it warms to serving temp it should be nicely carbed.

If you have CO2, the easiest route is to seal and re-gas.

If you don't, then there shouldn't be any problem repriming, stir in very gently and rouse the sediment a little. You probably wouldn't need any extra yeast, though you could add a small starter as a 'belt and braces' measure.

Either method would work IMO.

Thanks guys.
Will try a combination of all replies. First thing tomorrow will find and fix the leaky lid/valve, add and stir in gently another shot of priming sugar mixed with a little activated yeast then, float a CO2 'head' on top of the brew before screwing down the lid. Will then pressurise the barrel to check for leaks then after 3 or 4 days in the warm move it into the garage with the rest of the kegs and after about a week will crack open the tap and hopefully will get a glass of foam/beer.
How does that sound?
