What distinguishes a Cuba Libre from a Rum and Coke?

The primary distinction between a Cuba Libre and a Rum and Coke lies in the addition of a lime wedge. While both drinks contain rum and cola, the Cuba Libre is specifically characterized by the inclusion of fresh lime juice or a lime wedge, which adds a citrusy flavor that enhances the overall taste of the drink. The lime element is essential, as it not only contributes acidity but also balances the sweetness of the cola, creating a more refreshing cocktail.

In contrast, a Rum and Coke typically does not involve any additional citrus and is considered a simpler drink. The choice of rum, alcohol content, or type of glass do not fundamentally alter the identity of a Cuba Libre as intimately as the addition of lime does. This citrus component plays a crucial role in elevating the Cuba Libre from being just a basic mixed drink into a more sophisticated cocktail experience.
