Which size mocha has the most pumps of mocha syrup?

The choice of the Venti mocha is correct because Starbucks sizes follow a specific ratio of syrup pumps to beverage. In a Venti size, which is 20 ounces for hot drinks, there are typically 5 pumps of mocha syrup. This is greater than what is offered in the Tall size, which has 3 pumps, the Grande size that has 4 pumps, and the Short size that has 2 pumps.

The design of the drink sizes establishes a proportional increase in flavoring as the size increases, meaning that the largest size will always have the most mocha syrup to ensure a balanced flavor experience for customers. This makes the Venti mocha the option with the most pumps of mocha syrup among the sizes listed.
