In which frappuccino recipe is the term "frapp roast" used?

The term "frapp roast" refers specifically to a coffee base used in certain Frappuccino beverages at Starbucks. It is a type of coffee concentrate made from Starbucks' signature blend of coffee, which provides a robust coffee flavor in blended beverages.

In the context of the Eggnog Frappuccino, the frapp roast is included to complement the creamy eggnog and spices typically associated with this seasonal drink. This combination enriches the flavor profile, providing depth to the sweetness of the eggnog and balancing it with the sharpness of the coffee notes.

The other choices do not involve "frapp roast" in their preparation. Beverages like the Coconut Frappuccino and Chocolate Cookie Crumble Frappuccino use different types of bases and flavorings that do not require the coffee concentrate. Instead, they focus on flavors from ingredients like coconut or chocolate cookies, respectively. The Gingerbread Frappuccino also leans more towards the dessert and spice flavors without integrating "frapp roast" as an element in its recipe.
