New to the forum but have been brewing for some years now and just now starting to keg. So my question is basically when serving do I keep co2 hooked up. My setup is. Right now keg is in fridge at 40 and co2 at 10 psi. It's been on for two days. Now 10 psi is to much pressure to serve at. So do I disconnect co2 and let it come from tap that way or do I leave co2 on and lower to 2 psi and serve like that. Thanks.
