Can you freeze Kombucha?

While it is possible to freeze kombucha, you should be mindful of the potential impact on the beneficial bacteria and yeast cultures present in the drink. Freezing kombucha extremely cold, could compromise its probiotic content, as extreme cold temperatures can harm the living organisms responsible for its health benefits.

What happens if a SCOBY freezes?

A kombucha SCOBY (Symbiotic Culture of Bacteria and Yeast) is a crucial component in the kombucha-making process. If exposed to freezing temperatures, the delicate balance of bacteria and yeast cultures may be disrupted, which could hinder its effectiveness in future kombucha batches.

Freezing probiotic beverages

When considering freezing probiotic beverages like kombucha, it’s essential to understand the potential loss of beneficial bacteria and yeast culture due to cold temperatures. Instead of freezing, explore other preservation methods, such as refrigeration, to maintain the probiotic culture content and health benefits of kombucha.

Preserving kombucha SCOBY

To store a kombucha SCOBY when not in use, place it in a glass container with a small amount of kombucha liquid and store it in a cool, dark location like a pantry or cupboard. Properly cared for, a SCOBY can last for several months or even up to a year. Freezing a kombucha tea or SCOBY may cause harm, so avoid this method for storage.

Frozen Kombucha popsicles and slushies

If you’re interested in making kombucha popsicles or kombucha slushies yourself, you can freeze your kombucha. However, be aware that this might reduce the probiotic content. Pour the kombucha into popsicle molds for frozen treats or partially freeze and blend with frozen fruit for a refreshing slushie.

Safety measures when freezing kombucha

Before freezing your homemade kombucha, consider the following safety precautions:

  • Use suitable containers: Avoid glass bottles, as the expanding liquid can cause them to break. Use plastic or freezer-safe glass containers instead.
  • Leave room for expansion: Allow for headspace in the container to accommodate the expanding liquid as it freezes.
  • Monitor carbonation levels: Open containers slowly after thawing to prevent pressure buildup, which could cause an explosion.

Alternative methods for preserving kombucha

If you’re hesitant to freeze your bottle of kombucha?, there are other ways to preserve it and extend its shelf life.

  • Refrigeration: Storing kombucha in the refrigerator can slow down the fermentation process, helping maintain its taste and probiotic content for a more extended period. Keep the kombucha in airtight bottles to maintain carbonation levels.
  • Canning: Although less common, some people choose to can their kombucha to preserve it. This method involves heat pasteurization, which can kill off some of the beneficial bacteria and yeast. However, it allows you to store kombucha at room temperature for an extended period.

Can You Freeze Kombucha FAQ’s

Will probiotics endure freezing?

No most probiotics will not endure freezing. The survival of probiotics during freezing depends on various factors. While some strains of beneficial bacteria may survive, others might not.

Can freezing a SCOBY be harmful?

Freezing a SCOBY can potentially damage or kill it, so it’s best to avoid freezing it for storage purposes.

Will kombucha continue to ferment if frozen?

Frozen kombucha will not continue to ferment, as the low temperatures slowly freezing will halt the fermentation process.


In conclusion, while you can indeed want to freeze kombucha yourself, freezing kombucha directly may affect the live probiotics present in the drink, reducing its health benefits. However, if you’re more interested in the taste and texture of frozen kombucha in the form of popsicles or slushies, feel free to freeze it and enjoy.

When it comes to storing a SCOBY, it’s best to avoid freezing it, as the cold temperatures can damage the delicate bacteria and yeast cultures. Instead, store the SCOBY in a cool, dark place with a small amount of kombucha liquid.
