I only have space for two kegs in my kegerator so I am kegging up some brews for a party in 3 weeks. I hooked up one last night at @ 28.5 psi per tasty brew. It does not give a time frame as to how long it will take to carb. Any one know the answer? can I bump up the psi to get it to carb faster, kinda like force carbing but at room temps?
