Your menu lists a 142 ml glass of 12% wine and a 43 ml shot of 40% whisky. A guest says the shot must hit harder because it is stronger. What do you tell him?
Option A: The shot holds more alcohol because it is 40%
Option B: The wine holds more alcohol because the glass is bigger
Option C: Both hold about the same alcohol, one standard drink each
Correct answerOption D: Spirits are counted differently from wine
Explanation
Both pours hold about 17 ml of pure alcohol, so both are one standard drink. The shot is stronger and much smaller, the wine is weaker and much bigger, and the alcohol works out the same. Strength on its own never gives you the count, and neither does glass size. You need both numbers.
