What is a kombucha heating pad?

A kombucha heating pad or heating mat is a tool that allows you to control the temperature of the kombucha to prevent it from getting too cold. It helps keep the temperature at the optimal kombucha brewing temperature, which is around 75 ℉.

Benefits of using a kombucha heating pad

In cold locations, it can be a struggle to brew kombucha. The cold temperatures can cause a sluggish bacteria culture that may lead to longer fermentation, mold formation, and weak-tasting kombucha. 

Using kombucha heaters like heating pads or mats can help you reap the following benefits:

  • The consistent warm temperature helps keep the bacteria culture awake. It also allows the yeast to work at a normal pace – not too slow and not overactive. 
  • When the fermentation is at a normal pace, there is a balance between the beneficial bacteria culture, alcohol, and acids present in kombucha.
  • The perfect balance on temperature allows the second fermentation to build enough carbonation at the expected rate. Therefore, there will be no instances of exploding bottles or disappointment due to the lack of fizz on your drink. 
  • The taste will also be a good combination of sweet and tart with a kick compared to a weak or too sour taste.
  • Controlled heat also helps the yeast turn sugar into acids at an optimal level. The presence of acids in kombucha helps fight contaminants that cause molds. 

Questions to ask before buying a kombucha heating pad

While a kombucha heating pad can give a lot of benefits, you must consider some factors before buying one. Here are some questions to help you decide if buying a heating pad is a luxury or a necessity:

  • Do you often have mold problems when brewing your kombucha? Molds often form when due to contamination and slow fermentation. When the beneficial bacteria are sleepy and sluggish, they don’t form enough acids in kombucha that make it vulnerable to mold formation. If you keep on having mold on your brew, it’s better to buy a kombucha heating pad to keep the fermentation going.
  • Do you have an efficient HVAC system that heats the house well during winter, spring, and fall?`The cold seasons are a threat to your kombucha because they can jeopardize its quality. However, if you have an efficient heating system that keeps a consistent temperature indoors. You may no longer need a heating mat.
  • Do you live in locations that often have sudden fluctuations in temperature? Some areas experience different seasons in a day. If you live in one, brewing kombucha can be a struggle. So, having a heating pad can be justifiable. 
  • Do you live in a colder region? If your answer to this question is yes, Heating pads will be the best friend of your kombuchas. 
  • Does your second fermentation always fail to build carbonation? Second fermentation often needs to be above 75℉ to keep the yeast turning sugars into carbon dioxide. To achieve that, you can place the bottles in warmer areas of the home or, instead, buy a heating pad or mat to keep them in one place.
