Guinness or other already nitro-infused cans or bottles:simply pour these into our keg and dispense with CO2 or N2O through a stout spout. If using a regulator and CO2: you will need a higher than normal pressure to push it through the spout so remember to turn it down and release some pressure before leaving it to sit or you will over-carbonate the beer. If using our nitro spear: You can just inject a bulb of N2O and pour, be aware that leaving the stout in the keg with high-pressure N2O will affect the texture if left too long. It is better just to put what you will drink in one session into the keg when filling from cans or bottles.

Non-nitro infused cans or bottles of stout / porter (and carbonated homebrew): If you want to get nitro style stout you need the nitro injector spear. Pour the beer into the keg and then inject a couple of nitro bulbs, let sit for a couple of hours or gently swirl /rock the keg for 10-15 mins to absorb the nitro into the beer. After that pour using the description above for nitro-infused beer.
