Sorry to bring up an old topic, but I didnt want to start a new one with the same title. I used these prime dose caps in my last batch and the beer was bottled almost 2 months ago and has been sitting since. I did not add priming sugar, because as I understood the vague directions, All I needed were these caps. Well, so far 4 test 12oz bottles are all flatter than a carrier deck......and ideas?
