How much liquid typically constitutes a "shot" of liquor?

A "shot" of liquor typically constitutes 1.5 ounces. This measurement is widely recognized in the bar industry and is the standard for a single serving of spirits. The 1.5-ounce shot size allows for a balanced serving, making it suitable for cocktails and straight shots alike.

In many establishments, this standardization also helps in consistent drink pricing and portion control, making it easier for bartenders to manage inventory and ensure responsible serving. Understanding this measurement is crucial for bartenders as it forms the basis for creating cocktails and serving alcoholic beverages correctly.

Larger shot sizes, such as 2 ounces or more, are less common in traditional settings and can lead to over-serving, which is an important consideration for responsible alcohol service.
