If you’ve ever tried an espresso tonic, you’ll love this soon-to-be summer fad—fizzy cold brewed coffee! It’s a simple, super refreshing carbonated coffee that tastes like a bubbly burst of caffeinated sunshine in a glass.

Your New Summer Sipper

On a warm summer day, there’s nothing better than preparing a refreshing glass of iced coffee… or is there? Spoiler alert: There IS. It’s called fizzy cold brewed coffee, and it’s the best coffee drink you’ll ever have. You can quote me on that one.

This chilled beverage is made using normal cold brew coffee ingredients with the addition of sparkling water. The water gives it a carbonation that provides a perfect bubbly kick. Combined with a strong, familiar coffee flavor, it’s totally unbeatable.

Fizzy cold brewed coffee is especially perfect for long summer afternoons when you need a pick-me-up to avoid a mid-afternoon nap. We’ll make a batch of coffee concentrate and then mix that with sparkling water. BOOM, carbonated coffee, done! Summer, we’re ready for you.

Grab These Ingredients

Fizzy cold brewed coffee requires just three main ingredients. For serving, we can get a little more creative to make this the best coffee drink ever.

Ground Coffee: We’ll use 1 cup of coarsely ground coffee for this recipe.
Cold Water: The coffee will be mixed with 1 ½ cups of water to form the cold brew concentrate, giving you the best coffee-to-water ratio.
Sparkling Water: For fizzy-ness, we will use 2-3 cups of sparkling water.
To Serve: Add whatever you’d like! I suggest using ice cream, simple syrup, and a squeeze of lemon for a refreshingly delicious fizzy drink.

Making This Fizzy Brew Is So Simple

Fizzy cold brewed coffee is made in four simple steps. After letting the coffee steep, the rest of the recipe will take less than 5 minutes.

Step 1: Steep The Coffee
In a large pitcher or bowl, combine the ground coffee and water. Cover and let sit in the fridge for 12 to 24 hours.

Cold Brew Vs Espresso

Cold brew may sound like it’s essentially a cup of espresso, but it’s actually pretty different! Espresso is heated (much like regular drip coffee). Cold brew is never heated and is steeped instead, giving it a smoother, more mellow flavor.

Making cold brew coffee in a jar — Make your cold brew as normal (by letting the grounds steep for at least 12 hours).

Step 2: Strain The Coffee
To separate the grounds, strain the coffee concentrate through a towel-lined fine-mesh sieve (or a French press).

Straining cold brew coffee — Measure your coffee concentrate and add water as needed to reach 1 cup, drizzling the water through the grinds to get as much coffee as possible.

Step 3: Add Some Optional Flavor
This drink tastes best with a touch of simple syrup and/or lemon to counteract the bitterness of the carbonation. To make simple syrup, combine 1 part sugar and 1 part water until dissolved, then add it to your preferred sweetness.

Step 4: Make It Fizzy
Finally, add ice to the glass, then fill it ⅓ full with coffee concentrate. Top it off with carbonated water, optionally adding a splash of creamer!

Recipe Tips

Find the steeping sweet spot
You need to steep coffee for 12-24 hours to get the most flavor from your beans. But, any more than 24 hours will result in a very bitter coffee that won’t taste ideal, even with added flavorings. 12 hours is the sweet spot! I like to let mine steep overnight to be ready for drinking the next morning.

Use the best beans
Arabica coffee beans are the most delicious type of coffee bean for cold brew.

Add milk your brew
Just as you can add cream for flavor, feel free to add milk if that’s what you usually use in your coffee. Dairy, oat, soy, or almond milk will all work, too!
