What Are Jiggers Used For When Making Drinks?

Bartenders have many tools at their disposal to craft the perfect vodka martini with a twist, negroni, Moscow mule, or whatever the adult beverage of choice might be. But perhaps one of the most important tools that helps ensure they are pouring just the right amount of alcohol into a cocktail is called a jigger, a double-sided shot glass that can measure as small as half an ounce to as much as 2.5 ounces of liquid. 

Just like measuring cups you use for cooking and baking, jiggers can come in several different sizes. But the most common type of jigger measures 1.5 ounces on one side, and 0.75 ounces on the other, making it great for measuring out shots in drinks. However, if you are worried about how you can tell what size your jigger is, don't — many jiggers have markings on the outside of the cup to let you know how much alcohol they hold. 

Jiggers can be made out of metal, glass, or plastic, and you might be surprised to learn that there are several different types. While the double jigger is the standard, there is also something called a Japanese jigger, which is slimmer and is measured in a 1:1 ratio. This is used for drinks that have equal parts. The Japanese jigger may be the most practical and precise jigger to use, except when pouring syrups. Aside from these options, there is also the bell jigger, which has a rounder, bell-shaped bowl that helps avoid alcohol from spilling over the sides when you pour it.

In addition to using these measuring tools for the correct amount of alcohol, you can also use a jigger to help with layered cocktails. These drinks are beautiful to look at, as they are typically poured according to the alcohol that has the greatest density, and then topped with juice and syrup.
