How Do Calories Differ with White Rum Cocktails?

Understanding the caloric breakdown of white rum on its own is a great first step but equally important is being mindful of the other ingredients that make it into your chosen rum-based beverage. A Pina Colada will likely have more calories than a Daiquiri due to the added fruits and ingredients.
