Essentuki No. 17
Essentuki No. 17 from Essentuki, Caucasian Mineral Waters, Stavropol Krai — a label mineralisation of 10 000–14 000 mg per litre. Hardness, what a litre contributes against the EFSA reference intakes, and the EU label claims the analysis supports.
Where it comes from
No. 17 comes from the same field as No. 4 but from deeper and saltier horizons, and its labelled mineralisation of 10 to 14 g per litre places it in the medicinal class rather than the medicinal-table one. That is a legal and practical distinction, not a marketing one: a water at this concentration is not something to keep in the fridge for the family. The taste is strongly saline and alkaline, and the bottle is normally sold with an explicit course of use rather than as a drink.

This is a reference table, not a diagnosis and not a prescription. If a clinician has put you on a sodium, calcium, potassium or fluid restriction, that number comes from them and overrides anything here. Analyses are revised as sources are re-tested, so the label on the bottle you are holding always outranks this page.
The published analysis
| Constituent | mg per litre | What a litre of it means |
|---|---|---|
| Dry residue at 180 °C | 10 000–14 000 | the figure EU law uses for the mineral-content claims |
What EU labelling law lets this water claim
Annex III of Directive 2009/54/EC fixes exactly which indications a natural mineral water may print and the figure each one requires. Applying those rules to the analysis above:
| Indication | Criterion | This water |
|---|---|---|
| “Very low mineral content” | not above 50 mg/l dry residue | does not qualify |
| “Low mineral content” | not above 500 mg/l dry residue | does not qualify |
| “Rich in mineral salts” | above 1 500 mg/l dry residue | qualifies |
| “Contains bicarbonate” | above 600 mg/l bicarbonate | no published figure |
| “Contains sulphate” | above 200 mg/l sulphate | no published figure |
| “Contains chloride” | above 200 mg/l chloride | no published figure |
| “Contains calcium” | above 150 mg/l calcium | no published figure |
| “Contains magnesium” | above 50 mg/l magnesium | no published figure |
| “Contains fluoride” | above 1 mg/l fluoride | no published figure |
| “Contains sodium” | above 200 mg/l sodium | no published figure |
| “Suitable for a low-sodium diet” | below 20 mg/l sodium | no published figure |
