Every bottle, decoded.
55 waters, one standard: mineral profiles, TDS, pH, packaging, and price per liter — plus a disclosure grade, because many brands won’t show their numbers. Independent; we sell nothing on this page.

Values are label- or report-derived reference data (mg/L), stored as midpoints where the source publishes ranges. “—” means the brand does not disclose that value.
On grades & the numbers you see: a disclosure grade reflects what a brand officially publishes, not whether numbers exist. Some C- and D-grade waters still show values drawn from ingredient lists or independent third-party analyses — hover a grade to see that water’s source. See how grades are assigned in our methodology.
On type:we classify each water by its chemistry and treatment, not solely by the marketing name. When a label term (e.g. “spring”) and the measured profile disagree, we type it by the profile and preserve the label wording on the detail page.
