But what does ‘on tap’ mean? In its most simplified form, ‘on tap’ is synonymous with draught beer. Using kegs with a tap has three main principles. The first is sealing the beer from contamination with the outside environment, the second is allowing compressed gas in to force beer through the tube and thirdly allows smooth exit of the beer.
The whole draught system is designed to connect the keg to the tap, to ensure a quality poured beer whilst still making it taste great. It is a delicate balance of keg pressure, resistance imposed by tubing, and hardware such as faucets and couplers. Traditional draught systems also require a lot of maintenance!
However, the clever design of The SUB means draughting at home is a whole lot easier. With the sleek compact dispenser, not only can you tap beers at home any time you like, but you needn’t worry about pressure, C02 and hardware!
