Bar Tool

Jigger

Also known as: measure, shot measure, pony measure

A double-sided measuring tool used to precisely measure liquid ingredients for cocktails, typically with two different capacities on each end.

The jigger is essential for consistent cocktails. Standard jiggers measure 1.5 oz (45ml) on one side and 0.75 oz (22ml) on the other, though Japanese-style jiggers often measure 1 oz and 2 oz. The name comes from an old English unit of measurement. Professional bartenders use jiggers to ensure every drink tastes identical, which is crucial for customer satisfaction and cost control.

💡 Pro Tips

Fill to the very top for accuracy - surface tension allows a slight dome
Use the smaller side for modifiers like bitters or liqueurs
Japanese-style jiggers with interior lines offer more measurement options

⚠️ Common Mistakes to Avoid

Eyeballing measurements instead of using a jigger
Not leveling off the liquid at the top
Using a shot glass instead of a proper jigger
