I'm priming at the point of transferring the primary fermentation to a keg. I left the keg at room temperature for 7 days then transferred to my cellar to condition. I'm using a King Keg Top Tap which I think is leaky because after the 7 days at room temperature there was no carbonation (this is the first batch that I've primed using brewing sugar).
I'm new to all of this but I've brewed 4 batches prior to this one from Beer Kits (Woodfordes Wherry - 2 batches; Brupaks IPA - 1 batch; Youngs Bitter - 1 batch). 3 batches were primed and conditioned in the King Keg using table sugar and one batch primed and conditioned in glass bottles using table sugar. The only batch that's worked/carbonated is a Woodfordes Wherry Bitter transferred to bottles. It tastes good, even using table sugar. However, I haven't had any carbonation with the barrel which is frustrating as hell. I've tried sealing all possible leaky points with petrolium jelly.
I think I'll be returning my King Keg barrel to the manufacturer unless anyone can offer some sensible advice?!
