Best for price: Fermentaholics fermentation heater

Buy on Amazon

Next on the list, we've got yet another heater that manages to win our hearts. It's the fermentaholics fermentation heater and it's widely considered as heater that has the most suitable features. Temperature plays one of the most important roles in your kombucha brewing process, from affecting the fermentation time to the flavor. It works well for 1 or 2 gallon vessels. If you move the heating pad from the bottom of the jar to the middle of the jar it will definitely raise the temp. The box comes with all the info you'll need to know to get your heat mat up and running with your brew in no time. Wraps perfectly around a 1 gallon glass jar, the rubber band keeps it in place nicely.

The room temperature has been only 60°F some days, so fermentation wouldn’t occur without this mat. This would be a much better product if it has an adjustable Velcro closure so that it can fit any jar and securely instead of loosely with a rubber band. It also works well with all other favorite fermentations like kefir, sourdough, kimchi, sauerkraut, and more. The mat rolls up easily for storage when not in use.

Why We Like This:

Works very well with a couple tricks
Great heat mat and as added bonus a thermometer strip
Nice touch is the rubber band to keep it secured around the jar

Best for fermentation fridge: Propagate Pro fermentation heater

Buy on Amazon

The propagate pro fermentation heater is capable of outshining several other heater featured in this list in overall features in its price range. It's really sized for a 5 gallon bucket. The heat pad alone is able to maintain temperatures in the mid 70's for a 5 gallon plastic pail with 4 gallons of must. The pad itself is about a foot in diameter, so you can probably do a couple bottles. The temperature is steady and accurate.

The heater definitely works pretty well with a simple plug and put under a fermenting bucket. The mat is big enough to keep a 6 quart tub warm in a kitchen that can drop to 58 F overnight. It does not heat up very hot at all though. It is going to be marketed for home brewing, and the probe should be constructed to be waterproof.

Why We Like This:

Gentle heat so you don’t raise the temperature too high
A must own product for wine and mead fermentation
Works well with carboy plastic bucket as well as kombucha momma set up

Best for fermentation chamber: Raincol fermentation heater

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate heater. The raincol fermentation heater is exactly that - it's a simple heater that hits all the right notes. It is designed to wrap around the "exterior" surface of a bucket or carboy. It fits a 10" diameter vessel. The length of the turquoise section is 31 and 1/2 inches of which about 3 inches are not heated. It makes malt/milk too hot especially when room temperature is higher than 74 degrees. It is important to match the temperature sensor above the belt to prevent over heating. It will maintain at a constant brewing temperature.

The belt gets pretty warm (guessing 95 to 110 degrees) hot to the touch but not burning. It is a continual temperature, so if you want to warm up the carboy/primary pail slip to bottom.

Why We Like This:

Perfect for kombucha making in the winter
Wonderful for kombucha fermentation in glass container
Keeps temperature elevated so fermentation can complete
