To achieve a perfect blend, exact measurements should be taken when mixing drinks. If bakers have measuring cups, bar tenders have the shot glass to do just that. This is a small glass that measures liquor. It holds a certain amount of wine to be mixed into a cocktail or drunk straight from the glass. They are available in common sizes of small, single and double.

Shot glass is also called whiskey tumblers which are made for the purpose of drinking alcoholic beverage in small amounts. There are varieties that are made of plastic or metal. But traditionally, shot glasses are made of glass. They do not have handles, or stems, or feet. At present, they come in different styles and shapes with round being the most popular.
