I am in the UK and was brewing the following:
Woodfordes Wherry Bitter
To see my keg in its current state click here
And to see the screw top click here
Sorry I could not paste the shots on the thread - not sure why.
The instructions said to put half a teaspoon of sugar in per pint. I may have put a little too much in. Would that have caused the bulge though?
Now I've let out a load of the CO2, I'm gonna let it condition for another 2 weeks (as per the instructions) and see what it tastes like. I don't know what green beer tastes like yet but what I drank today I am going to assume is green beer.
During the two weeks I may release a little gas here and there.
I'm sure it will all come good in the end.
Any other advice or guidance with my issue will be appreciated.
