This iced coffee soda is the most refreshing way to caffeinate! Add bubbles to cold brew for uniquely delicious carbonated coffee.

Coffee Soda

Love a good nitro coffee, cold brew, or iced coffee? Then you’ll adore this unique way to caffeinate: the Coffee Soda! Blend equal parts soda water and cold brew coffee for this one, served up in a tall glass with ice. The flavor blew us away: it’s bittersweet and bubbly, with a brightness from the carbonation that’s reminiscent of nitro coffee. This is our new favorite way to drink coffee, especially into the afternoon! It’s essentially homemade nitro coffee and insanely refreshing.

What is coffee soda?

Coffee soda is a drink of espresso or cold brew topped off with club soda. It’s a way to mimic carbonated coffee, without actually carbonating the beverage. The flavor is similar to nitro coffee, though nitro is cold brew coffee infused with nitrogen bubbles. It’s a great way to infuse new life into cold brew, and with no sweetener it’s a very low calorie drink! Here are the ingredients you’ll need for coffee soda:

How to make coffee soda

Coffee soda is as simple as pouring cold brew and club soda in a glass! But here are a few notes:

  • Use equal parts coffee and soda water. This ratio yields the best flavor.
  • Add sweetener if you like. We used 1 teaspoon maple syrup for just a hint of sweet.
  • Step it up with clear ice. Crystal clear ice makes a statement, and is easy to make at home.
  • Top with cold foam. Increase the fun factor with cold foam: frothed milk used for topping iced coffee.
