What is added to the top of a Grande iced caramel macchiato?

A Grande iced caramel macchiato features a layer of caramel drizzle added to the top of the drink. This caramel drizzle not only enhances the aesthetic appeal of the beverage but also contributes a rich, sweet flavor that complements the espresso and milk in the drink. The balance of the coffee and the sweetness from the caramel is key to the overall experience of the iced caramel macchiato.

While other toppings like chocolate drizzle or whipped cream might be common in various Starbucks beverages, they are not included in the standard recipe for this particular drink. The lack of any toppings would not provide the intended flavor profile either, as the caramel drizzle is a signature element that defines the drink. Thus, the addition of caramel drizzle is what makes the Grande iced caramel macchiato special and consistent with its intended flavor profile.
