What is the primary sweetener in a classic Daiquiri?

In a classic Daiquiri, the primary sweetener used is simple syrup. Simple syrup is a mixture of sugar and water that has been heated to dissolve the sugar, creating a smooth, easily mixable liquid sweetener. This allows for a balanced flavor profile in the cocktail, as the sweetness complements the acidity of the fresh lime juice and the warmth of the rum.

While other sweeteners such as honey or agave syrup can be used in various adaptations of the Daiquiri or in different cocktails, they are not traditionally recognized in a classic version. The classic Daiquiri recipe emphasizes the use of simple syrup to maintain a clean and consistent flavor, which is why it is the correct answer for this particular question.
