Optional Pressure Lid
Add the optional pressure lid and turn your Fermentasaurus into a true uni tank. Uni tanks are conical fermenters used both for fermentation and for carbonating and serving finished beer. The assembly includes a lid with two ball lock connect fittings, a relief valve, and a unique floating pick up tube.  This pressure lid assembly turns the Fermentasaurus into the most unique fermenter on the market. Here are some possibilities:

Fermenting Under Pressure:
First one of the most intriguing uses is to ferment under pressure which reduces ester production and fusel alcohol production. That means that you can ferment warmer than you normally would, even making lagers at room temperature. Most commerical beer is fermented under pressure just due to the size of commercial tanks and the pressure that is created by the column of beer. It is one of the differences between commercial brewing and homebrewing. The lid has a built in relief valve that will blow at 35psi and we strongly recommend you also purchase an Adjustable Relief Valve, or spunding valve, that allows you to set a lower pressure. It is also always a good idea to have two relief valves on the Fermentasaurus anytime the unit is under pressure. 

Carbonating, Pushing, and Serving:
When you are fermenting under pressure the beer is already carbonated when you are done fermenting. You can control the level of carbonation by using an Adjustable Relief Valve.  You can use a Beer Line Assembly to sample at anytime. The idea is that the Fermentasauras can eliminate kegging and you can serve directly from the fermenter. We love this idea but there will probably still be times that you want to keg. Use a Keg Jumper line to connect the Fermentasauras to your keg and enjoy the easiest kegging experience ever.  You can also choose to send carbonated beer through a Beer Filter on the way to your keg.  When applying pressure with a CO2 tank also make sure that you have a functional relief valve on your CO2 regulator.  

Lack of Oxidation
Because the beer always has a CO2 blanket through fermentation and during any transfers out, oxidation is eliminated. When you cold crash you won't be sucking air back in through an airlock.  

The Fermentasauras was developed through a four year process of R&D. It is made from a special grade of PET, has a working pressure of 2.5 bar (35 psi). Additionally every single unit is tested in the factory to 8 bar (112 psi) before being released for sale. The Fermentasaurus needs to be hydro tested, or the PET body replaced, every two years. That test by date is printed on the fermenter.  Every unit comes with a set of safety instructions glued to the fermenter. You cannot expose the fermenter to liquids above 120F so for cleaning we recommend Craftmeister Alkaline Brewery Wash which can be used cold. You should also premix your chemicals to the manufacturers suggested dilution before pouring into the fermenter so that you are not pouring concentrated chemicals, such as Star San, directly onto the valve at the bottom.  

Key Features:
•    Ferment beer under pressure to reduce ester and fusel alcohol production
•    Ability to always draw clear beer with the unique, floating draw tube  
•    Keg already carbonated beer
•    Use co2 to push beer into a keg or though a filter into a keg
•    Carbonate and serve beer directly from the fermentasaurus, eliminating kegging all together

• Pressure Lid With Safety Release 
• Standard Ball-Lock CO₂ In Connection
• Standard Ball-Lock Beer Out Connection 
• Silicone Draw Tube
• Stainless Steel Float

These kits are not in stock yet but will ship out in July.

To ferment under pressure
Robert H on Jul 25, 2019
Hi if your making an ale and the fermentation temperature is around 72F wouldn't this mean you would need over 25 PSI of CO2 pressure to get it to about 2.5 vols of CO2 (based on carb charts) ? My question is, first am I correct on the PSI and second can the yeast/Fermentasaurus handle this ?
Gerard R on Dec 30, 2018
BEST ANSWER: While I think it’s rated for that high of pressure I don’t think it’s recommended. I’ve always had my spunding valve set at about 15 psi and forced carbed with bottled co2 while cold crashing.
Can the carb caps and the actual line and ball fit the fermzilla cap/lid? And the lid we know is a different size on fermentasaurus?
John S on Sep 12, 2019
BEST ANSWER: By reading the specs the fermzilla cap lid is bigger
making it easier to clean .
You could you use the line and ball to fit the fermzilla .
I bought this by mistake in anticipation of getting my new Fermzilla. Can it be used on the Fermzilla?
Ray Fuller on Aug 9, 2019
BEST ANSWER: Hi Ray. Unfortunately this is not compatible with the Fermzilla as the diameters of the opening are different. You will need FE134.
Will this work on FerMonster Carboy?
NATHAN POHLIT on Feb 8, 2019
BEST ANSWER: Hi Nathan - This product is not intended to be used with a FerMonster carboy.
How to measure SG in carbonated beer? I attached a picnic tap to the bev out so getting a sample is very easy, but it seems the carbonation from fermenting under pressure is causing spurious readings, both with the float hygrometer (which I expected) and also with a refractometer (which I did not). Has anyone figured this out?
Mark Parker on Jun 6, 2018
BEST ANSWER: You'll need to degas your beer to get a reading. If you have a flask and stir plate, pour the finished sample beer into a flask and let the stir bar remove any co2.

Fermenting under pressure, try it and like it!
This was the real reason to get the Fermentasarus, fermenting under pressure. 2 batches, 2 great results. I even bought a 2nd one. I will split my 15G batches between the 2 and do some dry hopping experiments. Couldn't be happier.

Get One
Price is right. Fermenting lagers at room temp under pressure. Cold crash in keezer with no ambient air suck back. closed system Rack to keg under pressure. Beer contacts no O2 until it hits your glass. F@ckin great

You gotta get this
If you have kegs you NEED this!

Clean and purge your keg with CO2, You can jump beer out on this and the keg, just release pressure on the keg and add pressure to the fermentasaurus (make sure your measurement sticker is spot on, cause you don’t want to overfill your keg)

Bonus is your wait time for carbonation is cut in half cause it’s already part way there.

Does not hold pressure
I have tested and tested....reset seals several times. I think there must be a faulty piece. Anytime I get up to around 25psi the seals blow and I lose pressure. Pretty annoyed....

Easy and Great!
The main reason I bought the fermentasaurus was to use the pressure kit. I also have a Fast ferment and this product is WAY BETTER. The floating pick-up is fantastic. I'm thinking of how I could modify one for my korny keg.
Highly recommended.

Fermentasuarus Pressure Kit
Not sure how well it is holding a seal. I am leaking pressure and everything is greased and tightened. I ruined a batch due to this issue, 2 of 5 stars. Hoping this is just a fluke and doesnt happen to next batch but overall not impressed at the moment.

I only put 20 psi and blew both the seals. I’m going to replace them and try another round. This time I will not have beer in it . Just a simple pressure test. Wish me luck
