beer styles. In order to perform pressure fermentation, you will need to purchase the following
additional parts:
-
2 x Carbonation caps. We would advise getting one red plastic carbonation cap (
and one yellow carbonation cap so you can differentiate which carbonation cap has the dip
tube attached to it.
-
1 x Silicone dip tube with stainless float (
-
1 x Duotight
–
Blowtie 2 Spunding Valve (
) or Blowtie Spunding Valve kit (
).
This blowtie spunding valve should be set at your desired fermentation pressure and should not be
set above 35psi. When the vessel is under pressure
do not
expose it to temperatures greater than
35
°
C (95
°
F).
When fermenting under pressure you must not close the butterfly valve during fermentation if you
have wort in the collection vessel which has not finished fermenting. Only close the butterfly valve
once fermentation has ceased and hydrometer readings are stable for 3 consecutive days.
When removing the collection container for example when dumping trub or yeast make sure to
open the butterfly valve and ensure the system (including the collection container) is depressurized
prior to removing the collection container.
Pressure Transfers:
Easily avoid oxygen getting into your beer and staling it prematurely by transferring under CO
2
pressure in a closed loop system straight to your kegs! Oxygen is the enemy of beer, by going
straight from the floating dip tube on the FermZilla to the liquid post on your keg, you can be sure
your precious beer won’t come into any contact with the outside out.
A pressure transfer will require an external CO
2
source such as a CO
2
cylinder(
and a MK4 regulator (
) and mini 360 core actuator
regulator (
).
It is best to attach a spunding valve to the gas (IN) post of the keg and set a small pressure difference
between the FermZilla and keg at the start of the pressure transfer to avoid excess foaming of the
beer during the transfer. Later in the pressure transfer you can increase the pressure difference
between the keg and FermZilla by opening the spunding valve further to release more pressure.
