Seltzer Water and Sparkling Water

Water is water, right? Not quite. When it comes to the world of carbonated waters, things can get a little fizzy—particularly when trying to distinguish between seltzer water and sparkling water. Both of these bubbly beverages are popular alternatives to still water and sugary sodas, making them a common feature in many homes and restaurants. However, despite their shared effervescence, seltzer water and sparkling water are not the same.

At a glance, seltzer water is pure, carbonated water with no added minerals, while sparkling water can either refer to water that is naturally carbonated from a spring or well and contains minerals, or, in some cases, water that has been artificially carbonated and has had minerals added to it. The key differences between these two fizzy waters lie primarily in their production process and mineral content, which we will delve into throughout this article.

This article aims to provide a clear understanding of what makes seltzer water distinct from sparkling water, debunking misconceptions, and helping you make an informed decision when you reach for your next hydrating, fizzy refreshment. So, let’s dive in!

Understanding Seltzer Water

Seltzer water, commonly referred to as just seltzer, is a type of carbonated water that has its roots in the mid-18th century. The name “seltzer” comes from the renowned natural springs in Selters, a region in Germany known for its mineral-rich waters. However, the seltzer water we know and consume today does not contain these naturally occurring minerals.

Modern seltzer water is simply plain water that has been artificially carbonated. The process involves pressurizing carbon dioxide (CO2) into water at low temperatures, creating the familiar effervescence we associate with this drink. The result is a pure, clear beverage with a refreshing, subtle taste.

Due to its mild flavor and effervescence, seltzer water has found its way into a multitude of culinary applications. It’s a popular mixer for cocktails and non-alcoholic beverages, as it adds fizz without altering the drink’s flavor profile. It’s also commonly used as a leavening agent in baking, providing lightness to dough and batter.

Moreover, seltzer water can be infused with various natural flavors, such as lemon, lime, or berry, offering a more enjoyable drinking experience for those seeking flavor without the added sugars and calories of traditional sodas. From the cocktail bar to the bakery, seltzer water brings versatility, effervescence, and a hint of sophistication.

Understanding Sparkling Water

Sparkling water, also known as carbonated water or fizzy water, has a longer history than its seltzer counterpart. The first record of naturally carbonated water comes from the springs and wells of Europe, where gases from the ground naturally infused with the local groundwater. These fizzy waters were often believed to possess therapeutic properties, and “taking the waters” became a popular health trend.

Sparkling Water

Modern sparkling water can come from two sources. Natural sparkling water is sourced from springs or wells that contain naturally occurring gas and minerals. The carbonation in this water comes from the ground and is present when the water is sourced. On the other hand, some brands of sparkling water are artificially carbonated, similar to seltzer. These often have minerals added to replicate the taste of natural sparkling water. The presence of these minerals gives sparkling water a slightly salty taste and different mouthfeel compared to seltzer water.

Like seltzer water, sparkling water is widely used in the culinary world. It’s a common base for mocktails and cocktails, where its natural minerals can complement other flavors. In cooking, it’s often used in batter for its lightening properties. Chefs also use it to deglaze pans, as the acidity from the minerals can help lift the fond from the bottom of the pan.

Sparkling water can also be flavored with natural essences or extracts, but unlike seltzer, these flavors often have to compete with the existing mineral taste of the water. As a result, flavored sparkling waters often have a more complex taste compared to their seltzer counterparts.

The Key Differences between Seltzer Water and Sparkling Water

While seltzer water and sparkling water may seem nearly identical, especially when bubbles start fizzing, their differences become more evident when we consider their nutritional composition, taste profiles, and health implications.

The Key Differences between Seltzer Water and Sparkling Water

Nutritional Composition

Seltzer water, being nothing more than plain water with added carbon dioxide, has no calories, sodium, or other minerals. It’s essentially just carbonated water, providing hydration with a fizzy twist.

Sparkling water, on the other hand, can vary in its nutritional composition depending on its source. Natural sparkling water contains minerals like calcium, potassium, and magnesium, which it absorbs from the ground. These minerals can contribute to your daily intake, though the amounts are typically quite small. Artificially carbonated sparkling water may also contain added minerals to mimic the taste of natural sparkling water.

Taste Profiles

The taste difference between seltzer and sparkling water mainly stems from their mineral content—or lack thereof. Seltzer water has a clean, neutral flavor because it’s just plain water that’s been carbonated. It can take on added flavors easily, which is why it’s often used as a base for flavored carbonated beverages.

Sparkling water, particularly if it’s naturally sourced, has a distinct taste that can be described as slightly salty or mineral. This taste comes from the minerals naturally present in the water. Some people find this flavor profile more enjoyable and complex compared to seltzer water.

Health Implications

Both seltzer and sparkling water are healthy beverage options, especially if you’re trying to reduce your intake of sugary drinks. They’re calorie-free and provide hydration just like still water. Sparkling water may provide small amounts of minerals, but generally not enough to make a significant impact on your daily nutritional needs.

The carbonation in both drinks can lead to feelings of fullness, which can be helpful if you’re trying to control your appetite. However, it’s worth noting that for some people, carbonated beverages can cause indigestion or heartburn. If you have irritable bowel syndrome or similar digestive conditions, you may want to limit your intake of carbonated drinks. As always, if you have any health concerns, it’s best to consult with a healthcare professional.

Choosing Between Seltzer Water and Sparkling Water

When it comes to deciding between seltzer water and sparkling water, your choice will largely depend on personal preference, dietary needs, and culinary applications.

