The 35L Conical Fermenter

A complete package with the fermenter and 23L premium keg package

The Fermentasaurus With Our 23L Premium Keg Package... Just perfect!

  • Our motto at iKegger has always been "forget bottling".
  • We have made it our mission to take out the labour and headaches involved with that process and now we are taking it up a notch and simplifying the fermentation process too!
  • These AUSTRALIAN MADE fermenters are genuine UniTanks as they combine a lot of steps into one simple process and vessel.

Watch How To Do A Brew Start To Finish Using A Fermentasaurus

The Problem With Buckets

  • Transfers between containers equals more chances for infection or oxygen contact.
  • Trub (sediment) is in contact with your brew in the bucket and can alter flavour of beer if it's left sitting too long so you generally transfer the brew into a secondary vessel (bottling bucket etc) and then from there into bottles or kegs.
  • Yeast is generally wasted as it's difficult to collect for re-use without contact with air / contamination.
  • You always need to carbonate brew after primary fermentation via force carbonation or secondary fermentation.

How Does A Conical Differ?

  • With a conical there are no transfers.
  • The sediment all settles into a collection jar for easy removal.
  • You can save the yeast for your next brew or dump it out.
  • Your brew isn't sitting on the yeast sediment so you can leave it in the fermenter indefinetely until ready to bottle or keg.
  • You can replace the yeast collection bottle with the included barb outlet to fill your clarified beer directly into kegs or bottles.

What's The Pressure Kit?

  • Brewing under pressure speeds up brewing and also reduces ester production.
  • Using a spunding valve to adjust the pressure during fermentation the brew will be carbonated once primary fermentation is complete.
  • The floating dip tube means you can draw the brew from the clearest part, the top.
  • You can attach a tap and regulator exactly as you would to a keg and serve directly from the fermenter.
  • You can transfer to keg using gas pressure with no contact with the air in minutes.

Fermentasaurus Conical Fermenter - 35L Uni Tank With Optional Ball Lock Posts

Overall experience using this item is good. Purchased during EOFY sale. A little slower being posted than a previous purchase. Minor problem with PRV not holding pressure that was dealt with very quickly with a replacement being sent to me. So easy to check on progress of first brew. Transferring the finished product was also so easy.

Awsome delivery time.

Delivery of the Fermentasaurus was quick and in one piece considering the distance, it had to travel. The ease of use is just great and with the uni tank ball locks we will fill our 5 ltr kegs direct.

Super quick shipping and updates. I'm new to brewing, but found the fermentasaurus really easy to use. The only thing is I forgot to buy the pressure spunding valve. But they helped me straight away online to realise what I needed. Great system! Looking forward to using it more, cheers


Great item

Great item and very helpful team at iKegger. I’m very impressed with their speed at answering enquires and getting orders sent out!
