FermZilla All Rounder 30L Starter Kit | Pressure Fermenter

The FermZilla All Rounder 30L Starter Kit is an affordable, pressure-capable PET fermenter designed for home brewers. With a working volume of 20–25 litres, it's the ideal fermenter for brewers using systems like the Grainfather G30, Speidel Braumeister 20, BrewZilla 35L, Brewtools B40, or Brew Monk 30L. In combination with the optional pressure kit, you can turn the FermZilla All Rounder into a true unitank – perfect for fermenting under pressure and carbonating your beer in the same vessel.

Thanks to its compact size, the FermZilla fits in most fridges. With a CO₂ source and a tap connected via an NC coupler, you can even serve your beer straight from the tank – no need to transfer! Alternatively, you can pressure-transfer your beer to stainless steel kegs (KEGs) using a daisy-chain transfer kit without exposing it to oxygen.

The clear, durable PET construction allows you to watch yeast activity in real time, and the wide 12 cm opening makes both filling and manual cleaning quick and easy. The included stainless steel stand provides extra stability. If you're into temperature-controlled fermentation, the FermZilla All Rounder is compatible with accessories like the FermZilla Twister Cooling Coil, Thermowell, and Special Pressure Lid – allowing you to connect your glycol chiller (e.g., Lindr AS-40).

PLEASE NOTE Before using the FermZilla under pressure for the first time, we recommend performing a pressure test with water at 1 bar to check for leaks. Keep in mind that the FermZilla is not designed for bottling and does not include a tap. However, with a counter-pressure filler (e.g., iTap), you can bottle your beer directly from the FermZilla – check our blog post for a full guide. Alternatively, you can use a racking cane from the top.

IMPORTANT SAFETY INFORMATION Please read the instruction manual before first use! The FermZilla cannot be returned or exchanged if it has been misused or handled incorrectly. Do not exceed 50°C with liquids inside. When using the FermZilla under pressure, do not exceed 0.4 bar at fermentation temperatures of 35°C or higher. Always keep the tank away from direct sunlight. The manufacturer recommends a pressure test every two years when using the FermZilla under pressure. The tank has a printed expiry date related to pressure rating (this is not a best-before date!). After that date, you should re-test according to the instructions (we recommend method 3b). If the test is successful, you can continue using the tank as usual. Please note: slight dents or deformations from shipping or handling do not affect the integrity of the FermZilla. The tank is designed to tolerate minor warping, even under vacuum during cold crashing. Once pressure is reapplied, the tank usually returns to its original shape.
