Description

The Fermentasaurus is a unique, game changing plastic conical fermenter for homebrewing. It is the perfect choice if you want to see your fermentation, dump trub, collect yeast, and even carbonate all in one vessel without any transfers or siphons.  Made from clear PET the Fermentasauras offers the classic benefits of a conical shape without the cost of stainless. It will drastically cut down on oxidation by removing any need to rack your beer to a secondary vessel. And perhaps most amazingly it can be pressurized like a keg with the addition of the optional Fermentasaurus pressure kit

The Fermentasaurus fermenter has a large 35L (9.25 gallons) size that makes it easy to ferment 5 gallon batches. The standard lid has a built in stopper and comes with an airlock. There is a butterfly dump valve at the base of the cone with a 500 ml harvesting container. This makes it very simple to remove the yeast at the bottom of your fermenter without exposing your beer to oxygen. The handy harvesting container also allows you to store the yeast to use on your next batch! The dump valve has been designed so that no threads are immersed in liquid making it easy to clean. Other fermenters will use ball valves that are very difficult to clean without completely disassembling them.

The Fermentasaurus is produced in Australia after four years of R&D. This fermenter is the world's first conical PET fermenter that is pressurizable up to 2.4 Bar (34.8 psi) letting you go from fermenting to serving without having to transfer to another vessel. You also have the option of fermenting under pressure which reduces esters and fusel alcohols allowing you to ferment warmer than you normally would. If you do choose to transfer your beer you can do it under pressure straight into a keg or other vessel with little to no oxygen exposure. 

Features:

  • 9.25G/35L total volume
  • Clear and easy to see through
  • Screw top lid with airlock
  • Butterfly dump valve 
  • 500 ml collection ball below dump valve
  • 304 stainless steel frame with carrying handles

  • Temperature rated from 32-131°F (0-55°C)
  • Rated for 2.4 Bar (34.8 psi) working pressure when used with optional pressure kit (Do not pressurize the Fermentasaurus without the pressure kit, FE101)

Dimensions:

  • Total height with airlock - 37.6 in.
  • Total diameter - 14.9 in.
  • Tank height - 27.1 in.
  • Tank diameter - 13.5 in.

Overall value. I'm not quite ready to splurge on a stainless unitank , yet the Fermentasaurus will allow me to pressurize my beer by force. I'm also hoping the create a carb stone attachment for this device.

Can I use PBW to clean the fermentasaurus?
Matthew on Jan 13, 2018
BEST ANSWER: Yes, I’ve been using it to clean my fermentasouraus. There is no need to let it soak over night though because you are able to fit your arm and and in to gently rub the gunk off.
any video or instructions on cleaning the fermentasaurus especially the butterfly valve after use?

I bought a 2nd as a gift
I preordered mine when they first became available. I have fermented too many times to count and always happy. Five stars of course but several times I did not tighten the tank to valve connection and had to tighten to stop drips. Not a problem, since once tight enough the leak stops. I now tighten another 1/8 turn beyond what I believe is tight and problem seems resolved.
Good size, easy to clean, pitching and removing yeast in the conical bottle make this superior to carboy bottles or buckets. A good step up for me after 30 years using carboys.

So happy with my purchase!
I got this with the pressure kit and a spunding valve, I set it around 8 PSI for all my brews. 6 brews and I haven’t had a bad batch, not having to transfer (reduced chance of bacteria and O2) and can move directly to a keg (reduced chance of bacteria and O2) the beer is sterile and never touches oxygen once I pitch the yeast.

It’s easy to clean (even after sitting for a few weeks after kegging)

My suggestion is just BUY IT!

First brew in fermentasaurus
Great conical for the price. It is nice to be able to view fermentation. Only gave 4stars because the airlock wouldn’t seal. I realized the airlock hole is used for the pressure relief valve on the pressure kit and there is not a gasket to seal it. Did a hack on the lid to add a thermowell and an elbow for a blowoff tube.

Save your money if you can- get a stainless!
I was disappointed in this. The plastic is thin- you can easily "crinkle" the plastic inwards with negative pressure. Also- if you fill it and plan on moving afterward- be very careful! It is very awkward to carry this thing with 5 gallons in it!

I would say it does MORE than the the other plastic fermentors out there (like, pressurized options the being the biggest) but after $120 for this, and $60 for the pressure, kit, you are almost halfway there to a real stainless!

I returned mine- HUGE kudos to MoreBeer's AWESOME customer service! It makes me feel confident buying knowing that these guys & gals stand behind their service and products. Added an extra star for that.

lower adapter dissassembly advice
LOVE the fermenter. Bought a second one.
Adivice to those taking the lower assembly apart.
get a strap wrench and part number 1000012510 from home depot. (internal pipe wrench set, 3pc.) The largest handle fits into the hex opening of the adapter perfectly. Much easier to take apart. Rememeber it is left hand threaded. Don't forget to put some keg lube very lightly on the washer and O-rings during ressembly.
Happy Fermentations!

Best fermenter ever!
Awesome! First day removed trub, after a week Removed a bottle of yeast. Later removed another bottle and a half of yeast. Pitched the yeast directly into another batch and had active fermentation in a few hours. After first batch finished fermenting, transfered into a keg, super easy, cleaner than any batch I have ever made. This thing is great.

Great product!
I bought this primarily to ferment under pressure and it is great for that, but it is also great in general. I have a Fast Ferment as well and this is a far superior product. The only thing I would change is a larger butterfly valve. I have some trub hanging up in the conical and not falling into the bottle.
Would buy it again in a heart beat. Highly recommended.

Looks like good inexpensive fermenter
I have mead fermenting in it right now. The unit appears well made for the price. Only negative is the stand, really cheap. They should offer an upgraded stand. Would be willing to pay more for it. This fermenter is really good for mead as mead ties up a fermenter for a long time. Will have to see how the mead turns out to fully eval this.
