How to Make Espresso Tonic

Even though it only has two ingredients, there are a few things to note before you make your own. Some cafés offer twists on the espresso tonic by serving it with a flavored syrup. Starbucks even has recipes featuring orange and crushed cardamom. One of my favorite ways to enjoy it is by making a cold brew tonic with a bit of simple syrup, a twist of lemon or lime, and a sprig of fresh mint. It’s the perfect refreshing summer drink on a hot day.
