Good news! If you have detected that there is a deposit at the bottom of the bottle, you should know that it is a sign of the health of your kombucha. It is the natural yeasts that have contributed to the production of the kombucha bubbles. It has a peculiar taste, but it brings many health benefits.
The solid substance that you can find in the neck of the bottle is the mother of kombucha, or mini-scoby. Serve it with care or drink it without fear because it is full of B vitamins!
In any case, we advise you not to shake the bottles if you do not want to end up bathed in kombucha.
