The new and improved FermZilla in 27L brought to you by the critical minds and engineers behind the original Fermentasaurus Gen 1. Although the original Fermentasaurus was revolutionary at the time of its conception, there's always room for improvement. This is partly due to the strong community of Fermentasaurus users who have helped push for an improved conical unitank.

The FermZilla is the perfect option for brewers that want all the advantages of a conical fermenter without the price tag of a full blown stainless steel unit. It allows you to dump trub, harvest yeast, and with the addition of the 27L FermZilla Pressure Kit, you can carbonate and serve – all in one vessel! The clear PET tank allows you to visually monitor fermentation activity and is pressure rated to 2.4 Bar (34.8 psi), which means you can ferment under pressure, reducing ester and fusel alcohols in your finished beer. This also gives the ability to perform pressure transfers. If you prefer to move your finished beer to a keg or other vessel, you can do so with little to no oxygen exposure.
New and Improved:
1. Larger Dump Valve - 3" butterfly dump valve is more resistant to clogging from large amounts of trub
2. Larger Opening - 4.75" top port opening allows for easier cleaning
3. Less Headspace - more appropriately sized for 5-gallon batches. Purging the headspace of oxygen is easier and more effective.
What's Included:
  • FermZilla 27L Tank with Butterfly Dump Valve
  • Reinforced Stainless Steel Stand
  • Top Lid with PRV (35 psi)
  • 1000 ml Collection Container & Lid
  • 3-Piece Airlock
  • Graduation Sticker
  • Adhesive Thermometer
  • Strap Wrench
  • Spare Seals


  • 27 L (7.1 gal) Total Volume
  • Pressure Rated to 2.4 Bar (34.8 psi)
  • Temperature Rated to 122°F
  • Height in Stand - 28.3"
  • Height w/ Airlock - 32.7"
  • Tank Diameter - 13.9"
  • Diameter in Stand - 15.7"
  • Lid & Collection Container Ports - 28 mm PCO 1881 threads

Please note: when using the FermZilla under pressure, you must perform a water pressure check to ensure your connections are leak proof. To do this, fill your FermZilla up with water, apply at least 15 psi pressure, and check for leaks around all caps and threads.  

Pressure Stress
If you use the FermZilla to ferment under pressure, or you use CO2 to pressure transfer or force carbonate your finished beer, it is very important that you conduct semi-annual inspections of your tank. Even with perfect care, the FermZilla tank may show signs of wear from pressure stress over time. We recommend visually inspecting your tank for stress creases or other signs of wear once or twice a year. A hydro test should be conducted every two years, even if no signs of wear are found. The process is simple:

  • Fill the tank to the brim with water
  • Replace the Red PRV with a Green PRV rated to 4.5 BAR or higher
  • Pressurize the tank to 4 BAR (58 psi)
  • Check for leaks, then replace the Red PRV when finished

If leaks or potential points of failure are found, replace the tank before you continue using pressure with your FermZilla.

General Care
Taking good care of your FermZilla begins with cleaning and sanitizing the unit before and after use. The tank is made from food-grade PET, which is beautifully clear, but can be sensitive to long soaks in cleaners and acid-based sanitizers. In general, we do not recommend leaving products like PBW or StarSan soaking in the tank for more than an hour. Extended soaks have the potential to degrade the PET material and shorten the lifespan of the tank.

Having Trouble Removing The Lid?
The easiest way to take off the lid is to undo the lid ring then use a screw driver or faucet wrench to lever the lid up as shown in the animated GIF below:

so how would you take a hydro reading when under pressure?
Rick Runyan on May 9, 2019
Can you rack directly to bottles from this unit?
Tom DePoto on Aug 24, 2019
BEST ANSWER: Yes. It comes with a floating dip tube which will help keep trub outta your bottles. A good cold crash with compact the trub cake too.
Can this be taken off the stand and put in a fridge? Will the bottom support its weight? If not, is there a good way to keep the temp low?
Charles Richardson-Gongora on Apr 20, 2020
BEST ANSWER: Unfortunately you cannot take this unit off of the stand when it is full. It is entirely top heavy and cannot balance reliably on the collection ball or the valve. There are a few ways to keep it cool from inserts, huge fridges, jackets with icepacks, and a lot of other imaginative ways. Please explore our options on the website and see which option seems best for you.
will you do a funnel attachment for bottling that goes instead of the container?
Alex Hellbach on Oct 31, 2019
How do you transfer beer from the new style Fermzilla to a Cornielus keg?

