Which size frappuccino uses 3 pumps of base syrup in a mocha frappuccino?

In a mocha frappuccino, the grande size utilizes 3 pumps of base syrup. The grande size is typically 16 ounces, which is designed to provide a balanced flavor profile that incorporates the necessary sweetness and richness from the base syrup, complementing the coffee and chocolate components of the drink. This formulation is standard across many of the frappuccino recipes at Starbucks to ensure a consistent experience for customers.

The other sizes use different amounts of base syrup: the tall size has 2 pumps, the venti uses 4 pumps, and the short size caters to those looking for a smaller option and contains fewer pumps of base syrup, which makes them distinct from the grande size. This variability in syrup pumps helps tailor each drink's sweetness and intensity to the size preference of the customer while maintaining the overall intended flavor experience of the frappuccino.
