Which flavor does the pump labeled "PEP" dispense?

The pump labeled "PEP" dispenses peppermint flavor. This designation aligns with standard practice in beverage preparation where "PEP" is a commonly used abbreviation for peppermint. Peppermint is a popular flavor choice, especially in seasonal drinks and offerings like peppermint mochas or holiday-themed beverages.

In context, the other flavors listed—raw sugar, maple spice, and mocha sauce—have distinct flavor profiles and applications that wouldn’t typically be abbreviated to "PEP." Raw sugar is a sweetener, maple spice is often used for a specific seasonal flavor combination, and mocha sauce refers to a chocolate-related syrup, each with different abbreviations or identifiers. Therefore, understanding the labeling system and flavor designations is crucial for correctly identifying the flavors dispensed by the pumps.