Jeffrey L Palmer on Oct 14, 2019
BEST ANSWER: Pressure transfer with two psi differential work good with minimal forming. Example: 12 psi on the fermenter and 10 psi on the corny keg controlled by a spunding valve

I am a new home brewer and did my first brew yesterday. Should I leave gate valve open or closed during fermentation?
Frank W Colbert on Jan 3, 2021
BEST ANSWER: I leave it open to transfer wort. Chill to temp. Close the valve, dump the trub, close the valve. Clean and sanitize the collection container. Then re-attach the container and add the yeast. Then I let it completely ferment and you are ready to collect yeast if needed.
What do you need to buy in order to purge the collection can of oxygen for dry hopping?
Rob Sletten on Jan 23, 2020
BEST ANSWER: Hi Rob - You can use either our item #'s KG500 or FE133.
I'm thinking of using this for small batches (2-3 gal.). Will the excess headspace in this fermenter be okay for the beer?
Ben Geib on Sep 21, 2019
BEST ANSWER: It’s will be fine for 2-3 gallons, the previous generation(fermentasaurus) was a 9.25 gallons sized fermenter and was commonly used for 5 gallons batches. Granting you have a strong fermentation everything’s should be good.
Good luck!
Can you install a port on the lid that will fit the BrewBuilt CoolStix?
Gabriel Burgos on Apr 18, 2020
BEST ANSWER: The coolstix looks like it would need a 1” bulkhead fitting. Morebeer sells a Temp Twister Cooling Coil complete with bulkhead fittings that would easily fit and made for the Fermzilla. It is relatively inexpensive. You can still install the pressure kit and thermowell for temperature sensing.
How do you use the FermWrap with the Fermzilla and the Insulating Jacket? I thought the Fermzilla couldn't use a heater because it's plastic.

BEST ANSWER: I would not use the FermWrap. It is too wide to fit the FermZilla and it is rated at 40 watt. Kegland suggests under 30 watt is safe. I used 4" wide reptile heat wrap for my FermZilla. That is 22 watts and I have had no problems.
could mason jar be used as a container?
Alex Hellbach on Oct 31, 2019
BEST ANSWER: The trub/yeast collection cup at the bottom of the fermenter is much larger in diameter than even a wide mouth mason jar. It has a different thread, and sports two additional ports on opposite sides. (See photo)
what are the dimensions without the stand?
Moises Celaya on Aug 5, 2021
BEST ANSWER: This unit is 28” top to bottom. (No fermentation lock installed.) Diameter of 13”.
What is a suitable PRV for the Pressure Stress test?
David Dooley on Jan 8, 2021
BEST ANSWER: The 'hydro test' procedure is not very well documented to my knowlege, so I personally completely understand this question. Here's what I've personally come up with, FWIW.

First, the stock PRV Pressure is 35psi and the instruction manual found on the manufacturer's website repeatedly warns against exceeding 35psi. My conclusion is that a full pressure test of the vessel would mean testing it to 35psi. To hydro test I fill the vessel with the collection jar attached and the butterfly valve open with circa 2gals of water and approved soap (PBW) solution. Next, I attach a CO2 bottle with the pressure set to 0psi. I start adding pressure with 10psi and then increase by 5psi at at time until the vessel reaches 35psi, stopping between each pressure step to allow the vessel to settle. Once the vessel has reached 35psi, I verify that the prv is releasing pressure and opening. I do not ever exceed 35psi and my PRV has always opened at this pressure.

