17 kcal (71 kJ) per 100 ml · P/F/C 0/0/4.2 g
Serving (bottle, 330 ml) — 56 kcal (235 kJ) · Nutri-Score C
Per 100 ml: sugar: medium saturated fat: low salt: low fiber: low
In moderation. Kombucha sits in the middle of the scale — grade C on the open 2023 Nutri-Score algorithm: fine in a balanced diet, but not a “more is better” drink.
Against
- On the drinks scale anything with calories ranks below water: this has 17 kcal and 3.5 g of sugar per 100 ml, and little protein to offset it (0 g).
A typical serving (bottle, 330 ml) has 56 kcal, 0 g protein, 0 g fat and 14 g carbs. Other amounts in the table.
How we judge this, and the sources
The answer comes from the food's composition, not from opinion: its Nutri-Score grade on the open 2023 algorithm, a traffic light for sugar, salt, saturated fat and fiber per 100 g, and the share of daily reference amounts in a typical serving (for salt, sugar, fiber and vegetables, those of the WHO). It rates the food's nutrient profile; it is not medical advice. Formulas, thresholds and every source are on the methodology page; last checked against the sources on November 1, 2026. The short food description was written by our language model (AI) — how we check the text.
