The FastFerment Insulated Jacket is an affordable system that allows you to create the ideal temperature for your brewing and wine making in FastFerment. In hot climates, add 2 liter bottles of ice to cool it down, switching them out every 2-5 days. In cold climates, simply add a heating pad. This jacket works with the FastFerment stand and wall mounts.

How Does the Insulated Jacket Work?
The insulated jacket works great up to a 30 degrees F drop below room temperature
It is easy to control the desired temperature by using frozen 2-liter bottles as follows:
One frozen 1-liter bottle will result in a 2.5 degree F drop below room temperature
One frozen 2-liter bottle will result in a 5 degree F drop over below temperature
Two frozen 2-liter bottles will result in a 10 degree F drop below room temperature
Three frozen 2-liter bottles will result in a 15 degree F drop below room temperature
This method is scalable all the way up to around a 30 degree F drop below room temperature
A frozen 2-liter bottle typically does not thaw completely in 24 hours so it is easy to maintain a constant temperature drop
The following graph highlights a lager fermented at 53 degrees F in a 68 degree F room
For this test, 3 frozen 2-liter bottles were cycled every 24-36 hours
