How Many Ounces Are In A Shot?

If you’ve ever ordered a drink at a bar, you’ve probably wondered how many ounces are in a shot. The quick answer is 1.5 ounces and there’s a reason for it, and that reason has everything to do with history and tradition.

The Origins of the Shot Glass

The shot glass as we know it today originated in the 18th century. At that time, it was common for bartenders to free-pour drinks for their customers. However, this led to a lot of inconsistency between drinks, with some being stronger than others.

In order to solve this problem, bartenders started measuring out their drinks using shot glasses. This ensured that each drink contained the same amount of alcohol, making for a more consistent experience for customers.

Why 1.5 Ounces?

Nowadays, 1.5 ounces is the standard size for a shot glass, but this wasn’t always the case. In fact, the original shot glasses held only 1 ounce of liquid. It wasn’t until the early 20th century that the size of the shot glass was increased to 1.5 ounces.

The reason for this change was twofold: first, by increasing the size of the shot glass, bartenders were able to pour drinks more quickly; and second, by serving drinks in slightly larger glasses, bars were able to increase their profits by selling more alcohol without raising prices.
