Already i have yet to find the answer to my problems on here. I have kegged 4 beers now and neither of them have been up to the correct carbonation. I have done the set it and forget it method, the 30 psi, and different pressures.I actually did 30 for a couple of days then 25 for 1 then to 18 for another 2-3 days. The keg is cold when carbonating. Whenever i pour the beer the first one usually has some good head but the beer is usually somewhat flat. Second one has less head and still pretty flat. I know everyone will say, line length, leak, and all the other things people say. I have checked everything and none of the "solutions" people say work. I do pour from a picnic tap so I back the pressure down to about 4 or 5 psi. Yes obviously there is carbonation because of the head, but i just dont understand why the beer is flat. Can someone give me something that finally works other than the usual answers you find if you search about the topic. I would greatly appreciate it!!
