Whether you’re a health lover, a science geek, or just having a discussion with your friends and trying to prove a point, this is the blog for you. If you’ve ever cracked open a can of sparkling water and wondered how the fizz came to be, you’re in the right place. This blog breaks down how water is carbonated (or in simpler words, “where do those bubbles come from?”) and explains the role of pressure, temperature, and more. Let’s dive into how water gets carbonated—spoiler: it’s cooler than you might think.

TYPES OF CARBONATED WATER

Not all bubbles are created equal. Sparkling water isn’t just one thing—there are different types with their own unique vibes. Here’s a quick breakdown:

• Seltzer:

  No minerals, CO₂ added artificially, no additives—just pure fizz.

  
  
  

• Club Soda:

  Minerals and CO₂ added artificially, no additives. Provides a slightly salty kick and is perfect for cocktails or when you want a little extra flavor punch.

  
  
  

• Natural Sparkling Water:

  Contains naturally occurring minerals and CO₂. It’s naturally fizzy from underground springs, with minerals that give it a distinct taste. Think fancy European brands you spot at upscale restaurants.

  
  
  

• Sparkling Water:

  Natural minerals with added CO₂. Often used as a catch all term, sometimes natural, sometimes artificially carbonated.

  
  
  

• Tonic Water:

  Added CO₂ and quinine. Fizzy, bitter, and slightly sweet—gin and tonic fans, this one’s for you.

Fun fact: The type of carbonated water you choose can totally change the flavor of your drink. So next time you grab a bottle, you’ll know what you’re sipping. Discover why does spakling water taste different. 

NATURAL vs. ARTIFICIAL CARBONATION

Both methods get you that satisfying fizz—but natural carbonation brings in those extra mineral flavors, while artificial carbonation gives brands the power to control the bubble level. Here’s an overview:

• Natural carbonation

  happens when water passes through mineral-rich rocks underground, picking up CO₂ along the way. The result? Naturally fizzy water with a mineral-forward taste.

  
  
  

• Artificial carbonation

  is where science steps in. CO₂ gas is added to still water under pressure to create those crave-worthy bubbles. This is how most bottled sparkling waters (and your favorite sodas) are made.

HOW IS ARTIFICIAL CARBONATION DONE?

Artificial carbonation isn’t just someone blowing bubbles into a bottle (though that would be fun to watch). It’s a three-step process that’s all about science and precision:

1. Chill the Water:

   Cold water holds CO₂ better. That’s why manufacturers cool it down to near-freezing temps before adding gas.

   
   
   

2. Add the CO₂:

   Under high pressure, CO₂ is pumped into the chilled water. This creates carbonic acid, which gives sparkling water that signature tang.

   
   
   

3. Seal the Deal:

   The carbonated water is bottled under pressure to lock in the bubbles. Pop the cap, and—hello, fizz!

   
   
   

Instead of bottling, we offer the REFILL+ system—a single-plastic-free solution that delivers fresh, carbonated water with added flavors and vitamins. It's designed for offices and hotels, allowing users to enjoy the fizz without the waste.
