## Overview

The FastFerment Conical Fermenter Jacket is an insulated, waterproof cooler bag designed to maintain ideal fermentation temperatures up to 30°F below ambient. Compatible with fermenters and kegs up to 8 gallons, it uses frozen 2-liter bottles for scalable cooling, requires no assembly, and features a handy side pocket for temperature monitoring. Perfect for home brewers seeking consistent, professional-quality results.

## 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.

Review: great
Review: Bought this to use with a standard fermentation bucket rather than FastFerment vessel. Its overly large for the purpose - could probably fit a pressure barrel in there too. But the main point is that the idea works really well. I don't believe there are any other similar solutions on the market either. By daily swapping out of plastic bottles of frozen water I have been able to keep the temperature of my last 2 home brew beer batches to an optimum level despite an ambient temperature in the room of around 26 degrees.

## 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.

### ⭐⭐⭐⭐⭐ Review
*by N***K on 24 August 2020*

I use a cooling coil and pump with my 5 gallon Spike Brewing conical, and I was having trouble keeping it at temperature with a bucket of glycol in my freezer. I wanted to avoid spending nearly a grand on a glycol chiller, and I didn't want to spend a few hundred on a AC glycol chiller build either. With my Spike Conical in this insulator, all the temperature control issues went away. I can crash down to 35 degrees no problem, and I was surprised how well it fit.
