I recently started brewing again after a long hiatus. I brewed up a batch and it is now in the keg. The problem is that I can’t seem to get any carbonation into the beer.
The gas tank was filled about three years ago, and still has plenty of pressure.
I cooled the beer to serving temperature before pressurizing the keg about one week ago. I have been continuously raising the pressure until it sits at about 25 psi right now, but the beer is still flat.
Any ideas on why this is happening? I was a kegging novice three years ago, but I seem to remember setting the pressure to around 10 psi and being happy with the results in a few days.
My theories are: the gas is too old (although that shouldn’t matter I wouldn’t think), or maybe I should have carbonated before cooling?
BTW- the gas tank is in the keggerator with the keg, so it is cold. But again, that didn’t seem to bother before.
Thanks for any advice.
