To measure the temperature during kombucha production, a self-adhesive thermometer can be a very convenient option. This type of thermometer can be stuck directly onto the jar where the kombucha is fermenting, allowing you to monitor the temperature continuously and without interruption.

Temperature is a crucial factor in kombucha fermentation, as it influences the activity of the microorganisms responsible for fermentation. Maintaining the temperature within the ideal range, generally between 23°C and 27°C, is essential for fermentation.

Adhesive thermometers offer a practical way to track this variable, but it's important to note that they may not provide readings as precise as more advanced thermometers. Therefore, for more controlled and professional production, it may be advisable to consider other, more accurate thermometer options.
