im sorry to disagree with you fergthebrewer but,
"Chill the keg to drinking temp...24/36 hours..the colder the more co2 the beer will take...
When cold...hook up gas...power up the keg...let more gas in...disconnect gas from keg...shake the **** out of it...or roll it on the ground for a count of 15...20..
And then repeat this 4 times....gas...take gas off...shake....
I then put it back in the fridge for a few hours...then repeat...
You have beer with bubbles in a day or two..."
you would leave the gas connected but turned off so you can watch the gauge to see how much c02 is being absorbed, and you wouldnt repeat it more than once to avoid the PITA of over carbing. and you would have the pressure set to 300kpa, drinking in 15 minutes.
"Or hook it up to and leave it on gas for a week at a high psi ( which escapes me atm)"
if leaving for a week to gas up (safest method) set pressure to serving pressure, for me thats about 70 to 80 kpa.
also you can set the pressure up high and leave for 24 hrs and your good to go. for eg, last night i kegged some beer, set pressure to 260kpa, left for 18hrs and now its perfect! remember to turn pressure down and to release some from the keg to avoid over carbing, i will say it again, over carbing is the biggest PITA!
