How much ice is added to all the iced caffe drinks after adding other ingredients?

In iced caffe drinks at Starbucks, ice is typically added up to the top line of the cup after the other ingredients, such as espresso and milk, have been introduced. This practice ensures that the drink has the desired level of coldness and dilution when served, while also maintaining the overall volume and balance of flavors. Adding ice to the top line allows for sufficient room for the drink’s components, ensuring a well-mixed and refreshing beverage. This method of preparing iced drinks is standard across various iced options in the menu, emphasizing consistency in the customer experience.
