Need an economical way to keep your 7.9 gallon FastFerment 15° to 30° cooler than the surrounding air in Summer? This cooling jacket features interior loops to hold 2 liter plastic soda bottles that you freeze. The idea is you have 3 or more 2 liter plastic soda bottles filled with water, and freeze them. Rotate them in and out of the cooling jacket to keep your beer cold 24 hours a day. Use from 1 to 6 two liter bottles depending on the temperature drop desired. The minimum temperature drop is achieved with one frozen 2 liter bottle.
This becomes fairly heavy when you add 3 or more frozen 2 liter soda bottles to the inside. Because of this, we do not recommend you use the older style wall brackets (sold before mid 2015), as they may fail due to the heavier weight. See the pdf of the instructions below for more on this. This works very well with the floor stand.
