Adjustable Kombucha Heat Mat - Bucha Brewers Kombucha Heating Wrap, Kombucha Warmer, Fermenter Heater

The temperature piece was missing when I received my mat. I contacted customer service by email and two days later I received two new ones in the mail. That was fast! The mat has a dial to adjust the heat as I brew my kombucha. It took a few tries to get it where I needed it but now I know where that setting is things are going great. So appreciative of good customer service.

I am so happy with this kombucha heating mat, I now own four of them for all of my kombucha brews! I live in Alaska and must rely on a heating mat to maintain the appropriate and consistent brewing temperature. Temperature is the key for successful kombucha brewing and this mat has an adjusting dial so I can tweak the temp slightly up or down, as needed, instead of only offering a high/low setting like other mats on the market. EXCELLENT quality for the price!

Everything works. The rubber bands they include to secure the heating pad around the gallon jar snapped the next day. Otherwise good product.The heating pad has a dial to control temp but no other indicator as to where on the range you are such as a notch on the dial.So as to not kill my scobies, I started off at the lowest dial setting and worked up.

Absolutely love my Kombucha mat!! The mat has 3 heat adjustment settings which is awesome. Make sure to plug in and feel the backside of the mat to make sure it's working. I mistakenly thought it was broken and reordered a replacement when there was absolutely nothing wrong with the mat. I had placed the mat on the jar and then felt the outside of the mat which was still cool and wrongly thought there was an issue and ordered a replacement. It's ok though, I realized my mistake and contacted customer service (excellent service btw) and paid for the replacement, which was a win since I do two different types of Kombucha and also water'kefir'. These are awesome and worth every penny. The Kombucha heat mat has helped take my fermenting to a whole new level of good. Planning on ordering a couple more!! Thank you Buca mats for making such a great mat and thank you Amazon for amazing customer service..win! Win!

Update: I found out some things, thanks to comments from users on other similar products. I have granite countertops. Granite will act as a heat sink (oops). I originally had the jar on a wood cutting board but apparently this isn't enough to counteract the granite. I solved this problem by putting my jar on a seed starter heat mat as well as having the wrap around mat on the jar. Now the wrap around is doing its job okay. I upgraded to three stars (just okay) because it does heat my jar. I still don't like the temp controller. There are absolutely no markings to indicate where high, medium or low might be. There luckily was a note in the instructions that said to turn dial until it clicked (that is Off), then turn it all the way on (High) and reduce by turning the dial back toward off according to the temp strip. So not great, but will works if you check your brew daily. I am seeing that even with the bottom sed starter heat mat, I have to keep this wrap mat on High to achieve 75-80 degrees.After two days on High my gallon kombucha jar still reads 72 degrees according to the heat strip. That's what it read out of the box. This is in a warm house, so doubt this unit would work at all in a colder room. The heat mat is warm to touch, so working, but the lack of really any meaningful temperature control or range makes this one sub optimal for me. I will keep and see if it works as a seed starter maybe. Caveat, I am new to kombucha brewing and this mat is on a second fermentation jar so it's possible I am doing something wrong. I will be looking for a unit with a digital temp control.

I keep the house at a pretty low temperature in the winter while I’m at work, which isn’t good for kombucha making. My brews turned out pretty bad for a few weeks while brewing them at about 64 degrees during the day. This may helped so much! I love that it’s fully adjustable. Just be sure to buy extra stick-on thermometer strips so you can monitor the temperature of your brew.

I'm happy with this heat mat. It gets the job done and is easy to clean. In my experience it won't work if it is too cold. My basement is about 55 degrees this time of year and the mat has to be set on high to keep the kombucha at 72°.

Warms kombucha during brewing. No numbers on thermostat. Otherwise satisfactory.