Choosing Between Seltzer Water and Sparkling Water

Culinary Uses and Beverage Pairing

Seltzer water, with its clean and neutral flavor profile, is ideal for dishes and beverages where you want the bubbles without any additional taste. It’s excellent for making light batters, as a mixer in cocktails and mocktails, or for infusing with various flavors without competing elements. In essence, seltzer water is a blank canvas waiting for your culinary creativity.

Sparkling water, due to its mineral content, imparts a distinct flavor profile that can enhance certain recipes. For instance, it’s great for deglazing pans to make flavorful sauces. When paired with wine or used in cocktails, the minerals in sparkling water can add depth and complexity to your beverage.

Dietary Restrictions and Health Considerations

In terms of health, both seltzer and sparkling water are good options for those who want to stay hydrated while enjoying a fizzy drink. However, they may not be suitable for everyone. For instance, some individuals might find that carbonated beverages cause or worsen digestive issues.

Sparkling water’s mineral content might also be a consideration. For instance, those on a low-sodium diet might want to check the label of sparkling waters, especially those that are naturally sourced, as they can contain small amounts of sodium. Conversely, those looking to boost their intake of minerals like calcium or magnesium might find naturally sourced sparkling water a beneficial addition to their diet.

Ultimately, the best choice between seltzer water and sparkling water depends on your personal taste, dietary needs, and how you plan to use the water. Both offer an appealing alternative to still water and a healthier choice compared to sugary drinks, so you can’t really go wrong!

Common Misconceptions about Seltzer Water and Sparkling Water

When it comes to seltzer and sparkling water, there’s no shortage of misconceptions floating around. Let’s pop a few of these bubbles and clear the air.

Common Misconceptions about Seltzer Water and Sparkling Water

Myth 1: Seltzer Water and Sparkling Water are Bad for Your Bones

There’s a common belief that drinking carbonated beverages can lead to decreased bone health. This misconception likely stems from studies on soft drinks, particularly colas, which have been associated with lower bone mineral density. However, the research points towards the high intake of phosphoric acid present in colas, not the carbonation itself, as the potential issue. Neither seltzer nor sparkling water contains phosphoric acid, making them safe for your bones.

Myth 2: Carbonated Water Can Lead to Weight Gain

Another myth is that carbonated water can contribute to weight gain. This misconception might come from the association between carbonated soft drinks and obesity. However, plain seltzer water and sparkling water without added sugars or sweeteners contain no calories and will not directly lead to weight gain. In fact, because the carbonation can make you feel full, these waters might even help control overeating.

Myth 3: Carbonated Water is Bad for Your Teeth

Some people worry that the carbonation in seltzer and sparkling water can erode tooth enamel. While it’s true that very acidic drinks can harm your teeth, plain seltzer and sparkling water are generally not acidic enough to cause concern. That said, flavored varieties can be more acidic, so it’s a good idea to drink them in moderation and to maintain good oral hygiene.

Myth 4: Carbonated Water Causes Dehydration

Contrary to this belief, carbonated water is just as hydrating as still water. The fizziness might make you feel a bit bloated if you drink large amounts at once, but it does not affect your body’s ability to absorb and use the water.

These myths underscore the importance of looking at science before drawing conclusions about food and drink. Always remember that not all carbonated beverages are created equal, and seltzer water and sparkling water stand apart from sugary, acid-rich sodas.


Deciphering the difference between seltzer water and sparkling water might initially seem like splitting hairs, but as we’ve discovered, there are indeed distinctions between these two fizzy beverages.

Sparkling water, on the other hand, can either be naturally or artificially carbonated and often contains minerals, either naturally occurring or added during production. These minerals give it a distinctive taste and can also slightly contribute to your daily mineral intake.

From a health perspective, both seltzer and sparkling water are excellent, calorie-free alternatives to sugary drinks, offering hydration with a fun, fizzy twist. However, if you have specific dietary needs or restrictions, you may need to consider the mineral content of sparkling water. And as always, if you have any health concerns, consult with a healthcare professional.

In the end, the choice between seltzer water and sparkling water largely comes down to personal preference and intended use. So, whether you’re a seltzer fan or a sparkling water aficionado, keep enjoying these bubbly hydrators and explore their versatility in your culinary adventures. Stay hydrated and keep fizzing!


Q: Which is better, sparkling water or seltzer water?

A: The answer to this question largely depends on your personal preference and dietary needs. Both sparkling water and seltzer water are excellent, healthier alternatives to sugary drinks as they offer hydration without any calories. If you prefer a more complex, mineral taste, you might favor sparkling water. If you’re after a clean, neutral taste, seltzer water might be your pick. In terms of health considerations, both are generally healthy, but you might want to check the mineral content if you’re on a specific diet or have particular health conditions.

Q: Can you substitute sparkling water for seltzer water?

A: Yes, you can substitute sparkling water for seltzer water and vice versa in most cases. The main difference between the two is the taste – sparkling water, especially if naturally sourced, can have a slight mineral taste due to its mineral content, while seltzer water has a more neutral flavor. However, these differences are often subtle and may not significantly affect the outcome in cooking or beverage mixing.

Q: Is sparkling soda and seltzer water the same thing?

A: The term “sparkling soda” can be a bit ambiguous, but it’s typically used to refer to a carbonated beverage with added flavors, and often sweeteners. Seltzer water, on the other hand, is simply carbonated water without any additives, though flavored versions are available. So, while both are carbonated, they aren’t quite the same – seltzer water is generally a simpler, healthier choice, while a sparkling soda might be more similar to a soft drink.