I do not keep the vessel at this pressure for long. I do not ferment anywhere near this pressure, so to reduce stress on the vessel, I next reduce the vessel pressure to 24psi and look for any leaks. After a few minutes, I lift the vessel from the stand and carefully turn it upside down and place it back into the stand upside down I let it sit for 10 minutes or so and verify that there are no leaks.

A couple of maybe helpful tips and safety items: 1 - Wear safety glasses or goggles! On one of my vessels, the collection jar blew a peice out of the side of it at about 20psi during the first hydro test and the polycarbonate piece left the vessel at an insane speed. Morebeer quickly replaced the defective collection jar.

2 - I would recommend hydro testing the unit in a garage type wash tub, if you have one. If your vessel experienced a rare pressure failure, water will go everywhere, but most will go down the drain.

I hope this was a helpful answer!
I would like to purchase (separately) two of the stainless ballocks like the ones that come with the pressure kit. Are these available and if so what is the cost? Thank you.
Jeffrey L Palmer on Oct 27, 2019
BEST ANSWER: Hello Jeffrey, the ball lock fittings are currently not sold separately.
Do you sell collection containers separate? I just broke mine because it's difficult to unscrew from bottom.

Can I use my Fermentasaurus pressure kit with femzilla?same size lid?
Chris Robertson on Aug 23, 2019
BEST ANSWER: Hi Chris, no as the lid of the Fermzilla is wider than the Fermtentasaurus. The lids on the Fermzilla's come fixed with the body connect threads and are covered by plastic caps. The Fermzilla Pressure Kit includes the body connects to install on the existing Fermzilla lid, the stainless float, and silicone dip tube.
Can I put boiling wort into this? At one point I thought I heard you can do this? Trying to save time on chilling.
Scott Childs on Aug 9, 2019
BEST ANSWER: Hi Scott - the FermZilla's tank is made from PET and temperature rated to 122°F. However, a PEN replacement tank, which will withstand temperatures up to 212­°F, is in development and will be available soon.
What Temp Control options are available for this? And when will they be available?
Oscar Garcia on Jul 5, 2019
BEST ANSWER: Hi Oscar - We do not carry temp control products specifically designed for the Fermzilla, however, we do carry the Fermentasaurus Jacket and FermWrap fermentation heater.
Does anyone know if there will be a thermowell option and CIP (clean in place) option as well?
Jack Carlos Slovenski on May 30, 2019
BEST ANSWER: Actually, KegLand recently released a video on how to install a thermowell in the Fermzilla. I can post the link here, but just Google "Fermzilla thermowell" videos, or search on YouTube
Are ball lock fittings included with the top?

How Did Life Exist Before Fermzilla?!??
This fermentation vessel is easy to assemble, set up, clean and use. Once you start pressure fermentation, you will never want to go back. I love how easy this is to clean with a little PBW solution and a microfiber cloth.

You will help yourself out tremendously by downloading and reading the assembly and use instructions prior to receiving your vessel. Perhaps several times. Here's a couple of use and cleaning tips I've found to be helpful:

1. Do NOT over tighten anything. No need to go gorilla on any part. I have two of these. My first, absolutely no leaks, hand tightening all items only. However, on my second vessel, the small port caps on the collection jar leaked whether using the bottle caps or carbonation caps. A couple wraps of teflon tape on the threads solved this problem rather effectively.

2. I do not completely dissassemble the vessel between brews, reserving complete dissassembly for every 6-10 fermentation cycles. I brew once or twice a week and I have had no contamination issues using this method. I thorougly clean and hydro test for leaks every time, but I do not fully dissassemble except occasionaly as stated above.

3. Before you assemble, work the butterfly valve several times from fully closed to fully open. They tend to be really, really tight at first and may be difficult to close fully if you do not work the valve before you put it into use.

4. Watch your Krausen height. If it comes into contact with the PRV, remove and clean the PRV as soon as possible or it may not operate properly.

5. Use the belt wrench that comes with the vessel to loosen only. There is no need to go gorilla on tightening any part of the vessel when assembing it. However, you will be glad you have the belt wrench tool when you disassemble.

