Brew your coffee: Start by brewing a cup of strong coffee using your preferred method, such as a drip coffee maker, French press, or pour-over.

Chill the coffee: Let the coffee cool to room temperature or refrigerate it for at least 30 minutes to chill.

Fill a glass with ice: Add ice cubes to a tall glass until it's about 2/3 full.

Pour the chilled coffee: Pour the chilled coffee over the ice cubes in the glass.

Add milk and sugar (optional): If desired, add milk or a creamer to the coffee and stir well. You can also add sugar or a sweetener to taste

Add flavorings (optional): If you want to give your ice coffee a unique flavor, now's the time to add vanilla, hazelnut, or cinnamon syrup.

Stir and serve: Stir the coffee well and serve immediately.
