When preparing the Venti Iced Caffe Americano, how much cold water is added?

For a Venti Iced Caffe Americano, cold water is added to the top line on the cup. This method is essential because the Iced Caffe Americano consists of espresso shots poured over cold water, and the top line indicates the correct amount of water needed to balance the espresso.

Using the top line ensures that the drink has a proper dilution, allowing the flavors of the espresso to be present while still achieving the desired iced beverage experience. This preparation technique helps maintain consistency across different servings and complies with Starbucks' standardized recipes, leading to a favorable customer experience.
