Frequently Asked Questions About Plain Kombucha
What is plain kombucha?
Plain kombucha is fermented tea made with a culture of bacteria and yeast, often called a SCOBY. It has a tangy, lightly fizzy taste; “plain” means unflavored, not necessarily sugar-free.
Does plain kombucha contain caffeine?
Yes, plain kombucha usually contains some caffeine because it is made from tea. Fermentation does not remove all the caffeine, and the amount varies with the tea and brewing method; people sensitive to caffeine may prefer to avoid it near bedtime.
Is plain kombucha alcoholic?
Yes, fermentation naturally produces some alcohol in plain kombucha. The amount varies with brewing and storage, so it should not automatically be treated as alcohol-free by people who need to avoid alcohol completely.
Is plain kombucha good for gut health?
Plain kombucha may contain live microbes if it has not been pasteurized, but the cultures vary by product. It is not a proven treatment for digestive conditions, and pasteurization can reduce or remove live cultures.
Does plain kombucha have sugar?
Yes, plain kombucha can contain residual sugar because sugar is used during fermentation and may not all be consumed. “Plain” describes the lack of added flavoring, not the absence of sugar; the amount varies by product.
How much plain kombucha should you drink in a day?
There is no established daily amount of plain kombucha that everyone should drink. If you are new to it, try a small serving first, since its acidity, carbonation, caffeine, and residual sugar can bother some people.
Can you drink plain kombucha while pregnant?
It is safer to avoid plain kombucha during pregnancy, particularly homemade or unpasteurized versions, because alcohol content and the risk of unwanted microbes can vary. Ask your healthcare professional for advice specific to your pregnancy.
Does plain kombucha need to be refrigerated?
Yes, refrigerate plain kombucha, especially after opening, unless its packaging gives different instructions. Cold storage slows fermentation but may not stop it completely, so open the bottle carefully if pressure has built up.
Can you make plain kombucha at home?
Yes, plain kombucha can be made at home by fermenting sweetened tea with starter kombucha and a SCOBY. Use clean equipment and discard the batch if you see mold or notice an unusual smell or appearance.
Why is plain kombucha fizzy?
Plain kombucha is often fizzy because yeast produces carbon dioxide as the tea ferments. Some bottled versions may also be carbonated, so the amount of fizz can differ from one product to another.

What is Plain Kombucha?
Plain Kombucha is a lightly sparkling drink made by fermenting sweetened tea with a culture of bacteria and yeast. Its roots are commonly traced to East Asia. Fermentation gives it a gently tart, tea-like flavour and fine bubbles; the sweetness and acidity vary with the brew.
It is usually served chilled, either on its own or alongside a meal, and can suit anyone looking for a tangy alternative to soda. It is mostly water and relatively low in energy, with 16 calories per 100 g. Try a small glass first if you are new to its sharp flavour, and check the label if you are keeping an eye on sugar, since amounts can vary between products.
