The new Rotokeg.
A nice big 4" neck barrel. Uses the standard valve and fits the cylinders we and most of the homebrew trade supplies.
It's strong and very well made. Holds about 51/2 gallons so there's room for storage of the natural Co2 !
It's a top tap which means it doesn't have to hang over the edge of the shelf. It can sit at the back.
It does mean you need a gas supply to get the beer out. The natural gas off the beer will dispense most of your beer but you do need to purchase either the s30 or the small injector that takes the small bulbs.
