Tap King Homebrew success!!
I carbonated the 3.2L bottles as normal. I believe the co2 is for dispensing the beer only. I ordered some 12g co2 bulbs and a 2mm triangle screwdriver online.
I filled one bottle without replacing the co2. The first couple of glasses were ok, after that there was not enough gas to dispense the beer from the tap king. It was just dribbling out.
Next bottle, with a new co2 bulb, Success!!
very happy. Just have to let the other bottles sit for a bit longer, brew is still very new.
