What is the standard pour size for a shot of liquor?

The standard pour size for a shot of liquor is 1.5 ounces. This measurement is widely recognized in the bartending industry and is used as a standard for serving spirits in bars and restaurants. It provides a consistent amount that ensures customers receive a fair serving without being short-changed. The 1.5-ounce pour is also practical for mixing drinks, as it balances well with other ingredients in cocktails. This standardization helps to maintain consistency across different establishments and ensures that guests have a similar experience regardless of where they are served.

While the other options represent various pour sizes, they do not align with the industry standard for a shot. Knowing the correct pour size is essential for bartenders as it plays a significant role in accurately crafting cocktail recipes and managing inventory effectively.
