Seltzer is carbonated water with no added minerals, while club soda has added minerals and sparkling water is a broad term for water with bubbles. For most drinks, choose seltzer for a clean taste or club soda for a more mineral-like note.
The terms can overlap on cans and menus, but they don't always mean the same thing. The main difference is whether minerals are present and whether the water started out naturally carbonated.
If you're comparing bottles at the store, read the ingredient list. If you want to make fizzy water at home, start with plain water and decide whether to add flavor after carbonation.
Seltzer vs club soda: what is the difference?
Seltzer is water carbonated with carbon dioxide, while club soda is carbonated water with added minerals. Those minerals can affect taste, so club soda may come across as slightly more mineral-like.
Seltzer usually keeps the flavor of plain water with bubbles. Club soda's mineral additions vary by brand, so one bottle may taste different from another.
Neither is automatically sweetened. Plain versions of both are generally chosen for their fizz rather than fruit flavor or sugar.
What does sparkling water mean?
Sparkling water is an umbrella term for water with carbonation. It can mean water carbonated at a source, water with carbon dioxide added, or a flavored product, depending on the label and brand.
That makes the term less precise than seltzer or club soda. Check the ingredients for added minerals, sweeteners or flavor if you're trying to match a specific drink.
Some sparkling mineral waters have naturally occurring minerals. That's different from club soda, where minerals are added to carbonated water.
Is soda water the same as seltzer?
Soda water is often used to mean carbonated water, but the exact meaning can vary. In recipes and everyday conversation, it may refer to seltzer or club soda.
If a recipe depends on a particular taste, choose a bottle that names the style clearly. For simple hydration, the difference is usually less important than whether you enjoy the flavor.
Which should you use in a drink?
Use seltzer when you want bubbles without a mineral note, and club soda when its added minerals suit the drink. For many recipes, either can work as a fizzy mixer.
Seltzer's plain taste fits fruit, juice and syrups when you don't want the water itself to add much flavor. Club soda can pair well with spirits or citrus when you like a more mineral-like finish.
Try small pours before making a full pitcher. Carbonation level and the other ingredients can change how noticeable the difference feels.
Which is better for cocktails?
Choose by the flavor you want, rather than assuming one is the standard choice for every cocktail. Neutral seltzer keeps the mixer simple, while club soda can add a mineral edge.
For a drink with delicate flavors, start with seltzer so the mixer stays in the background. For a drink with citrus or stronger flavors, try club soda and see whether its taste fits.
Use cold water and add it near the end. Stir gently to keep more of the bubbles in the glass.
Can you swap one for the other?
You can usually substitute seltzer for club soda, or the reverse, in a drink. The main change is taste, since seltzer doesn't bring the added minerals found in club soda.
Start with the recipe's amount, taste, then adjust. If the drink tastes too plain, a splash of citrus or a small amount of syrup can help, depending on the recipe.
Does sparkling water have minerals?
Some sparkling waters contain minerals and some don't. Carbonation by itself doesn't tell you whether minerals were added or naturally present.
Check the ingredients when you're buying sparkling water for a recipe or a particular taste. Terms such as mineral water, seltzer and club soda can point to different ingredients, but brands may use them in different ways.
If you're making your own, a machine carbonates water. It doesn't make plain carbonated water identical to mineral water or club soda.
How can you make seltzer at home?
A soda maker can carbonate plain water at home, giving you a simple base for seltzer-style drinks. Chill the water first and follow the machine's instructions.
The SodaStream Terra Starter Kit includes a reusable bottle and a Quick Connect CO2 cylinder. It carbonates tap water, which you can drink plain or flavor after fizzing.
For a broader walk-through, see how to make sparkling water at home. If you want a different setup, our guide to soda siphons vs SodaStream machines compares two common ways to carbonate water.
How do you flavor homemade seltzer?
Add flavor after carbonating the water, unless your machine's instructions say otherwise. This lets you start with plain bubbles and adjust each glass to taste.
The Bubly Drops Six-Flavor Variety Pack includes strawberry, grapefruit, blackberry, lime, mango and cherry flavors. The drops have no calories or sweeteners.
A squeeze of citrus is another simple option. For more ideas, read how to make sparkling water taste better.
What should you know about CO2 refills?
A soda maker depends on a compatible CO2 cylinder, so check the connection type before choosing a refill. Cylinder capacity and exchange options also affect how you plan to keep making sparkling water.
The SodaStream CO2 Refill, 2 Pink Quick Connect is a two-cylinder pack for compatible machines, including Terra. Each cylinder makes up to 60 liters, and the pack includes an exchange box.
See how to make soda water with or without a machine for other home carbonation approaches. Follow your machine's manual when installing or exchanging a cylinder.
Which one should you choose?
Pick seltzer for a clean, plain mixer, club soda for added minerals, and sparkling water when the label or source tells you what kind it is. For home use, carbonated tap water is a flexible starting point.
If the drink's taste matters, try a small pour of each style before settling on a recipe. If convenience matters more, compare carbonated water makers and choose a machine that fits your counter and refill preferences.

Frequently asked questions
Is seltzer the same as sparkling water?
Seltzer is a type of sparkling water: plain water with carbon dioxide added. The term sparkling water can also describe naturally carbonated mineral water or water carbonated with added minerals, so check the ingredients if mineral content matters to you.
Is club soda better than seltzer for cocktails?
Neither is always better. Club soda's added minerals can give a drink a more mineral-like taste, while seltzer has a cleaner, plainer profile.
Try the same cocktail with both and choose the one that fits its other flavors.
Can I use sparkling water instead of club soda?
Usually, yes, but the taste may change. Plain sparkling water or seltzer can replace club soda in many drinks, though it won't add the minerals associated with club soda.
Start with the same amount and adjust to your preference.
Can a soda maker make club soda?
A home soda maker carbonates water, but carbonation alone doesn't add club soda's minerals. Follow the machine's manual and carbonate plain water first; if you want to add minerals or flavor, check the product directions and use a suitable recipe.
