What type of glass is typically used for serving a Dirty Martini?

A Dirty Martini is traditionally served in a lowball glass or a cocktail glass, also known as a martini glass. This type of glass has a wide, shallow bowl and a long stem, which not only enhances the drink's presentation but also makes it easier for the drinker to hold the glass without warming the content with their hand.

The shape of the cocktail glass allows for the separation of the drink's ingredients to be visually prominent, and its design helps showcase the garnish, typically an olive or two, which is essential in a Dirty Martini. The use of a lowball glass is also acceptable for serving a Dirty Martini, providing a more relaxed, informal way to enjoy this classic cocktail.

In contrast, other glass types listed in the choices do not align with the traditional presentation and serving style of a Dirty Martini. A highball glass is typically used for mixed drinks served with ice, a pint glass is reserved for beers, and a champagne flute is designed specifically for sparkling wines and champagne. Thus, the correct choice reflects both tradition and the optimal experience of enjoying a Dirty Martini.
