Every water ranked by pH

pH measures how acidic or alkaline a water is, with 7 as neutral. It is the number behind the whole alkaline-water category, so this table ranks the most alkaline first. Still mineral waters mostly sit between 6.5 and 8; naturally sparkling waters run more acidic, because dissolved CO₂ turns to carbonic acid and pulls the reading down toward 5.

On its own, pH says little about how a water tastes or what is dissolved in it. A high number usually reflects bicarbonate-rich geology rather than any property of the water itself. Only waters with a sourced pH appear here; absence means not published, never neutral.
