This Is Awesome!
Heavy duty foil lined insulation that completely encloses the Fermzilla,
This insulating jacket is a useful addition to your 30 litre FermZilla All Rounder , it ensures that the fermentation temperature remains at the same level during the cold winter months. The insulating effect ensures that the heat generated by the fermentation is retained within the jacket. If the fermentation reaches too high a temperature, you can easily lower the temperature by adding a few frozen bottles or ice packs inside the insulation jacket.
The jacket has the added benefit of being completely light tight, which protects from harmful UV lights and prevents light stuck beer.
This seems very well made and we are really impressed with the quality of them.
These jackets are excellent quality. I keep my fermzilla fermenters in. my shed where the temperature can get pretty cold at night. I use fermenter heat belts to keep the beer at the proper temperature. The insulation jackets make this a lot easier to do, they contain the heat from the belt regulating the temperature so I don't have to set the temperature so high. They also hold the natural heat created from the fermentation. Come summer I am going to pack the insulation jackets with bags of ice I will let you know how that works out.
