What ingredient is drizzled on top of the Hot 151 Macchiato?

The Hot 151 Macchiato features a drizzle of caramel on top, which adds both a sweet flavor and a visually appealing touch to the drink. Caramel not only enhances the overall taste profile but complements the coffee's rich and robust characteristics, making it a delightful choice for those who enjoy a sweeter beverage. Its smooth, rich texture contrasts nicely with the macchiato's espresso layer, creating a well-balanced drink.

In this context, while other flavoring options such as cinnamon, vanilla, and Irish cream might be popular in various coffee preparations, none are specified as the signature topping for the Hot 151 Macchiato like caramel is. Each of those alternatives could be used in different recipes or drinks, but caramel specifically enhances the macchiato experience in this case.
