Coffee Soda Recipe

This Sparkling Cold Brew Is the Most Refreshing Way to Enjoy Coffee in the Summer

Coffee soda, fizzy coffee, coffee spritzer, sparkling cold brew — whatever you want to call it, mixing carbonated water with iced coffee is my favourite way to start a warm Summer morning. I've tried a few variations, including the espresso tonic (a little too sweet for my taste) and using coconut La Croix or coconut cold brew for tropical twist, but I'm going to share my go-to three-ingredient recipe for sparkling cold brew.

Feel free to try it with espresso (best if it's room temperature or it melts the ice), regular iced coffee, tonic if you like it sweeter, a twist of lemon or ginger beer to mix things up, or even a splash of your milk of choice if you want something similar to an egg cream.

Here's the world's easiest fancy coffee drink!
