The dubbel finally got done fermenting, after a good shake and another week in a warmer room. So I headed down to my local homebrew shop, and picked up a used soda keg. I was hoping to find a new one, because the price difference wasn’t that big and I’ve heard used soda kegs can have reliability problems. But they haven’t been able to get any new ones in stock recently, and only had two used kegs left, so I picked the one that looked like it was in better condition.
Getting the beer in the keg was much easier than bottles. It was easy to sterilize and siphon the beer into the keg. But that’s where the smooth sailing stopped. First, I found that I’d gotten ball-lock couplers and a pin-lock keg. So back to the homebrew shop I went and picked up the right couplers. Then I found that my store-bought 5/16″ gas line wouldn’t fit the 1/4″ pin-lock gas coupler. I had never imagined that they might use different gas line sizes (I’ve been fiddling around with kegs and plumbing long enough to know better, but for some reason I still expect things to work out by default). By the time I figured this out, the homebrew shop was closed and the Thanksgiving holiday was upon us, so the beer sat refrigerated but unpressurized over the long weekend.
Once back in town, the homebrew shop was still closed, but luckily my local hardware store helped me jury-rig an adapter. So I hooked it all up and pressurized to my normal serving pressure (8-10 psi), but the keg was leaking CO2. I tried reseating the lid and greasing the O-ring, with no success. I’ve also read that increasing the pressure will help the seal (and speed up the carbonation process), so I cranked up the pressure to 25 psi. As I increased the pressure, the sound of the CO2 leak changed in pitch, heading from a benign hiss to a worrying whine and then, just before making me truly worried, changed into a satisfying gurgle as the seal took hold and the keg started to pressurize properly.
It was then, crouched behind my kegerator, adjusting the pressure on the regular with a small screwdriver, feeling the frozen condensation on the gas line and regulator shaft, that it occurred to me that I should be worried about the whole Rube Goldberg contraption exploding. Just in time to rock the 25 psi keg around to help the carbonation get going. Standing on the other side of the kegerator made the CO2 canister less dangerous, so actually rocking a pressurized keg around on the floor didn’t seem so bad. Now that’s done, and in theory we should have drinkable beer in a few hours.
