What drink has the highest caffeine content?

The drink with the highest caffeine content is the cortadito. A cortadito is a traditional Cuban coffee drink that combines espresso with a small amount of steamed milk, resulting in a strong and rich flavor. The significant component here is the espresso, which is known for its high caffeine concentration compared to other types of beverages.

In contrast, options like the regular mojito, white coconut creme, and strawberry guava do not contain significant amounts of caffeine, as they are primarily composed of non-caffeinated ingredients such as soda, milk, coconut, and fruit. Therefore, while the white coconut creme can be a delicious option, it does not have caffeine in the same way that a cortadito does, making it an unsuitable answer for this question regarding caffeine content.