6. Get some keg lube or use pure petroleum jelly (which is what keg lube actually is) on threads and seals occasionally per the manufacturer instructions. Petroleum jelly is food safe and approved for contact with food. It is non-toxic and can be purchased in greater quantity for less cost than Keg Lube. However, if you are skeptical of this recommendation, get genuine keg lube. You don't need very much at all and one tube will last you for years.

Since I started using pressure fermentation with the Fermzilla, my beer consistency is much better, I keg the beer with closed transfer, which prevents the finished beer from coming into any contact with oxygen until it exits my kegerator and enters my glass. This has resulted in a greater shelf life to my homebrew. My family and beer tasting friends have noticed that my already kid tested and mother approved beer has improved noticeably for the better. It is smoother, clearer and crisper. I do not filter my beer, but everyone believes I do because it is so beautiful in a clear glass.

Sorry for the book! I love using these fermentation vessels! Thank you MoreBeer!!

So far so good!
Have used the fermzilla twice now & am reasonably happy with it. Dry hopping was a bit of a challenge. I’m pressure fermenting & getting the collection container off without making a big mess has been interesting. Pressure transfers to keg are super easy. The ability to see what’s going on at all times is a big plus. For the money it does what it’s supposed to do. Definitely get a pressure transfer kit & spunding valve kit & be careful not to let off pressure too quickly or you’ll have a mess.

Great Fermenter, with Caveats.
Moving on from my dependable Fermonster carboys, I purchased the FermZilla hoping I could reduce or eliminate transfers and oxygen exposure and be able to remove trub and hop residue and add dry hops through the collection jar and butterfly valve. I purchased the pressure kit, though I didn't think I would be using gas right away. I intended to continue bottling for the time being, figuring I could somehow use gravity to move finished beer into bottles.

I was wrong. After trying various means to use gravity for bottling, none of which worked well, I gave in and purchased the equipment I would need for pressure transfers. With that, I set up a beer out line running to my bottle filler, applied a few PSI of pressure, and tried bottling that way, with limited success (lots of foaming issues, even though the beer was not yet carbonated). With my current batch, I gave up on bottling altogether after filling two 22 oz bottles with mostly foam. I'm now trying to force carbonate and serve directly from the FermZilla, but so far I am getting only foam when I try to dispense. I am now in the process of ordering the equipment I need to keg my beer.

So, after my initial investment in the FermZilla and pressure kit, I spent about the same amount again purchasing the CO2 tank, regulator, and other pieces I would need to use gas pressure. And now I am about to drop around the same dollar amount again to purchase the kegging equipment.

The bottom line: If you are not ready to begin using CO2 and pressure, this is really not the fermenter for you. If you want to continue bottling using gravity, stick with something like the Fermonster. FermZilla will not work that way, not well anyway.
For that matter, if you intend to continue bottling at all, this is not the fermenter for you. Gravity won't really work without significant risk of oxidation. And pushing the beer to your bottle filler with even a minimal amount of gas pressure invites foaming issues in every bottle, even is you cold crash first.
If you are ready to use gas pressure to protect your brews from oxygen exposure, perhaps even to ferment under pressure, FermZilla works well for these things. If you are ready to abandon bottling and move to kegging your beer, FermZilla is an excellent choice, enabling you to do completely closed transfers to kegs. You just need to be ready to go all-in on using CO2 and on kegging your beer. If you're not ready to go all-in, ultimately tripling your overall expenditure, stick with simpler and much cheaper alternatives such as the Fermonster.

I should have saved up for a stainless
Decent for the price point but as a new brewer, with guidance from experienced brewers, I was a bit disappointed.
A bit difficult to assemble and nearly impossible to disassemble for cleaning.
I tried to dump the yeast and trub near the end of my fermentation just before leaving town for a couple days. Upon my return I found a puddle of beer on the floor. Apparently the force i had to use to open the gate created a small break in the seal. Not all was wasted but still a pain.
Another design flaw is that you can't set the fermzilla down without the stand. My wife became annoyed having to follow me around with the stand as I moved it from garage to basement and back to garage for kegging.
