Highball glasses are tall, straight-sided drinking vessels typically used for serving mixed drinks. They usually hold between 8 to 12 ounces and are designed to accommodate cocktails that include a spirit and a non-alcoholic mixer, such as soda or tonic water. The glass's height allows for plenty of ice, making it ideal for refreshing beverages. These glasses are often made from glass or crystal and can come in various designs, from simple to ornate. Common cocktails served in highball glasses include the whiskey highball and the gin and tonic. Their versatility makes them a staple in bars and homes alike.
