How many ristretto shots are included in a Venti iced flat white?

A Venti iced flat white contains four ristretto shots of espresso. This is consistent with the standard practice for a flat white, which typically emphasizes the rich and smooth flavor profile produced by the ristretto method. Ristretto shots are a shorter pull of espresso that results in a more concentrated and sweeter flavor, making them particularly well-suited for drinks like the flat white, where the balance of coffee and milk is crucial for the desired taste.

In this case, the choice of four shots allows for a robust coffee flavor that stands up well against the creaminess of the milk used in the drink, creating a harmonious blend that is a hallmark of a well-crafted flat white. Other options do not align with the standard preparation for this specific beverage at Starbucks, which is why they are less applicable.
