I have not been kegging for very long and there are a few things I still do not understand. For instance, I learned today that when you set a regulator that is sitting in your refrigerator, the pressure can creep up a couple of psi over a few hours until it hits equalibrium. I thought I just had a faulty regulatory. Here's something I still cannot figure out:
What happens if the pressure you carbonate at is different than the pressure you use to serve? For instance, let's say I have a keg of bitter in a fridge set to 45F and set the psi at 9. The beer should get carbed to 2 units. Now say I want to serve at 15 psi. I bleed the pressure and reset to 15 psi. Won't my bitter be carbed in the next few days to an unacceptable 2.5 units? How would I avoid this without disconnecting the gas everyday?
What about the opposite? Lets say I carb at 15 psi and serve at 9 psi. Wouldn't the beer eventually go from 2.5 units to 2?
