The perfect brewing temperature for Kombucha is 22-27°C 19-20°C is at the low end of ideal brewing. 10-18°C this range causes very slow fermentation with weak or yeasty flavours and the possibility of mould.
If you find your brew sitting below 20°C I would recommend helping your Scoby with some external heat.
This adjustable 7 Watt heating mat can increase your brew by few degrees (about 3-4°C above your room temperature) depending on the ambient temperature and the brew size. Just place your brew on top of your Heat Mat.
Features: Heat Mat distributes Heat evenly Extra thin design with maximum flexibility. Their shape sees a greater concentration of heat in a more defined location.

Great kick start to my booch in colder months. Won’t be needing it this summer though!
Great unit once you find the sweet spot 24-25 degrees low wattage and you don’t have to watch it
1) The electric cord from the mat does not sit snugly into the adapter. 2) The mat feels warm & even though the temperature is set to its warmest, the temperature strip shows that the brew (at its warmest) has reached 21 degrees.
Great for keeping the batch regulated as the spring temperatures in Perth are a bit unpredictable
I purchased the heat pad for my Kombucha as I couldn't get the temp past 16, it is now sitting comfortably on 21-22. I am looking fwd to completing this batch and many more to come.
I am very happy I bought the heat pad and would also like to comment on the excellent customer service over the phone and emails. Judy.
It works very wellKeeps my kombucha in safe temperature.
The brewing is much quicker now, almost half the time since I started using the heat mat it's ready in 10 days instead of over 3 weeks and the Scoby has more than doubled in size.
Expectations met, good price, excellent quality, delivered on time.
The 4lt kombucha jar is the perfect starter size. Nice design and perfectly functional for it's purpose. All Karl Kombucha products have surpassed expectation.
I'm very happy with everything I've bought and making lots of Kombucha
Excellent this time my kombucha is working with the heat
This is great for keeping the brew warm. However I found I also needed to wrap a towel around the jar to keep it warm enough.
Quick delivery. A Godsend for my Scoby in the middle of winter.
Great purchase and reasonably priced. The item was delivered very quickly and was well wrapped. I'd definitely recommend this seller.
Our brew wouldn’t go over 16c and was almost dormant. The heater mat has got us brewing at 23c and getting great results. Well worth the money.
Great product. Easier than the wrap, I was using, (which I got an electric shock off)
Item supplied as described in good working order with no problems.
Just added a heat mat to my set up and wow. Within 24 hours things changed. Just bottled and flavoured my 1st batch and brewing my 2nd
Already brewed, works a dream, love this company!
As a first time brewer the process was so easy. I have had no failures and have and have just received my second 8l jar. very happy. taste delicious
only criticism I have is that there are no real markings to show on or off.
Trial and error to figure out when it clicks if off or on high.
I used a permanent marker to show preferred setting.
Flexible enough to wrap around the jar if needed but I use it on an insulated placemat (flat)
Works very well in my cold climate.
Made such a difference for ferment time of my Kombucha, and even managed a fizzy F1.
I have a 4L jar from Karl so I can even fit a couple of my F2 bottles on the end of the mat to give them a headstart before I refrigerate them.
Very happy with the heat mat, however the power connection is quite loose and has to be watched carefully in case it falls out.
Works very well. The temperature increased to around 23/24 degrees.
Great product. Instructions very clear.
it is a pleasant and easy experience dealing with karl............ i'll be back
So glad I purchased the heating pad with my starter kit. Without it, I imagine brewing would be difficult during Tassie's winter.
The mat heats quite gently and, at only 7W, won't use too much power. It may take a while to get my 8L container up to brewing temperature, and then I can play with the heat control to keep it steady.
I just wish we could lose the EU plug+AU adapter. Although it seems to be OK as it is, even a Chinese plug (upside down AU) could make it more stable in the power point.
Products are of excellent quality, service was prompt and efficient, prices very reasonable.
This is the perfect heating pad for my brew. Love this company for its personal service and great products. Simply everything you need for making your own Kombucha.
The heat mat makes kombucha taste fantastic. It makes it really bubbly.
A must have in colder winter climates like mine!
We have decanted 2 ltrs. 4 times since purchasing the 8 ltr. kit and all is working very well. We add some fresh ginger and lemon juice to the decanted liquid and let rest for 3-4 days, the taste is terrific.
We have just received the heating mat so that will make the system easier to use.
Thank you for your product and your service.
Cheers Geoff & Eva.
