What type of glass is typically used for a Cosmopolitan?

The Cosmopolitan cocktail is traditionally served in a Martini glass, which is perfectly suited for its elegant presentation. The wide, shallow bowl of the Martini glass allows for a greater surface area, showcasing the vibrant color of the Cosmopolitan and enhancing the aroma of its ingredients. This style of glass also emphasizes the drink's sophistication, making it a favorite for such cocktails.

Using a Rocks glass would not highlight the drink’s delicate ingredients and presentation, while a Flute glass is typically reserved for sparkling wines and does not accommodate the same cocktail aesthetics or volume. A Regular glass, which lacks the specific shape and design features of a Martini glass, would not effectively convey the expected experience for a Cosmopolitan. Therefore, the Martini glass is the ideal choice for serving this stylish cocktail, contributing to both its visual appeal and enjoyment.
