The short answer
Health Canada says fermented non-alcoholic beverages such as kombucha, kefir and some soft drinks like ginger beer can contain low levels of ethanol, and that although these products are not made to be alcoholic, their ethanol content can vary.
The Public Health Agency of Canada recommends not consuming alcohol during pregnancy or when planning a pregnancy. Health Canada's own instruction for anyone with questions about the ethanol content of these drinks is to speak to a health care provider, which is a fair signal that this is not a question a label settles.
Why there is no single number
Fermentation is the process that turns sugars into ethanol, and it does not politely stop when the bottle is capped. Health Canada says ethanol content varies depending on the fermentation process and on distribution and storage conditions.
That second half is the part worth sitting with. It means the alcohol content of a specific bottle is not fixed at the factory. A bottle that spent a warm week in a van and a fortnight on an unrefrigerated shelf is not in the same state as one that went straight into a chiller, even if the labels are identical.
What the non-alcoholic label actually means
In Canada, the Food and Drug Regulations require beverages containing 1.1% ABV or more to declare the alcohol content on the label. So non-alcoholic here is a regulatory threshold, not a statement that a drink contains none.
This matters because the word carries a promise in everyday speech that it does not carry in labelling. Someone avoiding alcohol completely, which is what the guidance advises in pregnancy, is reading the label as zero when it means below a threshold that can drift.
Provinces and territories oversee control, distribution and sale of alcoholic beverages in their own jurisdictions and may add requirements, and other countries set their own rules, so check the regulations where you live rather than assuming this number travels.
The one practical step Health Canada gives
If you do buy non-alcoholic fermented beverages, Health Canada advises refrigerating them, which limits the fermentation process, and discarding those past their best-before date.
That is unusually concrete for this kind of guidance, and it follows directly from the mechanism: cold slows fermentation, so cold storage limits how much further ethanol develops. It is the same logic as the storage rules on cooked rice, where what happens after the food leaves the kitchen decides the answer.
Health Canada also suggests contacting manufacturers or sellers directly with questions about the ethanol content of specific products and their practices for reducing ethanol formation. For a brand you drink often, that is a reasonable email to send.
Where the alcohol guidance itself sits
The reason a small and variable amount gets treated seriously is that the guidance on alcohol in pregnancy does not work in thresholds. ACOG and CDC both advise avoiding alcohol during pregnancy rather than limiting it, and describe no known safe amount.
That is a different shape of advice from the limits you see elsewhere on this site. Caffeine has a daily number and fish has a weekly one. Alcohol does not, which is why an uncertain trace in a fermented drink turns into a real question rather than a rounding error.
If you already drank some
This page cannot tell you what a specific bottle contained, and nobody can reconstruct it afterwards. What is worth knowing is that this is not a foodborne-illness question, so there is no incubation window to watch and no symptoms to monitor in the way there are after cold deli meat or a runny egg.
The useful response is forward-looking. Note what you drank and how often, and raise it at your next appointment if it has been a regular habit rather than a one-off. A clinician can give you an answer for your own pregnancy, which this page deliberately will not.
Keep the brand and the habit, not just the day
For anything measured as a pattern rather than a single exposure, what your care team needs is roughly how much and how often. Nouri can hold that alongside the rest of your day so the answer does not depend on recall.
Common questions
Can you drink kombucha while pregnant?
Health Canada notes that fermented non-alcoholic beverages such as kombucha, kefir and some soft drinks like ginger beer can contain low levels of ethanol, and that the amount varies. The Public Health Agency of Canada recommends not consuming alcohol during pregnancy or when planning a pregnancy. Health Canada's own advice is to speak to your health care provider if you have questions about the ethanol content of these drinks.
How much alcohol is actually in kombucha?
There is no single number, and that is the point. Health Canada says the ethanol content varies depending on the fermentation process and on distribution and storage conditions. A bottle's content is not fixed at the moment it leaves the factory.
Does a non-alcoholic label mean there is no alcohol?
No. In Canada, the Food and Drug Regulations require beverages containing 1.1% ABV or more to declare the alcohol content on the label. That makes non-alcoholic a labelling threshold rather than a statement that the drink contains none.
Does refrigerating kombucha make a difference?
Health Canada's practical advice for limiting ethanol intake is to refrigerate non-alcoholic fermented beverages, which limits the fermentation process, and to discard those past their best-before date. A warm bottle kept a long time is the situation to avoid.
What about home-brewed kombucha?
Home brewing has none of the controls that commercial production has over fermentation time and temperature, and no labelling requirement at all, so there is no way to know the ethanol content. If you want a specific answer for your own pregnancy, that is a question for your care team rather than one this page can settle.
