The traditional German mulled wine, or glühwein, is a cherished beverage that embodies the essence of the holiday season. When making gluhwein at home, it's crucial to select the best wine to serve as the foundation for this beloved drink. Opt for a dry red wine with robust flavors, such as a Cabernet Sauvignon, to ensure that the wine provides a strong base for the infusion of spices and retains its rich character even after heating.
