If I had a leak my tank would be done by now. The only thing I can think of, and it doesn't make much sense, is that I added bourbon to the keg and put it in the keezer. I didn't try to mix it or anything. Is there any chance I have a layer of high alcohol bourbon sitting on top of the beer and it's preventing it from carbing?
Well, the laws of physics state that it's impossible that it's flat.
So now what?
I dunno. But there is something that is stopping the carbonation of course. In theory, you should be able to carbonate pure liquor, but I don't know if that's true in reality. I do know that I've seen wine on tap, and it's 15% ABV so it's hard to believe that your bourbon is inhibiting carbonation.
Is there any chance that the diptube is blocked? I assume not, since you hear gas rushing in. And the regulator isn't reading incorrectly, and really at 2 psi? I'm at a loss, that's for sure.
Is the beer totally flat, like just out of the fermenter flat? Or just severely undercarbed?
