Serving and garnishing the mulled wine is an important aspect of the overall experience. When serving gluhwein, use heatproof glass mugs to maintain the warmth of the drink and allow the aromatic steam to rise. Garnishing each serving with a fresh cinnamon stick or an orange slice adds a festive touch and enhances the visual appeal of the drink. The combination of aroma, flavor, and presentation creates an inviting and heartwarming experience for all who partake in this beloved holiday beverage.
