The most popular beverage during the time of the Aztecs was Chocolatl, which is closest to option 4 in the provided list. The Aztecs, along with the Mayans and the Olmecs before them, cultivated cacao beans which were a significant part of their culture and economy. The beans were made into a paste, thinned with water, and sweeteners like honey were added to create chocolatl. It was a drink that held great importance, often consumed by elites, warriors, merchants, priests, and nobles in the society and was also used in various rituals and ceremonies. With its introduction to Europeans by the Aztecs and the Spaniards who witnessed the consumption of chocolatl, it eventually became a widely enjoyed drink in Europe as well.
