Which ingredient is omitted in a Tall Iced Salted Caramel Mocha compared to a Grande?

In a Tall Iced Salted Caramel Mocha, the difference in size from a Grande affects the number of espresso shots included in the drink. Specifically, a Tall size typically has one shot of espresso, while a Grande contains two shots. This reduction in espresso is essential for maintaining the balance of flavors, as smaller sizes are formulated to maintain that flavor profile with fewer ingredients.

The other ingredients, such as mocha sauce and toffee nut syrup, remain the same in both sizes to ensure that the taste is consistent at different volumes. Similarly, the milk used in the drink is also adjusted according to the size but does not get omitted in the same way as the espresso shot does. This nuance in espresso shots is what distinguishes the Tall from the Grande, making it a key aspect of the Starbucks menu preparation for varying drink sizes.
