What is the number of shots used for a tall double shot on ice?

In a tall iced beverage at Starbucks, a double shot refers specifically to the espresso used in the drink. For a tall size, which is typically 12 ounces, the standard number of espresso shots is two. Therefore, when a tall drink is ordered as a double shot on ice, it is served with two shots of espresso. This consistency in size means that the number of espresso shots remains the same regardless of whether it is served hot or iced.

The other options reflect incorrect shot amounts for this specific drink size and preparation method. For example, a single shot would not meet the definition of a double shot, and three or four shots would be excessive for a standard tall drink. Having two shots aligns with Starbucks' standard practice for espresso in a tall-sized iced beverage.
