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

20 Ltd. King junior

Have bought 2 juniors now. The best way to brew beer. Have tried all the other ways, bottles, kegs. This is the best way and the easiest way. Extra fast delivery. Great people to deal with.

FKJ 20L Fermenter

Great unit own 3. Great price $100 total with a spunding valve for pressure fermenting. Fairly robust and easy to clean. Easy to carry. Would be good if it was 23L as with 2nd fermenting and kegging to get the perfect amount in my 19l kegs. But overall very happy.
