First off - I think its been months since my last post here. Too much work and a new policy that they don't like beer related things on my work computer will do that. Anywho.....
I've got a keg of Amber that just never got carbed up. It was forced carbed at about 12 psi at 43 degrees for 30 days, if not longer. I've got 10' long, 3/16" ID beer lines. Out of 30 or so kegs, this has happened twice. For all I know its the same keg, not sure.
Basically it just never really seemed to absorb the CO2. I did a 10G batch, and 1 keg of it was great. The other keg of the same batch tastes less well being flat and all. It pours a little flat, and I can up the CO2 to make it seem like it has carbonation but that is a cheat and doesn't solve the problem.
I assume I have a leak I can't find? But if it is a leak, wouldn't my CO2 tank have emptied after 30 days? Its a 15lbs tank that has been in use and not re-filled for 15-16 months.
As an aside, I've had this hooked up to a second 5 lbs CO2 tank at room temp for a couple of weeks as well, same problem.
Can a keg leak, causing the CO2 not to dissolve - but in a way not to drain my CO2 tank?
Did I stumble into some sort of paradox where liquid will not absorb CO2? (For all I know that is actually possible, I'm no chemist)
For some keg viewing pleasure - an old pic of mine. It has been since upgraded to 4 taps and many more stickers. Not as classy as others, but it does the job.
