What is the primary purpose of adding sugar or flavor to an Iced Latte?

The primary purpose of adding sugar or flavor to an Iced Latte is to enhance sweetness and taste. Sweetness can significantly improve the overall flavor profile of the drink, making it more enjoyable for customers who may prefer a sweeter beverage. By incorporating sugar or flavored syrups, you are able to balance the robustness of the espresso with complementary flavors, creating a more appealing drink.

While cooling down the espresso is a concern when preparing an iced beverage, the addition of sugar or flavor is not aimed at this. Similarly, the addition of these elements does not contribute to making the drink thicker or significantly increasing its volume; they are primarily enhancements to the flavor experience. Thus, the inclusion of sugar or flavor serves the purpose of appealing to customer preferences and enhancing the beverage's overall taste.
