A coupe glass is a type of stemmed glassware characterized by its shallow, broad bowl and slender stem. Typically holding between 6 to 8 ounces, it is designed to enhance the drinking experience by providing a larger surface area for the liquid, allowing for the aromas and flavors to be more pronounced. The clear glass construction showcases the drink's color and presentation, making it an elegant choice for various cocktails.

Originally used for serving champagne, the coupe glass has become popular for cocktails such as the Martini, Sidecar, and Daiquiri. Its design prevents the drink from warming too quickly, as the stem allows the drinker to hold the glass without touching the bowl. The coupe glass adds a touch of sophistication to any cocktail, making it a staple in bars and among cocktail enthusiasts.
