All the facts on shelf life and storage of the fermented tea drink

Unpasteurized vs. pasteurized kombucha

We exclusively sell unpasteurized kombucha. For a very simple reason! During pasteurization, the tea drink is heated. In the process, it loses almost all of its valuable nutrients and probiotic bacteria. In the end, it's still a refreshing drink, but nothing more than a soft drink.

How long does homemade kombucha last? How do I store the fermented tea drink?

For homemade kombucha, a general shelf life of nine months cannot be given. After bottling, the fermentation process does not automatically stop. From time to time, kombucha becomes a little sourer and gets more effervescent natural carbonation. Kombucha can also spoil or be contaminated by unwanted microorganisms. Therefore, the drink should be stored as cool and dark as possible. This is best done in the refrigerator or in a cold cellar room. Here it is exposed to only a few external influences and can be stored undisturbed. The shelf life can thus be extended for some time. By constant cooling, the fermentation is delayed, and it slowly becomes a little sourer.

Watch out!

Some large kombucha manufacturers pasteurize their drinks and add artificial probiotics, then advertise them as a probiotic drink.
