Cool Brewing Fermentation Bag

The Cool Brewing Fermentation Cooler is a great way to lower fermentation temperatures, while keeping costs low as well.  This insulated fermentation bag is designed to hold a 5, 6, or 6.5 gal fermenter along with airlock while fermenting.  By simply adding in bottles of ice from the freezer, you can see a 30° F drop in the bag from ambient temperatures.

Aside from working great to cool ferments during the summer, it functions just as well as a heated fermentation chamber during the colder months.  Pair the Cool Brewing Insulated Fermention Bag with a Fermwrap and temperature controller for precise heating control.

The Cool Brewing Bag has recently been further improved with the following updates:

1. Thicker Insulation. This not only helps maintain cooler temperatures better, but also makes the cooler more rigid to stand up better on its own.
2. A thicker internal liner. This helps keep the cooler even more durable as well as helping with temperature control.
3. A heavier duty zipper. Specifically designed to accommodate thicker insulation and liner for improved durability.
