I have just tapped my first Keg and I have some questions. I am doing natural carbonation and I do half of the recommended priming sugar as is called for. The keg sat for over 2 weeks to age. My liquid line is 7' long and the gas line is 3' long. I poured the first pint and it doesn't seem to have very much carbonation/head to it. It has CO2 in it if you look through the glass there are bubbles that keep flowing up through it. The regulator is at 15psi. I have played with the pressures every few hours to see what happens now. I am finally up to 30psi and it seems to form a really nice head to the beer. I am just not sure about this though since I read all of these forums about pressures being about 15psi or so. BTW, the beer is a Dortmunder.
