What is sparkling mineral water and how is it different from regular water?

Quick answer

Sparkling mineral water is bottled water from a protected source that carries dissolved minerals, with bubbles that are either natural to the spring or added. Regular water has no bubbles, and ordinary sparkling water is usually plain water with carbon dioxide added. Both hydrate you; the real differences are taste, mineral content and price.

What is sparkling mineral water?

Sparkling mineral water is bottled water that comes from a mineral source and keeps its dissolved minerals, such as calcium, magnesium and sodium, and is served fizzy. Mineral water is defined by those minerals, not by the bubbles. One explainer notes that mineral water is generally described as containing at least about 250 parts per million of dissolved minerals and that minerals cannot be added to it. This is general information; rules differ by country, so the label is the final word.

How is it different from regular water?

Regular (still) water, whether from the tap or bottled, has no bubbles and may have few or many minerals depending on the source. Sparkling mineral water has bubbles and a mineral taste that changes from brand to brand, sometimes slightly salty, sometimes soft and round.

Type Bubbles Minerals
Still water None Varies by source
Sparkling (carbonated) water Carbon dioxide added Varies; check the label
Sparkling mineral water Natural or added, check the label Kept from the source

Is the fizz natural?

Sometimes. Some springs are naturally carbonated, and some brands say so on the label. Others add carbon dioxide to mineral water before bottling. Phrases such as naturally sparkling versus carbonated tell you which. Do not assume.

Is it healthier or more hydrating?

Both still and sparkling water count toward your fluids, and plain sparkling water has no sugar or calories, which is why people swap it for soda. The minerals in mineral water add taste, and the amounts vary by brand. The label lists them per liter if you want to compare, but no one bottle is a cure or a fix for anything.

How to choose

  • For everyday drinking: plain still or sparkling water is fine and usually cheaper.
  • For taste: try a mineral water with a lower mineral total if you find strong mineral flavor harsh, or a higher one if you like it.
  • For mixing: pick a neutral, fine-bubble water so it does not fight the other flavors.
  • Watch for: flavored versions with added sugar or sweeteners, and sodium on the label if you limit salt.

Serving tips

Serve it cold; fizz lasts longer in a chilled bottle. Reseal tightly after opening, and drink within a day or so for the best bubbles. A slice of lemon or lime is enough flavor for most people.

People also ask

Is sparkling mineral water the same as club soda?

No. Club soda is carbonated water, often with added minerals or salts for taste. Mineral water keeps minerals from its source. Check each label.

Does sparkling mineral water hydrate as well as still water?

Yes, both count as fluids. Choose by taste and any sodium you want to limit.

Is all mineral water naturally carbonated?

No. Some is naturally fizzy, some has carbon dioxide added, and some is still. The label says which.
