What is the legal measurement of a standard jigger?

The legal measurement of a standard jigger is 1.5 ounces. This measurement is widely accepted in the bar and spirits industry and serves as a common standard for bartenders when measuring spirits for cocktails and mixed drinks. The use of a jigger ensures accuracy and consistency in drink preparation, which is essential for both delivering the intended flavor profile and managing portion control effectively.

The 1.5-ounce measurement aligns with industry practices, particularly in the United States, where this size is recognized as a standard unit for alcoholic beverage measurements. Understanding this standard is vital for professionals in the field, as it also aids in compliance with legal serving sizes and responsible alcohol service.
