I've never left a keg for a long period of time without being hooked up on gas. I recently brewed a lager that I am leaving in the fermentation chamber at 32F for 4-5 weeks. I kegged it and pressurized to 30 psi to seal the lid while it lagers. Is this amount of pressure going to carbonate the beer at all or will it all absorb and break the lid on the seal? I'm trying to avoid moving the keg to hit it with more gas within the 4-5 weeks so I don't agitate the sediment. I suppose I could pull a pint with the picnic tap first if I needed to add more gas?
