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.

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.

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

Simple heater, no frills, no settings. Works as described

Great heat mat and as added bonus a thermometer strip. Fits almost around my 2 gallon jar. But that's ok, since no I can put the thermometer strip in between. I don't want to warm up my kombucha too much, since I can't drink it that fast :-). So I have it connected to a smart plug, where I keep it on longer at night (when we don't have the heat on) and shorter during the day (2 hours and 1 hour off at night, and 1 hour on and 2 hours off during the day). Energy consumption is low, 7.11 Watts at the moment. Also nice touch is the rubber band to keep it secured around the jar.

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.

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.

Love this heat mat, especially how it can wrap around the jar (with a rubber band to hold it in place). We like to leave the doors open when it is cool outside, but can be too cool for my kombucha batch so this speeds the process up and, from what I understand, reduces the risk of mold. The thermometer sticker is also super cool!
