By the way I opened the keg to siphon some beer into bottles There was already 90 gram of sugar in the keg should I put more sugar in the Keg It says in the pamphlet I got with the directors add up to 100g or more like what godsdog says to add
That should all be fine, keep the keg closed - you should have the schrader valve in the lid and digi pressure gauge from Balliihoo? Yes?
If so, make sure the keg is somewhere warmish (19-20ðC to carb up), give it a couple of days and take a pressure reading, shoud be building over a week or so to around 6 or 7 psi (makie sure you have the digi gauge set to read in psi).
If the pressure doesn't build then it suggests you have a leak and it won't be carbing up and you will need to investigate some.
I changed my kingkeg lids to Balliihoo lids and have found them to be excellent, very reliable seal and the pressure measuring valve is brill.
Good luck with it.
