What is the correct ice scoop size for a venti caramel flan frappuccino?

The venti scoop is the appropriate choice for a venti caramel flan frappuccino because each drink size at Starbucks is designed to use a specific scoop that corresponds to its volume. The venti size is the largest of the standard drink sizes offered, typically holding 24 ounces. Therefore, the venti scoop is specifically sized to accommodate the ice quantity needed to properly chill and blend the beverage to maintain its intended flavor and texture. By utilizing the venti scoop, the appropriate amount of ice is ensured, resulting in a balanced and enjoyable drink experience for customers. This attention to detail is crucial in keeping the flavors consistent across different sizes of the drink.
