How should the ice be added to a Grande Iced Pumpkin Spice Latte?

When preparing a Grande Iced Pumpkin Spice Latte, the ice should be added to the top line of the cup. This ensures that there is enough space for the espresso and milk to mix properly while still accommodating the ice, which prevents the drink from overflowing. Adding ice to the top line helps achieve the desired balance of drink components while maintaining the overall volume of the beverage.

This method is particularly important for iced drinks because it allows the ingredients to cool evenly, resulting in a well-mixed and refreshing beverage. The top line signifies the maximum fill level, which helps baristas accurately portion iced beverages while taking into consideration the space that ice will occupy.
