A fifth of liquor, a common 750 ml bottle size (about 25.4 ounces), typically yields around 17 standard 1.5-ounce shots in the US.

Quick Math Breakdown

Divide the bottle's volume by shot size: 25.4 oz ÷ 1.5 oz ≈ 16.9 shots, often rounded to 17 for practical use. This assumes precise pours; real-world factors like overpouring can drop it to 16.

Variations by Shot Size

  • Standard US shot (1.5 oz) : ~17 shots.
  • Smaller bar shot (1.25 oz) : Up to 20 shots.
  • Generous shot (1.75 oz) : About 14-15 shots.
  • Double shot (3 oz) : Roughly 8-9 doubles.

Shot glass capacity and regional standards (e.g., 25-50 ml elsewhere) affect counts, but US bartending sticks close to 1.5 oz.

TL;DR : Expect 16-17 shots per fifth for most scenarios.
