Glögg Day is observed in Sweden every December 1 to celebrate the traditional Nordic drink known as glögg, a hot mulled wine that is especially popular during the winter season and around Christmas. This drink has its origins in Sweden and can be traced back to at least the 16th century, with the first recorded mention of "glödgat vin" occurring in 1609. Traditionally, glögg is made with red wine and a variety of spices such as cinnamon, cloves, and cardamom, and it can also be prepared non-alcoholically using juice. On Glögg Day, Swedes enjoy drinking glögg, experimenting with different recipes, and gathering with loved ones to embrace the Christmas spirit. The day marks the beginning of the Christmas season, during which glögg is commonly served alongside snacks like gingerbread and saffron buns.
