So I've decided to properly balance my beer lines.
For ages I had the pressure at around 16psi (seems a little high now) with 3.3m of beer line, 5mm ID, with the centre of the keg sitting about 35-40cm below the tap. Line runs up into a coil on the inner side of the fridge then traveling around the inside of the fridge to the tap on the door, dropping down about 5cm to the tap.
Occasionaly it would pour the perfect beer, but was always, always under-carbonated, never looked anything like what you'd get at a pub, and a long way off bottled, sugar primed, beers form the same batch.
Re-did my calculations to 12psi with 4mm ID lines, came out to 3m's of length required aiming for a 2.57 volume of CO2.
So I just re-did the lines with 4m (so I could cut it down and account for any aberrations), same height and run of the line, dropped the pressure to 12psi and get nothing but foam. Same fittings, all cleaned, keg is fine, opened it up and re-gased it to 12psi.
Is it because I've started at 4m of length that I get nothing but foam, or is there something wrong somewhere else?
I've tried to rule out over-carbonation. Prior to re-doing the lines it would have been no higher than 18psi. I've released and dropped back to 12, I assume there's probably still 18psi dissolved but I'll check back later after leaving the gas off.
It's all clean, new line, never been used. I'm stumped and a little bit annoyed.
