Kombucha
Kombucha is a fizzy drink made by fermenting sweetened tea with a culture of bacteria and yeasts called a SCOBY. As the sugar is largely used up during fermentation, the finished drink stays light: about 6.61 kcal per 100 g. Tangy and slightly vinegary, it is often used as an alternative to fizzy drinks, with a more complex taste and much less sugar.

Tips
Kombucha is drunk fresh, as an alcohol-free aperitif or with a meal. A 200 ml glass is plenty. It contains traces of alcohol from the fermentation (generally less than 0.5%), so it is not recommended for pregnant women and young children.
- Nutrition: very low in calories, about 6.61 kcal per 100 g, but shop-bought recipes vary a great deal, and some are much sweeter.
- Good to know: check the sugars on the label before you buy. Our guide on hidden sugar explains how to read these labels.
Like kefir or kimchi, kombucha relies on fermentation: our guide to probiotics and the gut microbiome reviews their real effects. Compare its calories with those of other drinks or see the calorie table.
