Add this optional pressure kit to your FermZilla 27L and turn your FermZilla into a true unitank. Unitanks are conical fermenters used both for fermentation and for carbonating and serving finished beer. This is the stainless version, there is also a plastic option.
This extremely inexpensive upgrade will truly show you what the FermZilla was designed for. Here are some possibilities:
Fermenting Under Pressure:
First one of the most intriguing uses is to ferment under pressure which reduces ester production and fusel alcohol production. That means that you can ferment warmer than you normally would, even making lagers at room temperature. Most commercial beer is fermented under pressure just due to the size of commercial tanks and the pressure that is created by the column of beer. It is one of the differences between commercial brewing and homebrewing. The lid has a built in relief valve that will blow at 35psi and we strongly recommend you also purchase an adjustable pressure relief valve, or blow tie kit, that allows you to set a lower pressure. It is also a good idea to have two relief valves on the FermZilla anytime the unit is under pressure.
Carbonating, Pushing, and Serving:
When you are fermenting under pressure the beer is already carbonated when you are done fermenting. You can control the level of carbonation by using an adjustable pressure relief. The idea is that the FermZilla can eliminate kegging and you can serve directly from the fermenter. We love this idea but there will probably still be times that you want to keg. Use a beer line to connect the FermZilla to your keg and enjoy the easiest kegging experience ever. You can also choose to send carbonated beer through a beer filter on the way to your keg. When applying pressure with a CO2 tank also make sure that you have a functional relief valve on your CO2 regulator.
Lack of Oxidation
Because the beer always has a CO2 blanket through fermentation and during any transfers out, oxidation is eliminated. When you cold crash you won't be sucking air back in through an airlock.
Key Features:
- Ferment beer under pressure to reduce ester and fusel alcohol production
- Ability to always draw clear beer with the unique, floating draw tube
- Keg already carbonated beer
- Use co2 to push beer into a keg or though a filter into a keg
- Carbonate and serve beer directly from the FermZilla, eliminating kegging all together If you need replacement parts for the pressure kit, it is made up of a Silicone Float and Dip Tube and two Carbonation and Line Cleaning Caps.
