What is the milk level in a Grande iced flat white?

In a Grande iced flat white, the milk level reaches the top line of the cup. This is important because the iced flat white is designed to maintain the correct balance of flavors between the espresso and the milk. A Grande size typically holds 16 ounces, and filling the cup to the top line ensures that the drink includes the appropriate amount of steamed milk and espresso shots, resulting in the intended rich and creamy texture.

Additionally, the flat white is characterized by its velvety microfoam and robust coffee flavor, which means using the full milk volume is crucial to balance with the intensity of the espresso. Therefore, if less milk were used, as indicated by the other options, it could affect the drink's signature consistency and taste.
