Which of these beverages uses espresso as a primary ingredient?

The White Chocolate Mocha contains espresso as a primary ingredient, making it a key component of this beverage. This drink is a combination of rich white chocolate sauce, steamed milk, and espresso, delivering a smooth and sweet flavor profile that’s characteristic of coffee beverages. Espresso serves as the base, providing the caffeine and strong coffee flavor that is essential to this type of mocha.

The Caramel Macchiato also includes espresso, but it is crafted with layers of vanilla syrup, steamed milk, foam, and a caramel drizzle on top of the espresso. The emphasis on espresso in the context of this question leads to the distinction that while both the White Chocolate Mocha and Caramel Macchiato utilize espresso, the former puts it forward as the primary ingredient alongside its sweetening elements.

Products like the Double Chocolaty Chip and Blended Strawberry Lemonade do not include espresso. Instead, they are based on chocolate and fruit flavors, respectively, with no coffee elements involved, further supporting the reasoning behind selecting the White Chocolate Mocha as the correct answer. Thus, the focus on espresso as the core ingredient in the White Chocolate Mocha solidifies its place as the right choice in this selection.
