...I figured the surface area would have an effect, just wondering if anyone had tried it?
Yup I often leave my regulator as is (around 50 - 80kPa - metric here in Oz
). Either give the keg a good shake whilst upsidedown (so you can hear the gas bubbling into the beer), or use the slipper method. Leaving reg at serving pressure and rolling the keg back and forth for 10 - 20mins with slippers on whilst watching the tv.
This way you don't overcarb the beer.
Bug said that with bare feet, you can feel when the bubbles stop so you know when to start rocking again, and that your mash tun cooler needs to be red.
Wayne, are you still out there?
