What distinguishes a mocha from a latte?

A mocha is distinguished from a latte primarily by the inclusion of chocolate syrup. This is the key characteristic that sets the mocha apart, as it combines espresso, steamed milk, and chocolate flavoring, resulting in a rich, sweet beverage that has the distinct taste of chocolate. In contrast, a latte consists solely of espresso and steamed milk, focusing on the combination of coffee and milk without any additional flavors.

While some other options touch on aspects of preparation or temperature, they do not accurately define how a mocha differs from a latte. The presence of chocolate syrup in a mocha is what gives it a unique flavor profile, making it a popular choice among those looking for a coffee drink that combines the richness of chocolate with the boldness of espresso.
