How to Make Cold Brew Ice Cubes

Words Erin Meister

Why worry about watering down your iced coffee with regular (read: boring) ice cubes, when you can hack your favorite frozen beverage by using coffee cubes instead?

The next time you brew iced coffee, whether you use a cold-brew or a hot-brew method over ice, save some of the finished drink and freeze it into your trusty ice cube tray. (If you are a cold-brew brewer, be sure to dilute it first before freezing, or prepare to bounce off the walls.)

For a stronger drink, use as many iced-coffee-cubes as you would regular ice cubes; for a mellower drink, use half of each type.

As the frozen coffee melts, it will blend into your beverage instead of diluting it, maintaining a kick that will stand up even to added milk or cream.

Just don’t freeze still-hot coffee or use leftovers you’d otherwise dump down the drain. The bitter-tasting compounds in hot-brewed coffee will ultimately break down and turn sour even before they freeze, and nobody wants a sour summer. You also don’t want to use coffee cubes as the ice base for a flash-chilled brew, or your finished drink will be overpowering (and probably pretty bitter).

When a fancy mood strikes, mix cinnamon, a dash of vanilla, or chocolate syrup into the cubes for a DIY flavor boost. You can also use coffee ice cubes to blend into frozen cocktails, shakes, or smoothies, or crush them for a homemade granita, topped with fresh whipped cream. Drop a couple into a chilled glass with fizzy water and simple syrup for a spin on a coffee soda; experiment with tonic and homemade or store-bought syrups. (Just be sure to clean the trays thoroughly before starting your next batch!)
