Okay...you guys have to help me figure this one out. I have a keg of Vanilla Bourbon Porter that has been on the gas for 3 weeks. 11 psi @38 F. It is still flat!! The other kegs on the manifold have carbed/poured fine. I have checked all connections and valves. When I bleed the pressure on the keg I hear CO2 rushing in. It just doesn't make sense!! 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?
