Cocktail glasses are specially designed vessels used to serve a variety of mixed drinks. They come in different shapes and sizes, with the most popular being the martini glass, known for its wide, shallow bowl and long stem. This design not only enhances the drink's presentation but also helps keep it chilled by minimizing contact with the hand. Other types of cocktail glasses include the highball glass for tall drinks and the coupe glass, which has a rounded bowl and is often used for serving champagne cocktails. Each glass type is crafted to enhance the drinking experience, making cocktails more enjoyable and visually appealing.
