What type of glass is traditionally used for serving a Nutty Irishman?

A Nutty Irishman is a cocktail that typically consists of Irish cream liqueur and hazelnut liqueur, often served hot with whipped cream on top or cold in a mixed form. The traditional glass for serving this drink is the stemmed coffee glass or mug. This type of glass not only enhances the presentation of the drink but is also designed to hold hot beverages safely, providing a comfortable grip away from the hot contents. The stem allows for holding the glass without warming the drink, making it suitable for coffee-based cocktails like the Nutty Irishman.

The other glass options, such as the lowball glass, highball glass, and pint glass, are not typically associated with serving coffee cocktails. Lowball glasses are used for spirits served neat or with ice, highball glasses are meant for mixed drinks with a larger volume of mixer, and pint glasses are commonly used for beer. None of these would provide the appropriate aesthetic or functional qualities required for a Nutty Irishman.
