What kind of glassware is commonly used for serving martinis?

The correct choice is the martini glass, which is specifically designed to enhance the presentation and drinking experience of a martini. This glass features a distinctive shape with a wide, shallow bowl and a long stem. The design serves several purposes: it allows for the ingredients to be well mixed and chilled, while also providing a wide surface area that encourages the release of the cocktail's aromas. The stem allows for the glass to be held without warming the contents with the drinker’s hand, preserving the cold temperature of the martini. This specialized glassware plays a crucial role in both the aesthetics and enjoyment of the drink, making it the ideal choice for serving martinis.
