Which modification indicates the use of a base in coffee drinks?

The use of a "mocha base" is indicative of incorporating a base into coffee drinks because it refers to a specific form of mix that serves as the foundational flavor profile for beverages. In this context, a base is a concentrated blend, usually consisting of chocolate, and is often pre-prepared to ensure consistency in flavor and texture across different servings. By using a mocha base, baristas can create a uniform taste that enhances the overall experience of the coffee drink.

In contrast, options like mocha drizzle, no ice, and whipped cream do not inherently indicate the presence of a base in coffee drinks. Mocha drizzle is a finishing touch added for decoration and sweetness, while no ice simply refers to the serving style of the drink and doesn’t contribute to the flavor foundation. Whipped cream is a topper that adds creaminess and richness but does not function as a base. Thus, the "mocha base" distinctly identifies the essential ingredient that creates the core flavor profile in mocha-flavored coffee beverages.
