What is Kombucha?

Kombucha is a fermented tea made by adding a SCOBY (symbiotic culture of bacteria and yeast) to sweetened black or green tea. After 7–14 days of fermentation, you get a naturally carbonated, probiotic-rich drink with a tangy taste and trace amounts of alcohol (usually under 0.5%).

Fermentation is a living process. Yeast in the SCOBY break the sugar down into alcohol and CO₂ — that’s the natural fizz — and bacteria then turn most of that alcohol into organic acids, which give kombucha its tang. Let it run too long and the acids take over, which is why kombucha can taste like vinegar. Some of the tea’s caffeine stays in the finished drink too — here’s how much caffeine is in kombucha. What you end up with is a lightly fizzy drink with live cultures and far less sugar than most sodas.

All you need is a SCOBY, tea, sugar, and a jar. I’ve brewed over 500 batches, and this site walks you through every step — from brewing your first batch and choosing the best tea for kombucha to a second fermentation for more fizz and creating your own flavor combinations.

Curious about the health side? I’m not a doctor, so I stick to what the research actually supports — on kombucha’s real benefits, how much alcohol is really in it, and whether it’s safe during pregnancy.
