I recently started kegging and I started out just putting them on the gas and waiting a few weeks. I'd get perfectly carbonated beer but I can only fit two kegs in my fridge along with the co2 tank so I started cask carbonating in order to put a ready to drink keg in the fridge when one runs out. Problem is these are usually overcarbonated gushers where nothing but foam comes out of the tap, yet the beer is virtually flat. I've used the full recommended amount all the way down to half the recommended amount of priming sugar with the same results. Does anyone use this method successfully? Any tips would be helpful.
