2. Fermentation Heater by The Weekend Brewer
We are quite impressed by the features of this Fermentation Heater by The Weekend Brewer. It is a flexible heater that is perfect for brewing Kombucha at home. It is also designed to help you brew beer and wine.
You just need to secure it around your bucket or carboy using electrical tape. For better control, simply pair it with a thermowell and digital temperature controller so that you can manage the temperature settings more precisely.

It is even designed to provide heat throughout the vessel. It keeps the fermenting liquid at the most appropriate temperature when paired with a digital temperature controller.
One feature of this heater that may not work in your favor is the wire connection to its thermal film seems to be weak. So, there are chances it may break easily. You need to be very careful and handle it delicately to ensure your device lasts longer.
This fermentation heater does not come with a thermowell and a temperature controller. So you will need to get those separately.
Priced at the budget level, we feel it is a good deal you can grab especially if you are a beginner and would not like to spend much initially.

It does offer a safe and effective heating system for the kombucha brewing vessels. It can increase the temperature of your brewing contents between 5° and 20° F above the ambient temperature. However, what most brewers may not like about this heater is you need to monitor the brew’s temperature with the help of the provided thermometer and adjust the heat accordingly. This means it lacks the automated temperature regulating system offered by advanced heating pads.
You can adhere the thermometer to the sides of the brewing vessel and then, increase or decrease the heat. To increase heat, you need to wrap the heating mat around the fermentation vessel and secure it with the provided rubber band.
If you feel the vessel has overheated, remove the heating pad and let it stand around the vessel forming a wall of heat. In this manner, you need to monitor the vessel so that the temperature is regulated throughout the fermenting process.

For those new to kombucha brewing, below is some background and further reading.
What is a kombucha heater and why do you need one?
A kombucha heater is a simple tool that helps you brew a perfect kombucha by maintaining the right temperature on a continuous basis.
We understand how difficult it can be to let your kombucha brew when the temperature drops. It seems it would take forever to brew your kombucha during winter months. Even if you do not mind waiting and are prepared to invest as much time as needed into brewing, the fluctuating temperature may spoil the contents and thus, would not yield the desired results.
This is why you need to maintain a constant temperature so that you can brew kombucha under controlled conditions. This would help to speed up the process and make sure the contents are not spoiled.
Ok, let me now reveal some ways by which kombucha heater would help you be better at brewing:
Your kombucha is likely to get infested with mold when the brew becomes too cold. Yeast may dominate your Kombucha brew thus causing the smell and flavors to be funky, musty, or even a bit strange.
And once the mold forms, all your efforts to brew kombucha would go down the drain.
Even if your kombucha is not particularly ruined by mold and yeast, the cold brew would surely lack the complexity and depth of flavors as the bacteria may have difficulty in producing the similar range of acids, which can contribute to the taste and health benefits of kombucha.
This is where a controlled temperature provided by kombucha heaters would be needed!
By maintaining the perfect temperatures, heating pads, wraps and mats enhance the flavors and the unique taste of kombucha.
Above all, they ensure no mold or yeast infests your brewing kombucha keeping it safe and healthy to consume.
However, it is important to make sure you choose the best kombucha heater so that the device is effective enough for providing the effect you are looking for.
How to use a Kombucha heater?
Kombucha heaters can help you brew Kombucha at the optimal temperature despite cold weather. You can also use the heaters to brew JUN, milk kefir, and water kefir.
You can choose to use a separate Kombucha heater for each ferment. However, since most of us Kombucha brewers do it as a part of healthy living lifestyle and not with any commercial interests, it is less likely that you need more than one heater. Hence, it may not be convenient to use a separate Kombucha heater for each ferment.
So, an alternative way is to use multiple small jars each of which is wrapped around the heaters or strips.
This can make it possible for you to have an entire slew of fermented veggies brewing at the same time with just one Kombucha heating pad or mat.
However, you also need to keep in mind that each ferment has its own preferred range of temperature. So, it may not be a good idea to brew all of them together at the same temperature. A viable option, in this case, would be to rotate the heating mats or pads.
For example, we know that heating Kombucha is the most critical step during the initial 7 to 8 days of one-gallon Batch Brew. If you are brewing 2.5 gallons of Kombucha Continuous Brew, you need to increase the duration of heating at a higher temperature to the first 10 to 21 days.
If you are on a break between 2 batches of the Continuous Brew or brewing a longer Batch Brew, you may “steal” the heater from the Kombucha to help with the other ferments, particularly those which require a short turnaround such as Milk Kefir and Water Kefir.
One thing you must remember while using a heating pad for Kombucha brewing is to boost the temperature after you have added to the booch.
For example; when you add sweet tea or JUN to the Kombucha, the heating mat must be re-attached to it. It should be set at a higher temperature close to at least 80°F or 27°C. In the case you have added Jun, set the temperature at 75°F or 24°C.
This would guarantee the bacteria and yeast a favorable environment needed by them to grow and ferment the brew. These bacteria and yeast would then be able to gobble up the nutrients they need from the sweet tea when they are exposed to a higher temperature. This would create a state of symbiosis for best results.
As you can see, it is all about setting the right temperature and regulating the environment so that you can brew your Kombucha in a way it ferments optimally and contains all the flavors you are looking forward to enjoying.
Second fermentation heating
Heating mats and wraps can be very useful during the colder months for improving the carbonation effect of the second ferment just before drinking. You can store the second ferment bottles in a cool surrounding to maintain its unique flavors.
However, though the carbonation usually comes out to be very good by the time you drink it, during winter, the bubbles may become too hard to come.
This is why you need to set it around the heater and give it at least 24 to 48 hours of warmth.
Most Kombucha heating mats can come in handy at this stage to warm the contents rapidly and kick up those bubbles without affecting the flavors.
Based on our assessment of these Kombucha heating pads, wraps, and mats, we found Kenley Fermentation Carboy Heater with Thermostat to be the best. It offers several features that can make it easier and convenient for you to brew a perfect Kombucha that has the unique taste and flavors you are looking for.
It is designed to maintain a controlled temperature throughout the vessel with an automated system to avoid overheating or cooling thus enhancing your brewing experience significantly.
What about (for a gallon brew) using a gatorade type cooler with an aquarium heater set to the correct temp? Keep the kombachu gallon just off the bottom and surrounded by the warmed water.
Gigi Mitts says
I’ve never done it that way. It sounds like it can work as long as you set the right temperature.
Stan, that sounds like a brilliant idea, to use an aquarium heater and have the kombucha bottle surrounded warm water. Did you try it, did it work?
