What is the primary spirit in a classic Mojito?

The primary spirit in a classic Mojito is light rum. This choice is essential because light rum, known for its clean and crisp flavor, complements the fresh ingredients in a Mojito, including mint, lime, sugar, and soda water. The light rum provides a subtle sweetness and body without overpowering the other flavors, which is crucial in achieving the refreshing profile characteristic of this cocktail.

Light rum is typically unaged or lightly aged, which allows it to maintain a lighter, more delicate taste that works harmoniously with the acidity of the lime and the brightness of the mint. This makes it the ideal spirit for this classic Cuban drink, creating a well-balanced and refreshing beverage that highlights its ingredients. Other spirits, such as dark rum or whiskey, would introduce flavors that are too rich or complex for a traditional Mojito, which is meant to be a refreshing summer drink.
