This carbonated version of your beloved coffee has taken the world by storm.

In this article, it’s time to explore what exactly coffee soda is and how to make it at home so that you can become an expert barista too!

Let’s start with an overview to ensure you know everything there’s to know about this drink. Grab a cup of joe and read on because coffee soda awaits!

What is coffee soda?

Coffee soda is a unique and refreshing beverage that combines the flavor of coffee with refreshing sparkling water or your favorite soda water. You can make it with cold brew coffee, iced coffee, or cooled espresso.

Coffee soda has become increasingly popular among people who don’t want to choose between their favorite caffeinated drinks.

The rich, smooth taste of the coffee, combined with the bold sweetness and fizziness from the carbonation, creates an enjoyable experience for all types of drinkers.

You might even consider it to be more flavorful than regular iced coffee!

What does coffee soda taste like?

The taste of coffee soda depends on the specific ingredients used to create it; for example, if you use an espresso roast or cold brew concentrate, the drink will be more intense with a higher caffeine content.

The flavor will be less intense if you use standard drip-brewed coffee to cool it down.

Additionally, you can add coffee syrup, which can alter its overall profile.

Generally, though, it has a strong coffee flavor combined with the sparkling sweetness of your favorite soda water!

And last but not least, you can also use regular brewed coffee to make your coffee soda.

It’s best to let the coffee cool completely before adding it to your sparkling water.

Which soda water is best used?

When it comes to making the perfect coffee soda, you can use many different types of soda water.

It largely depends on personal preference and the flavor profile of the coffee you’re using.

For a refreshing yet balanced taste, sparkling mineral water is usually a great choice since it won’t drown out the flavor of your coffee.

The delicate bubbles and subtle sweetness pair naturally with the coffees listed above.

Another option is club soda if you prefer something lighter in taste; its carbonation will still give off that delicious fizz when blended with coffee.

I prefer using San Pellegrino as I love the more delicate bubbles, but any soda water will work!

How do you sweeten coffee soda?

Coffee soda can be sweetened in various ways to make it more palatable and enjoyable, especially if you’re not a fan of strong coffee.

I suggest using coffee syrup to sweeten your coffee soda, as it will easily dissolve into the drink.
