How is a venti frappuccino typically distinguished in preparation from a tall frappuccino?

A venti frappuccino is distinguished from a tall frappuccino mainly by the increased pump count of flavoring syrup used in its preparation. When creating a frappuccino, the size of the drink dictates how many pumps of syrup are added to achieve the desired flavor intensity. For a venti size, which is larger, more pumps of syrup are required compared to a tall, ensuring that the flavor remains balanced despite the increase in volume.

This adjustment is necessary because a larger drink would dilute the flavors if the same amount of syrup as in a smaller size were used. Thus, the increase in pump count is crucial for maintaining the intended taste experience in each size. The other options do not primarily differentiate between a tall and a venti frappuccino in the same significant way that the pump count does.
