The FastFerment™ insulation jacket is designed to maintain the optimal brewing and winemaking temperature. It is compatible with wall mounts and the stand, allows easy access to the thermometer, and keeps the airlock visible thanks to its two zippers. The jacket is made of durable nylon on the outside and waterproof insulating fabric on the inside. It has a diameter of 52 cm and a height of 86 cm.

To lower the temperature in the fermenter, frozen water bottles can be used:

1.4 °C: 1 bottle of 1 liter
2.8 °C: 1 bottle of 2 liters
5.6 °C: 2 bottles of 2 liters
8.3 °C: 3 bottles of 2 liters

A 2-liter bottle typically takes more than 24 hours to fully thaw, ensuring a consistent temperature drop.

Note: The original wall mounts of the first-generation FastFerment fermenter are not suitable for use with the jacket. Use the stand or order wall mounts with pre-drilled holes if necessary.

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, they are available separately (item no. 140.560).
