When it comes to making a mojito, rum is the classic go-to ingredient.  Light rums such as white or silver are best for mojitos as they provide a more subtle flavor that complements the other ingredients.   On the other hand, dark rum can overpower the taste of the cocktail and should be avoided.  If you want to make an even lighter version of this popular summertime drink, try using vodka instead of rum.  No matter what type of alcohol you choose, always make sure to use a high-quality brand for an optimal flavor experience.
