Add vanilla extract, then fill remaining space in glass with sparkling water.
Stir well, then serve immediately. Enjoy!
Notes
You can make this drink with any kind of plain, unsweetened coffee you'd like, such as cold coffee (from a can or brewed at home), espresso, or cold brew. I prefer to use this easy-to-find cold brew concentrate.Use your favorite sparkling water, such as club soda, mineral water, soda water, or tonic water. I like to use Topo Chico.Check out the info before this recipe card for helpful tips, recipe variations, and more iced coffee ideas!
