Helpful tip: To avoid watering down the flavor, make sure to let the coffee cool before adding ice.

Tips for Making the Perfect Cup of Iced Coffee

1. Make Cold-Brewed Coffee Instead

When making iced coffee, it’s best to use room-temperature coffee. This will reduce the amount of ice that’s melted when you pour the coffee over it.

3. Add Ice Cubes

To keep your iced coffee chilled, add ice cubes to your glass before pouring in the coffee. This method can help prevent diluting the coffee’s flavor and keep it fresh and cool.

4. Consider Adding Milk or Cream

If you prefer a creamier taste, consider adding milk or cream to your iced coffee. This addition can help balance the coffee’s acidity and add a velvety texture to your drink.

5. Use Quality Coffee Beans

To ensure the best taste and flavor, always use quality coffee beans when making iced coffee. Spirit Animal Coffee offers an excellent selection of coffee beans.
