My brew is now in a drinkable state, : and very nice it is to. It's a bit cloudy, which I've put down to poor temp control during fermentation, I'll know better next time. But I have a problemette. I've got a top tap King Keg with about 36 pints in it, and a pin valve. I suspected there might have been a leak, but I can't find one, however, I only seem to be able to get about 2 pints poured before I need to re-gas. That's not right is it?
