A highball glass holds 8 to 12 ounces of liquid. Highball glasses are designed to hold drinks that include a shot of liquor and several ounces of juice or soda, along with a generous amount of ice.
Examples of drinks usually served in a highball glass include the scotch and soda, rum and Coke, bloody Mary and screwdriver, which is made from vodka and orange juice. A Collins glass is similar in shape and capacity to a highball glass, although the Collins glass is usually taller and thinner. The two glasses can be used interchangeably for drink recipes that require a large quantity of mixer.
