The short answer
Think of this as a U.S. regulatory-label guide only — not a worldwide dictionary, and not a four-way recipe chart. FDA material treats sparkling bottled water as separate from added-carbonation beverages such as seltzer, club soda and tonic water. For the specific product in front of you, though, the label itself remains the check that matters.
FDA material groups sparkling bottled water separately from added-carbonation beverages.
Seltzer, club soda and tonic names do not supply one ingredient formula.
Read ingredients, nutrition facts and serving size on the product you choose.

Why this guide is limited to U.S. labels
The U.S. Food and Drug Administration places sparkling bottled water within its bottled-water categories. Water with added carbonation, soda water (including club soda), tonic water and seltzer, it says, have historically been regulated instead as soft drinks.
That classification only describes how the FDA labels these categories within the United States. Other countries are not bound to the same words, and no single brand recipe is implied by any category name.
How the FDA grouping works
| Name on the package | FDA grouping described in the cited guidance | What this guide does not claim |
|---|---|---|
| Sparkling bottled water | Listed in FDA bottled-water categories | One source, mineral or flavour formula |
| Seltzer | Historically treated as a soft drink when carbonation is added | One ingredient formula |
| Club soda / soda water | Historically treated as a soft drink when carbonation is added | One ingredient formula |
| Tonic water | Historically treated as a soft drink when carbonation is added | One ingredient formula |
The table is intentionally regulatory rather than a product recipe chart. Read the actual package for ingredients and nutrition facts.
Use the group, then read the packet
- Start with the name — it tells you which FDA grouping this guide discusses.
- From there, read the ingredients and nutrition facts, using the serving basis shown on that particular product.
- Beyond that, keep the scope clear: this guide does not infer a formula, a nutrition result, or a health effect from a category name.
Practical takeaway: When you are choosing one specific drink, the product label tells you more than a regulatory group can.
Go deeper: regulatory labels and product labels answer different questions
What can the FDA grouping tell you?
It tells you how the cited U.S. FDA guidance describes broad beverage categories. It does not supply the ingredient list, nutrition panel or taste of a particular bottle. Use regulatory context to understand the name, then use that product’s label to understand the product.
Frequently asked questions
Is tonic water the same as sparkling water?
No. The cited U.S. FDA materials place the names in different regulatory groupings. This guide does not infer the ingredients of a particular tonic or sparkling-water product.
Does club soda always have the same mineral content?
This guide does not assign a universal formula. Compare the ingredient and nutrition panels of the products in front of you.
Which one is healthier?
This is not a health, hydration or calorie-ranking article. Use verified product-label information for the product you choose.
