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.

I had already purchased the Fermentasaurus and I wanted a way to carbonate directly in the fermenter without having to rack.

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.

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

Best fermenter I have !!
Great idea I have done several bees in this and never got them to keg. I just crash my fridge carbonate and hook a tap to it. The floating ball that pulls the beer from the top is also a great idea. I ordered 3 for my kegs very reasonable.

I like the ease of fermenting with this unit, like the idea of using pressure.

This fermenter does everything it's supposed to do,it works great. Kinda hard to clean. The airlock is very fragile and is slightly different from typical airlock .mine cracked the first time I used it. Going to have to get another airlick.

Bought 3 with pressure kits around Oct. '17; made 6 batches of 7 gallons approx. but initially in Fermonsters and did not really ferment under pressure even with the "Saurus" yet. We want bottles not kegs so far, have so much we can't drink it so will have to wait before further efforts and experiments. 3-400 bottles in freezers @ 34F. My "crowd" not craft beer aficionados; want it clear, bottled, no sediment,lager. My first effort since student days (ughh!), ordered IPS type ale kits; finally learned a simple all-grain american wheat beer. Would have liked much more detailed instructions on pressure aspects. Problems have been not knowing how to use the pressure relief safety valve; All three of mine blow at 9 to 15 psi not at 35 psi so I tried to plug them. My 2 spunding valves only go 0-15 psi and came without instruccions. I guess "everyone knows" how to adjust them (except me). Trial & error, much YouTube; finally got CO2. there weren't even explanations of the little "toilet tank float". Guess if you're intelligent no explanation is required, it's obvious. If you're not, no explanation is possible. These days most tools come with 6 pages telling you not to plug it in while sitting in the bathtub, and 4 lines on use and technique. So many options. Whether to rack to a clean vessel. Can't filter carbonated beer. Bottling carbonated beer. I did fairly well with simple wands but next season will get a bottling gun and a counter-pressure outfit. Oh, I had problems with leaks around blow-off valve and worse with the gas and liquid quick-connects, Again no education that the black and the gray plastic connectors are not the same. I got 3 Brewjacket immersion coolers; worked with Fermonsters but impossible with the crowded pressure head of Fersmentasaurus. Maybe those clever New Zealanders will mold a special adaptor cap with lateral side connectors so I could do everything truly single conical. Meanwhile 7.2 cu. ft. freezers came on sale here at a certain store for $130. Work great with $35 Inkbird controller. Have to build insulated height extenders to pressure ferment etc. with Fermentasaurus under really controlled cold. Actually I plan to put 2 Fermentasaurus pressurized systems in each freezer. Problem? design to enable lifting 9 gallon conical and all its glorious accessories in and out. Even 5 gallons a risky strain for near 81 year old. HF has hydraulic lift table works well up to table height. A special Fermentsaurus harness and mini-forklift anyone? I had no leakage from the cap threads above or the bottle, spigot, seals below. Have nice white food-grade synthetic grease but guess Crisco or mineral oil fine.
