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 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 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 (Pre-Assembled & Attached)
  • 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)
  • Height in Stand - 28.3"
  • Height w/ Airlock - 32.7"
  • Tank Diameter - 13.9"
  • Diameter in Stand - 15.7"

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.

Does this come with the pressure kit lid?
Du Tran on Mar 14, 2019
BEST ANSWER: Hello Du - At this time with the product still in development, we are unsure if a pressure lid will be included as standard. Contact has been made with the manufacturer for confirmation.

Can you purge the Collection Container?
Ryan White on Jun 27, 2019
BEST ANSWER: Hi Ryan - Is purging referenced in regards to dry hopping? If so, take a look at this thread on the subject: https://www.homebrewtalk.com/forum/threads/easiest-way-to-purge-hops-with-co2-using-a-fermentasaurus.648512/
so how would you take a hydro reading when under pressure?
Rick Runyan on May 9, 2019
BEST ANSWER: Hi Rick - The floating dip tube is connected to the bev out post, so you can use a picnic tap or something of the like to take a sample.
Can you install a test port like you can on the fast fermenter?
Rick Runyan on May 5, 2019
BEST ANSWER: Hi Rick - The plastic on the Fermzilla is too thin to install a test port.
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: Hi Jack - Currently there is not an option for a thermowell and CIP ball for this fermenter.
Are ball lock fittings included with the top?
Brian on Jul 11, 2019

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.
Will there be a jacket for this like the original fermentasaurus? Or will that jacket work with this?
Andrew Wayland on Feb 2, 2019
BEST ANSWER: Hi Andrew - The FE106 will not fit on the Fermentasaurus Gen 2, but there will be a jacket specifically made for the Gen 2 that should be purchasable when the Gen 2 becomes available.
Can I put boiling wort into this? At one point I thought I heard you can do this? Trying to save time on chilling.

27L FermZilla
I have so far fermented 1 5gal batch and transferred it to the Keg (under pressure!) and have a second batch fermenting right now. I am pleased with it and have not found any drawbacks so far.

Great Product
I've been using fermentasuras for over a year.
oversized for 5 gallon batch. this is perfect less head space, easier to handle, seems more stable. Fits better in keezer and larger collection jar and opening make clearing easier.

Quality product at a good price
The only reason I purchased this was because I could do pressure ferments without having to spend a fortune. After receiving it I realize that I can now pressure transfer my wine that is fermented in it as well.

Grab 2+ Stainless Steel carbonation caps from Morebeer and replace a top plastic one and a bottom plastic one. Then you can just pop up a ball lock and transfer with zero oxygen getting to your product.

Top is a tad hard to get off and the bottom is downright difficult but they sent a tool to help.

The base is also slightly too big for my freezer fermentor (5 Cubic Feet) by an inch which kind of sucks.

An Improvement
An improvement overall. The only thing I am worried about is the flatter slope at the bottom. The previous model had the problem of sediment accumulating on the shoulders and the unit had to be rocked back and forth to allow sediment to go into the drain. With the new flatter configuration it looks like that a lot more rocking will be needed.
