How does the Insulated Jacket work?
It is easy to control the desired temperature by using frozen 1- & 2-litre bottles as follows:
|
Temperature drop
|
Frozen ice bottles required
|
|
1.4°C
|
1 x 1-litre bottle
|
|
2.8°C
|
1 x 2-litre bottle
|
|
5.6°C
|
2 x 2-litre bottles
|
|
8.3°C
|
3 x 2-litre bottles
|
This method is scalable all the way up to around a 17°C drop below room temperature!
A frozen 2-litre bottle typically does not thaw completely in 24 hours so it is easy to maintain a constant temperature drop.
The graph (see product images) highlights a lager fermented at 12°C in a 20°C room. For this test, 3 frozen 2-litre bottles were cycled every 24-36 hours.
In cool climates, simply add a non-electrical heating pad.
Watch the video for user instructions.
Remark: FastFerments come with the correct Wall Mounts for using the Insulated Jacket. However if you have an original first generation FastFerment, the Wall Mounts do not have the pre-drilled holes and are not reinforced for the additional load. In that case use the stand or order the Wall mounts with pre-drilled holes.
