What type of glass is used for serving a Midori Sour?

A Midori Sour is typically served in a highball glass, which is designed for cocktails that contain a combination of spirits and mixers. This glass allows enough space for ice and also provides a large enough volume to accommodate the mix of Midori liqueur, sweet and sour mix, and sometimes a splash of club soda. The tall and narrow shape of a highball glass helps maintain the ideal temperature of the drink while also allowing for ample garnish options, commonly a slice of lemon or cherry.

The other types of glassware mentioned do not fit the characteristics of the Midori Sour. A coffee mug would be inappropriate as it is designed for hot beverages and does not align with the presentation of a refreshing cocktail. A rocks glass, typically used for neat spirits or cocktails served straight up with ice, would not enhance the drink's aesthetics like a highball glass does. Lastly, a cocktail glass is generally reserved for drinks served straight up without ice, such as martinis or daiquiris, which is not the case for a Midori Sour that is enjoyed over ice.
