Which type of glass is used for serving Irish Coffee?

The correct type of glass for serving Irish Coffee is indeed a coffee mug. This choice is ideal because the design of a coffee mug, typically made of heat-resistant glass or ceramic, allows for both the presentation and functionality needed when serving this hot beverage. The mug’s handle provides a way to hold the drink comfortably without risking burns, while the transparent or semi-transparent material showcases the beautiful layers of Irish coffee, which usually consists of strong brewed coffee, Irish whiskey, sugar, and a layer of cream on top.

In contrast, options like a highball glass, flute, or martini glass do not fit the traditional serving method for Irish Coffee. Highball glasses are typically used for mixed drinks served with ice, flutes are designed for sparkling wines and champagne, while martini glasses are meant for cocktails served straight up. None of these alternatives offer the practicality or the appropriate aesthetic presentation for a warm, layered coffee drink.
