This cold brew tonic recipe is easy to make and always so delicious and refreshing.
This seems to be the summer of cold brew tonics here in Europe. ♡
We’ve been seeing them featured on coffee shop menus everywhere we’ve traveled lately. And after sampling a few, I understand the draw — they’re so fizzy and refreshing!
The concept is just as it sounds — cold brew concentrate is served over ice, topped with bubbly tonic water, and garnished with a slice of lemon or orange. We’ve seen various versions made with espresso too, but I have to say that I definitely prefer the smoother, non-acidic flavor of cold brew in this drink. It pairs perfectly with the more bitter, botanical flavor of the tonic water (Fever Tree is my go-to). And when served ice cold with a squeeze of citrus on a hot summer day, this drink is downright delightful.
Here’s how to make one!
Cold Brew Tonic Ingredients
Before we get to the full recipe below, here are a few notes about the four ingredients you will need to make this cold brew tonic recipe:
Cold brew concentrate: Feel free to either make homemade cold brew concentrate (<– here is my tutorial and recipe) or purchase store-bought cold brew concentrate (<– I enjoy this brand). If you’re using store-bought concentrate, please note that brands can vary significantly in terms of how strong their concentrate may be. So I would recommend starting with a bit less concentrate, then give the drink a taste, and you can always add more if you would like.
Citrus: I recommend serving the drink with a squeeze of either fresh orange or lemon, which adds such a lovely hint of citrus to the drink.
Ice: Finally, you will need a glass full of ice to serve this drink.
Here are a few other variations that you’re welcome to try:
Add sweetener: Tonic water already adds significant sweetness to this drink. But if you prefer your coffee even sweeter, you are welcome to stir in some simple syrup or your preferred sweetener.
Add a cherry: For a fun cocktail-y twist, we occasionally love adding a Luxardo cherry to our cold brew tonics.
Use a flavored tonic water: There are all sorts of flavored tonic waters available nowadays that could add some interesting notes to this drink. But please pick wisely…some flavors could also be a bit of a disaster. ;)
Use espresso: You could also swap freshly-brewed espresso for cold brew concentrate if you would like. I would just recommend popping the espresso shots in the freezer for 10 minutes before making the drink so that they do not melt too much of the ice.
