Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Kombucha contains small amounts of alcohol produced during fermentation?

Yes. Multiple sources state that kombucha contains alcohol produced during fermentation: a yeast-spectrum reference says the beverage contains small amounts of alcohol, a chemistry-education paper reports detectable ethyl alcohol (under 0.5% to be nonalcoholic), and a study measured 0.20% alcohol in a blueberry kombucha.
