Iââ¬â¢ve brewed a beer which has now been sitting in my pressurised keg for about 6 weeks. I was quite excited about this one, but when I went to poor a pint, the beer wasnââ¬â¢t flowing out of the keg! Itââ¬â¢s more or less full, I followed the instructions including adding priming sugar so Iââ¬â¢m unsure what the problem might be? I can get maybe half a pint before it stops flowing completely. Any thoughts?
