Which drink contains the least amount of peppermint syrup?

The short peppermint mocha contains the least amount of peppermint syrup because it is the smallest size available in the Starbucks lineup. In general, smaller sizes of drinks have less of each component, including syrup. A short drink is designed to provide a smaller portion, making it ideal for someone looking for a milder flavor or smaller serving of a specific ingredient, such as peppermint syrup.

In contrast, the tall and grande sizes inherently contain more syrup and overall volume, which can lead to a stronger flavor profile. This is essential for understanding how Starbucks sizes affect the overall drink composition.
