Review: Much needed addition to your home brewing kit. - Heats good and consistent. Low profile so it's easy to watch/monitor your batch of kombucha. Works well on the 2 gallon size too. Only draw back is having to use a rubber band to hold the heater around the jar.
Review: Versatile for using with kombucha, sourdough, keifer, and more. - This is our 2nd mat! I bought one because my kombucha would mold in winter when house is cooler than 70 degrees. I just lay it flat in the closet and set my kombucha and keifer on top. It is perfect. So when my daughter was struggling with her kombucha and sourdough, I bought her one. She said it is a gamechanger for her sourdough bread. She puts it in her oven overnight. The oven light was too hot but this mat is perfect.

## Features

- ★ SAFE, EFFECTIVE HEATING ★ Offers efficient heating for your kombucha brewing vessel. Ideal temperature range for kombucha is between 75° and 85° F
- ★ MAKE PERFECT KOMBUCHA ★ Fermenting at too low of a temperature is the #1 mistake new kombucha brewers make. Don’t let this be you!
- ★ ADHESIVE THERMOMETER INCLUDED ★ Monitor the fermentation temperature by adhering the provided thermometer to the side of the brew vessel and adjust the position of the mat if needed.
- ★ EASY TO USE ★ Instructions are printed right on the heater—no chance of loosing them! Just plug it in and start raising the temperature of your kombucha between 5° and 20° F over ambient temperature. Vary the strength by adjusting the heater's placement.
- ★ FERMENTATION FRIEND ★ While this works great for kombucha, it also works for your other home fermentations that need a little temperature boost such as kefir, sourdough, sauerkraut, kimchi, tempeh, etc!

### ⭐⭐⭐⭐⭐ Gets the job done
*by T***N on June 20, 2023*

This seems to keep the kombucha at an acceptable temperature, although I think being able to select what one believes to be the perfect temperature would be great. I wish this had variable temperature control, not only to select what I think is perfect but to also maintain a narrow temperature range. From what I can see, it keeps the liquid about 15 degrees warmer than the ambient temperature. I would love to keep mine within a few degrees, but because of this, it has a range of about nine degrees, because my home ranges that much. Again, it gets the job done so I have no complaints, but it would be nice to control it myself. Definitely worth the money and not worth returning to get one with control. Highly recommended if you want to set it and forget it, which certainly does have its appeal! I metered it and at sixteen cents a kilowatt hour, it costs about two cents a day to run. Also, the cord is quite long at right about six feet, which is nice.
