FermZilla Conical Fermenter - 13.2 gal. / 55 L

60 day no hassle return policy. Details

The new and improved 55L FermZilla 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 55L FermZilla Pressure Kit (available in both stainless and plastic), you can carbonate and serve – all in one vessel! The clear PET tank allows you to visually monitor fermenation 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 you 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 10-gallon batches. Purging the headspace of oxygen is easier and more effective.
What's Included:
  • FermZilla 55L 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


  • 55 L (13.2 gal) Total Volume
  • Pressure Rated to 2.4 Bar (34.8 psi)
  • Temperature Rated to 122°F
  • Height in Stand - 40.1"
  • Height w/ Airlock - 43.5"
  • 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.

Love making ginger beer, more effective way to keep sediment out of my beer when bottling. I always make two 5 gallon batches so this is the petty size to dedicate for my ginger beer 🍺

Are the lids and the pressure kits for the Fermentasurus and the Fermzilla the same?
Brady Wolden on Dec 10, 2019
BEST ANSWER: Hello Brady, no the lids aren't the same. They are different.

Was great until last night when it violently exploded
I have brewed 3 times with the FermZilla, and up until now it has been fantastic. The engineering of the product is truly remarkable. If anything, it should have warnings that you should not tighten things to a normal degree. Everything fits superbly with minimum force. Unfortunately, that might have contributed to last night's explosion. I isolated the yeast harvester with the dump valve and was letting it finish settling overnight. (Disconnecting the yeast harvester makes a yeasty mess consistently.) At some point the yeast demonstrated their might and created so much pressure in this small vessel that it exploded, sending yeast across the garage and shards of ?polycarbonate? in a smaller blast radius. Fortunately, the 10 gallons of beer is still pristine and the garage smells great . . . for now.

DO NOT UNDERESTIMATE THE MIGHT OF YEAST! Do not close the dump valve for more than a few hours if there is yeast in the collector! The dump valve is truly air tight and water tight.
Beware the power of yeast. Pressure can be dangerous.

Nice product
Arrived assembled just needed some minor tightening. A little disappointed that the plastic is not thicker but it serves a purpose just fine.

Love It
I wanted to get back into brewing and found this gem. I read a lot of complaints about leaks, but I have not had any trouble. First ferment is a Mead, but cannot wait to use for beer. I look forward to pressure fermenting and even running glycol cooling through it. Lots of options. Thanks too whom ever created this masterpiece.

Kevin - Thanks for the feedback. These are wonderful when you add pressure capability.

Great as a Multi-tank
This vessel is amazing, so far 2 brews in it.
For as inexpensive as it is, it is so capable.
I would like to see a bit thicker plastic, as it is pretty flimsy when not pressurized, and this can be a pain as it wants to crumple when trying to take off the trub collection parts (those things really do require the removal tool!)
I am going to pursue a replacement cap, as the pressure relief valve seems to leak.

Leaking Lid
I have tried several attempts to get the lid not to leak when fermenting under pressure. I purchased another lid but still leaking. I have the Fermentasaurus and no leak problems.

Looks good so far BUT does not come with SS Handle
In the Video on Kegland for this product they show how they were going to have integrated plastic handles, but they found the quality to be lacking and did not want people to drop it so they "went back to the drawing board" to redesign it with SS handles. Even the Instructions shows the SS Handles. The Video they said it made the cost a little more but it was worth it for the quality. Then it comes and says that the SS handles are an accessory. Morebeer does not even have this listed as an accessory Even Kegland has it listed as FermZilla - Replacement 304 Stainless Steel Handle
In Stock
$12.95 Meaning Replacement... Not accessory.
This I found to be very disappointing. I don't blame Morebeer at all. I will be putting this on Keglands page too.
