Really simple. All the effort has already been done. This includes the milling of the grains, the weighing of the hops, mashing in, sparging, the boil with the hop additions, etc. The only thing left for the brewer to do is to ferment the wort into beer.
For the beginner with no equipment, the kit allows this to be done all-in-one, without the need of a fermenting vessel, an airlock, etc. The kit, along with the pressure release cap, was designed to allow fermentation to be done inside the cube itself. All you have to do is to break the seal on the cube, pitch the yeast into the cube and screw on the pressure release cap. Let the beer (it is called “beer” once you add the yeast to the wort) sit at room temperature, in a dark area (like your pantry) for 10 to 14 days and your beer is ready to be bottled.
Once the beer is ready to be bottled, you just sanitize some bottles (empty soft drink bottles, sanitised with something like Jik or a special solution like Milton’s, work really well), add a bit of sugar to each bottle and pour in your beer. Seal the bottles, let them sit for a week and your beer is ready!
For the more experience brewers, the wort can be handled just like any other wort made at home. It can be poured into a fermenting vessel, fermenting using your favourite style-specific yeast at the correct temperature in your fermentation chamber. It can be clarified, filtered, lagered and kegged, if you would prefer.
