National Coquito Day is celebrated worldwide every December 21 to honor coquito, a traditional Puerto Rican Christmas drink. This coconut-based beverage, whose name translates to "little coconut," is made primarily from rum, coconut milk, coconut cream, and sweetened condensed milk. While the exact origins of coquito are unclear, it is believed to have been introduced during Spanish colonization, evolving from eggnog recipes that incorporated local rum. Coquito is often flavored with spices like vanilla, cinnamon, and nutmeg, and variations can include ingredients such as pumpkin for a Thanksgiving version known as coquito de calabaza. The holiday was founded in 2018 by Don Q, a Puerto Rican rum brand, and is best celebrated by making and sharing coquito with friends and family, often during themed Christmas gatherings.
