A Jigger is a small tool that is used to measure the proper amount of alcohol that should be added to a cocktail. Jiggers can be made of metal, plastic, or glass, and come in all kinds of shapes and sizes. Jiggers are one of the most basic devices that every bartender should know how to use and utilize for making drinks. The standard jigger is shaped like an hourglass, with 1 side measuring 1.5oz, which is the size a traditional shot. The smaller side of the jigger is often called a "pony" shot and typically measures 1oz.
Modern day jiggers also come in every style and measuring unit imaginable. There are jiggers in ounce or milliliter measurements. Many bar owners prefer their bartenders to use jiggers over the free pour method that can result in bartenders over-pouring or under-pouring cocktails, and the bar eventually losing money.
Making Cocktails is technically an art, and to achieve the best tasting cocktails the perfect ratio of spirits to mixers must be used. Mixologist and bartenders everywhere can benefit from using jiggers.
