Kombucha Heater | Fermentaholics Kombucha Brewing and Fermentation Heat Mat | Keep Your SCOBY Happy and Productive by Brewing in The Proper Temperature Range

Great product. Keeps my kombucha between 76.8-77.8. Perfect brewing temperature. Fits my 2 gallon glass brewing jars perfectly. They are preset so no need to adjust temperature.

We got mold on one of our earlier batches. The internet suggested it might be because our kitchen is too cold. Since we wrapped our continuous brew jugs with these we have not had that issue again. Had to figure out a better “stay-put” than a rubber band (we used garden stake velcro). But, the mat has helped our booch stay nice and happy

Perfect for my half gallon and 1 gallon jars of kombucha. The rubber band it comes with to wrap this around your jar doesn't work well, so I use a clip instead. The thermometer it came with broke after a week. The wrap is super simple. Nothing to do but wrap it around your jar, plug it in, your done. When it's cold in my house, I wrap a tea towel around the jar too after the heat wrap is secured on.

After struggling for a while trying to get kombucha going I purchased this heat mat. It made a huge difference for my kombucha. This is the second mat I've ordered. I have used my first mat for a couple of years now. I just wrap it around my gallon jar and it keeps my kombucha at about 82 degrees. My SCOBY is so much happier. Also, the site has lots of helpful information.

This is a great product for kombaucha brewing

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.

It does not fit around a 1 gallon glass kombucha brewing jar. It’s does not secure. They send you a janky black rubber band to keep it secured around the jar. It doesn’t hold it at all. Save your money.

I am having trouble with this one (as have many others who have bought it. ) It doesn't hug the fermenting jar as it should, and as a result, it doesn't heat up much. I am looking for something that will warm up the brew in cold weather the way it does in warm weather. Tired of waiting 3 weeks! Wondering what to try next.
