A highball glass is a glass tumbler that can hold contains 240 to 350 milliliters of liquid. It is used to serve highball cocktails and other mixed drinks.
These tall glasses are typically used for 'tall' mixed drinks and filled with an abundance of ice. Many times, the drinks to be served are prepared directly in the glass by pouring the ingredients over top of the ice and stirring. The simplest of these drinks will often have a shot of liquor topped with fruit juices and/or sodas to fill the glass.
Highball glass comes in a wide variety of styles. It can be plain or engraved and come in various shapes.
