Fermentation Heater Belt


About This Product

Our Heater Belt will fit around small and large vessels to keep your Kombucha, Yogurt or Kefir warm while it’s fermenting.  Stretch and place the O-Ring band around the belt over the FRONT END of the belt.  Adjust it so the belt is tight around the fermenting vessel you’re using.   If your vessel is extremely wide, you can eliminate the O-Ring band and use the entire belt by tightening the END NEAR THE CORD.  Adjust the height of the belt on your vessel above or below or in-between the contents to maintain the desired temperature. Our testing using a 3-5 gallon container showed the belt did not raise the liquid above 89f (31.6c). You'll need to monitor your vessel and adjust accordingly. 

Note: Kombucha prefers the warmer temperature range of 75-90f, while milk or water Kefir prefers a range of 65-75f. Yogurt needs to ferment initially at 105-110f/40.5-43.3c). You can use the belt to help modulate the temperature drop of your yogurt. Includes instructional sheet.

Our Heater Belt is available with our Kefir and Kombucha products at a discounted price.
