I brewed this Biermuncher recipe 9 days ago, Had a FG of 1004 reading at day 7 and again today. I think I'm ready to keg it. I don' want to force carb it, so if I got this right, keg the beer, purge the keg, put it in the fridge to get down to serving temp ( would say about a day) then hook up gas line to keg, set to 10/12psi until it stop filling... my question is do I leave the gas line hooked up or disconnect it and let it go.... Thx in advance...
