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.

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.
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:
