Correct.......pretty much all the basic proceedures remain the same eg: fill keg with your beer, purge air from keg ( at 60kpa ), let chill for the usual 24 hours, then turn on gas at regulator ( which is already "set" at 60 kpa ), then leave it for a week or so.....perfect.
You probably could leave the gas turned on while the keg is chilling because the beer will start absorbing the gas as it starts to chill anyway.
From about day 6 onwards, you could connect to your tap to check if it is gassed enough to your liking yet. Once it is to your liking, just shut off the regulator and enjoy. You will of course need to from time to time turn the gas back on ( during sessions ) to ensure correct pouring pressure.
Obviously make sure you have no leaks from your gas lines before leaving gas turned on for this long period of time - I have not had a leak though!
When I said I used to use the "Ross Method"............I did not actually get the instructions from Ross......but had been given similar instructions from other brew shops ( must be the "norm" ) - I just wanted to clarify that just in-case it looked to others like I may have been producing negativity towards Ross.
Are you having over-carb problems?
