What is the pour size for a classic "single shot" cocktail?

The standard pour size for a classic "single shot" cocktail is 1.5 ounces. This measurement is widely recognized in bartending and is often used as the baseline for most cocktail recipes. A single shot provides the right amount of spirit to mix well with other ingredients, ensuring a balanced flavor in the drink.

For reference, a one-ounce pour is typically considered a "half shot" and sizes larger than the standard single shot, such as two ounces or more, are generally used for stronger drinks or doubles. Using 1.5 ounces allows bartenders to create cocktails with a consistent taste and ensures that patrons receive a properly measured serving.
