The Fermenter King Jr


  • The 20L Fermenter Keg Jr is a great small batch fermenter and keg in one.
  • Dimensions : 259.4mm Wide at base. 586.9mm height to top of the posts.
  • Include a spunding valve and your brew will be carbonated when it finishes fermenting!
  • We recommend using hop filter  attached to floating dip tube.
  • Perfect for a fresh wort or ready brewing kits , 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
  • See the insulated backpack (JetKeg Insulated Bag)
  • 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
  • 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


  • Buy without a tap to use as a fermenter, a storage keg or to use it in a kegerator where you would usually use 19L kegs.
  • Alternatively attach a tap and serve direct from the keg.
  • The pluto gun is an easy and cheap option that also allows you to use the keg while it is lying on its side.
  • The flow control stainless tap is a premium bar style beer tap that allows you to slow the flow of liquid, which is handy if its pouring a little foamy.
  • Both tap options also include a mini regulator with a sodastream bottle adapter on a remote gas line
  • You can use either 16g CO2 bulbs or a 400g Sodastream bottle to carbonate or dispense your drinks with this system (gas source not included)

Einfach & Gut

Der Behälter macht den Umgang mit dem Jungbier deutlich einfacher, da der Sauerstoffeintrag und der Aufwand deutlich verringert werden. Ich nutze das System sehr gerne.
