## Overview

The FASTFERMENT Conical Fermenter Jacket is a sleek, insulated, and waterproof fermentation cooler designed to fit up to 8 gallons. Using frozen 2-liter bottles, it enables precise temperature drops up to 30°F below ambient, ensuring optimal brewing and winemaking conditions. Compatible with a wide range of fermenters and kegs, it requires no assembly and features handy side pockets for temperature monitoring, making it an essential accessory for serious home brewers.

## 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.
