Which cocktail is characterized by being served warm in a glass mug?

The cocktail characterized by being served warm in a glass mug is Hot Skadi. This drink is typically made with ingredients like spiced rum and hot beverages, making it perfect for colder weather or as a warming pick-me-up. The use of a glass mug is significant, as it not only keeps the beverage warm but also allows the drinker to appreciate the visual appeal of the steaming ingredients within. This presentation is common for hot cocktails, which often aim to evoke a cozy, comforting experience.

Other cocktails like the Huckleberry Lemondrop, Dill With It, and The Viking are generally served chilled or at room temperature, showcasing different flavor profiles and serving styles that do not align with the warm presentation that characterizes Hot Skadi.
