Why: Doing some basic alcoholic math. Liquor is generally sold in 750 mL bottles, and 1 shot = 1.5 fl oz
Answer: 750 mL = 25.36 f.l oz (because 1 mL = 0.033 fl oz)
So 25.5 (per bottle) / 1.5 (per shot) = 17 single shots per bottle
However! There are 2.5 fl oz in a double shot (not 3), so that means a little more than 10 doubles in a bottle!
