The primary ingredient in mulled wine is red wine. This warm, spiced beverage is traditionally made by heating red wine with a variety of spices, fruits, and sometimes sweeteners. Ingredients commonly added include cinnamon sticks, cloves, star anise, citrus fruits like oranges or lemons, and sugar or honey. The concoction is usually gently simmered to allow the flavors to meld together, creating a cozy and aromatic drink popular during the winter months, especially around the holiday season. Mulled wine has its origins in ancient times, where wine was often heated for preservation and flavor enhancement.
