The Fermenter King Jr

The Fermenter

  • The 20L Fermenter Keg Jr is a great small batch fermenter and keg in one.
  • Include a spunding valve and your brew will be carbonated when it finishes fermenting!
  • Perfect for a fresh wort kit, the easiest way to brew good beer.
  • It can be used as a start to finish brewing vessel capable of being pressurised up to 35psi
  • If it is too large for your fridge just get a smaller keg with a ball lock spear and transfer the brew to it as needed.
  • You can transfer the same tap and regulator to any of our other mini kegs and growlers
  • It has standard ball lock gas and liquid posts and a 35psi pressure release valve.
  • It can also be used in the place of steel 19 & 20L kegs
  • 259.4mm (width at base) 586.9mm (height to top of posts)
  • It is great for camping etc as it's 1/4 the weight of a steel keg and can be used lying on its side thanks to a floating dip tube.

The Insulated Backpack

  • The JetKeg insulated backpack is great for day to day use as it both protects the keg and stops the beer getting light struck (light and beer are not friends).
  • It is waterproof so you can put ice in it to chill or keep your keg cold and has pockets designed to hold either a sodastream gas bottle or 16g bulbs to dispense your drink.
  • If you want to take beer somewhere with you it is also a strong backpack with padded straps (and it and the keg together weigh less than 2kg when empty).
  • When fermenting you can use it to help keep your fermentation temperature steady

Love it

Having previously had issues with my corny kegs leaking, I decided to give the juniors a try and I absolutely love them, I pressure transfer so I can see how much is in them, they hold pressure, lightweight and the post fittings seem to connect seamlessly, I have 2 and will in the future get some more. Love them
