Freeze Kombucha

Kombucha is amazing warm, cold, and anywhere in between. But what about freezing it? Should you do it? If so, how should you do it and why would you want to?

Let’s dive into those questions!

Can You Freeze Kombucha?

Kombucha can be frozen, however, to preserve the bacteria and yeast culture during freezing, it is crucial to freeze the beverage properly using “fast-freezing.”

If you feel the need to freeze your kombucha, here are some pointers for both store-bought and homemade kombucha.

How Can You Freeze Kombucha?

If you do want to freeze kombucha tea, make sure you “fast freeze” it first. This freezing process will reduce the risk of harming the bacteria and yeast culture in your kombucha when it’s in cold temperatures.

Fill a large bowl with ice and place the packed drink in to chill, then add water as well as a ¼ cup of salt to “fast freeze” something. The salt will cause the water and ice to become extremely cold, chilling the beverage almost instantly.

Once the drink is nice and chilled, put the bottles directly into a freezer that has been set at 0 degrees Fahrenheit (-18 Celsius).

Keep the bottles in the freezer for 24 hours or until they are completely frozen solid before removing them.

It is best to only leave the beverage in long enough to freeze it, as leaving kombucha at low temperatures can slow down its carbonation process. This also can affect how much sugar is converted into alcohol during the fermentation process.

How Should You Store Kombucha In the Freezer?

To maintain the quality of your kombucha, it is important to store it properly in the freezer. Make sure you don’t use plastic bottles or containers when freezing kombucha (really you should never use plastic when dealing with kombucha), as when the drink freezes, it will expand and could cause the plastic to crack.

Use glass bottles or jars with tight-fitting lids when freezing kombucha. Make sure to leave some headspace in the bottles (about an inch or so) as the kombucha will expand when frozen.

How Long Can You Store Kombucha in the Freezer?

You can keep your live drink in the freezer for up to three months. You risk destroying the cultures, probiotics, and germs if you store it for longer than this.

Does Freezing Kombucha Kill The Probiotics?

Probiotics in kombucha are not harmed by freezing kombucha. The probiotics will enter a dormant state as a result of the extreme cold and will reactivate when re-warmed.

However, flash freezing kombucha is the ideal method to preserve the most probiotics.

Slowly freezing the kombucha by placing it in a freezer may damage some of the probiotics but the majority should survive.

Does Kombucha Explode In The Freezer?

The risk of kombucha exploding in the freezer is VERY low. This is because, at colder temperatures, your drink is no longer fermenting and carbonating.

However, it is still possible for bottles to leak or crack if they are not sealed properly or if they are frozen for too long.

To avoid any kombucha mishaps in the freezer, make sure that your bottles are tightly sealed and check on them every once in a while to make sure they are not leaking or cracking.

How Do You Defrost Frozen Kombucha?

When you’re ready to consume kombucha by thawing it, do not leave it out at room temperature or in direct sunlight because this could harm its probiotic culture.

Instead, put the bottles of frozen kombucha directly into your refrigerator for a few hours until they are completely thawed before drinking them.

Defrosted kombucha that has been sitting out for too long can become flat, so it is best to consume it within a day or two of thawing and not leave defrosted kombucha sitting for too long.

Reasons You May Want To Freeze Kombucha

It Could Last Longer

If you live in a hot climate, it might be difficult to stop the Kombucha from continuing to ferment and become vinegar. Although it can technically last indefinitely, it gradually ferments prior to becoming vinegary and unpalatable to drink. As a result, freezing may be a good way to preserve your brew’s flavor. Of course, putting it in the fridge will drastically slow this process down as well.

To Make Kombucha Popsicles

Kombucha may be used to make ice, popsicles, and slushies. It’s fruity, delicious, and sweet, making it a fantastic thirst-quencher on a hot summer day. Simply pour the kombucha into popsicle molds or an ice tray, freeze, and enjoy!

Reasons You Should Not Freeze Kombucha

Freezing Kombucha Can Alter The Taste

Kombucha that has been frozen for a long time (more than a few days will have a much different flavor and texture than fresh kombucha. It may also become excessively carbonated when thawed if enough sugar was used during fermentation.

While freezing does alter the taste of kombucha, many people do successfully freeze their batches for future consumption or to save them from spoiling during periods of high temperature or humidity.

It Could Harm The Bacteria

If you store your kombucha in the freezer for a long period of time, the cell membranes of yeast and beneficial bacteria may rupture as they expand from being kept in the freezer for an extended amount of time.

Furthermore, the ice that can develop during freezing may harm the bacteria.

I don’t recommend freezing kombucha for months at a time because it will lose its flavor and won’t taste as good. If you want to reap the health benefits of kombucha, I would consume it as soon as possible.
