What exactly is Kombucha?

If you’re new to the kombucha world, you’re undoubtedly wondering, “What exactly is kombucha?”

Kombucha, or “Booch,” is a sweetened black or green tea with bacteria and yeasts added to kickstart fermentation.

The notion that kombucha is secretly alcoholic has been flying around for a long time, however the amount of alcohol produced by fermentation is minimal. The alcoholic content of kombucha is roughly equivalent to that of a glass of juice.

How Long Will Kombucha Keep?

Temperature of Storage

Kombucha, being the fantastic, naturally fermented beverage that it is, can keep for an exceptionally long period. There are several elements that influence how long your kombucha will last. Does Kombucha Expire or Go Bad These are some examples.

Kombucha should be kept cool, ideally refrigerated. When kombucha is stored in this manner, fermentation comes to a halt, giving you much more time to enjoy your kombucha at its best.

Containers that are properly sealed

Another disadvantage of kombucha is an inadequately sealed container. Kombucha should be stored in an airtight bottle, which means nothing can get in or out until the bottle is opened for consumption.

Duration of Time

Why Is There an Expiration Date on Kombucha?

You might be shocked to find that federal law does not require an expiration date for most foods.

Infant formula and baby meals are the only foods that must have expiration dates. Does Kombucha Expire or Go Bad Milk, eggs, and meat are occasionally regulated by state legislation and must consequently have expiration dates.

How Long Does Opened Kombucha Keep?

In contrast to kombucha that is still sealed in its airtight bottle, unsealed kombucha can and will deteriorate. Once the kombucha has been opened, it must be refrigerated. Does Kombucha Expire or Go Bad Refrigerated opened kombucha will keep for around a week.

Spoiled kombucha is unsafe to consume. Does Kombucha Expire or Go Bad It’s impossible to know what kinds of bacteria and molds have made their way into your kombucha.

If your drink smells bad or is discolored, throw it out. It is not worth the risk of becoming ill in order to taste test it.

Homebrewed Kombucha vs. Commercial Kombucha

Another issue to consider when it comes to kombucha expiry is where it came from.

Kombucha that has been professionally made with good quality control will, on average, last longer. Does Kombucha Expire or Go Bad Because these kombuchas are equally packaged and sealed, there is less room for error.

This isn’t to suggest that homemade kombucha isn’t delicious on its own! Just be mindful of how old this kombucha is, and avoid drinking anything that smells or tastes weird to you.


Kombucha is incredible! It’s naturally carbonated, packed with probiotics, and has been shown to help with digestion.
