The original and we believe still the best and most convenient way to add gas to your home brew keg. Screws straight onto the top of the standard (non pin) original s30 valve to add extra gas to your keg. Co2 cylinders are an optional item. Depending on how long the beer is in the barrel determines whether you will need to use one. Initially, you prime the barrel with granulated sugar, glucose or malt extract. This gives the necessary secondary fermentation. Possible half way down the barrel a vacuum occurs (no beer comes out of the tap or the beer gets lazy), it is at this stage a Co2 cylinder is used to ensure the beer stays fresh right down to the last pint.
For in store collection only. Gas cylinders can not be shipped.
