The FastFerment Conical Fermenter Fermentation Jacket is an insulated, waterproof brewing accessory designed to maintain ideal fermentation temperatures for up to 8 gallons of liquid. Compatible with various fermenters and kegs, it allows for easy temperature control with minimal setup, ensuring your home brewing experience is both efficient and enjoyable.

## Description

How Does The Insulated Jacket Work? 1. The Insulated Jacket works great up to a 30 degree F drop below room temperature! 2. 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 below room 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! 3. A frozen 2-liter bottle typically does not thaw completely in 24 hours so it is easy to maintain a constant temperature drop.

## Questions & Answers

**Q: I have the catalyst 5 gallon. Will that fit in here? I think im might be a little too wide but im not sure**
A: I’m not sure if it will fit but it’s pretty wide. It fits over the fastferment 7.9 gallon with room both heighth and width wise. It insulates pretty well. Have you considered using the catalyst insulator?

**Q: What is it made of? What's the material?**
A: Outside is heavy ripstop nylon with velcro closures. I don't know what the insulation is.

**Q: What size is this looking for one that fits 14 gal model**
A: This listing fits the original 7.9 Gallon FastFerment.

**Q: Will this work with wall mounted fermenters?**
A: Yes, it is designed to work with velcroed slots. Needs to go on before the fermenter. You should try it out with an empty fermenter to see how it works.
