Short answer: at one point in its life, yes, kombucha is alcoholic. By the time it reaches your can, ours isn’t. If you want the honest version of how that works, and most brands would rather you didn’t ask, pull up a chair.
Does kombucha have alcohol in it?
Kombucha starts as sweet tea. Add a culture of yeast and bacteria, and the yeast does what yeast always does: it eats the sugar and gives off two things, carbon dioxide and alcohol. That’s the natural fizz, and it’s the same process that makes beer. In the early stages of fermentation a strong kombucha can climb to 3 to 4% alcohol. So anyone who tells you kombucha has never been near alcohol is quietly skipping a chapter.
Is kombucha alcohol, then, or is kombucha tea?
Both, at different points. Kombucha is fermented tea, and fermentation is what makes alcohol in the first place, so for a stretch in the middle of the process, kombucha genuinely is an alcoholic drink. What makes it kombucha tea rather than kombucha beer is what happens next: a second set of bacteria goes to work and brings that alcohol back down. Call it kombucha tea once that second stage has finished the job.
How much alcohol is in kombucha, then?
It depends entirely on who made it and how far they took it. Left alone, kombucha keeps that alcohol. The clever bit, the thing that separates a stable drink from a science experiment, is what happens next.
How we take the alcohol back out
There are two crews in a kombucha culture. The yeast makes the alcohol. The other lot, the Acetobacter (acetic acid bacteria), eat that alcohol and turn it into acetic acid, which is what gives kombucha its clean, tangy bite. Most of the balance in the glass comes from letting those two finish their jobs.
So we don’t rush it. We extend our fermentation to give the acetobacter time to metabolise the alcohol the yeast made, the same way the culture would if you left it long enough in nature. We ferment a strong base, then blend it back with more tea and our hops to balance the flavour and keep every batch naturally stable and consistent. By the end of the process, the alcohol has dropped below detectable levels.
So is the kombucha in my hand alcoholic?
Ours, no. It has been through the full process, so what you are drinking is a naturally fermented, effectively alcohol-free real kombucha. No shortcuts, no chemistry set, nothing added to fake the balance. Just time, tea and hops doing the work. Same story with the caffeine, by the way: a little, not a lot.
What about homemade kombucha?
Home-brewed kombucha can be a different story, and it is worth knowing why. A home batch is usually a single, shorter ferment. The yeast still makes its alcohol, but the brew often gets bottled before the acetobacter have had the time to work through it, and there is no post-ferment blending to even things out. Without that extra time, more of the alcohol simply stays in. A strong home brew can sit above the 0.5% line, sometimes a fair bit higher.
None of that is a knock on home brewing. It is how kombucha has been made for centuries. Just know that a jar on the kitchen counter and a finished, stable can are not always the same drink when it comes to alcohol.
The common-sense version
Kombucha is fermented tea. Fermentation makes a little alcohol, and a good process turns it back into flavour. That is it. No mystery, nothing to hide, and nothing on the back of the can we would need to explain to you.
Some people call that health and wellness. We call it common sense.
Questions we actually get asked
Is kombucha alcohol?
For a stretch during fermentation, yes, kombucha genuinely is alcoholic. A second stage of fermentation brings that alcohol back down, and by the time Life Blood reaches a can, it is below detectable levels.
Is kombucha tea the same as alcoholic kombucha?
No. "Kombucha tea" usually means the finished, low-and-no drink most people buy. Alcoholic kombucha is a different, deliberately unfinished product, sometimes sold separately with an ABV on the label.
Can kids or pregnant women drink kombucha?
Life Blood is brewed to sit below detectable alcohol levels, but if you are pregnant, breastfeeding, or buying for a child, it is always worth checking the label and, if in doubt, speaking to a doctor or midwife.
Why does kombucha have alcohol in the first place?
Because it is fermented, and fermentation is yeast eating sugar and producing alcohol and carbon dioxide. That is the same basic process that makes beer, wine and cider.
