20 g = 0.705479 oz What’s that, about one sip? Doesn’t sound like much.

Maybe they mean 20 grams of alcohol, so at, say, 16 proof, that would be about one cup. (just guessing here.)

>> Maybe they mean 20 grams of alcohol

That’s exactly what they mean.

It’s about a “drink”, more or less. A beer, a glass of wine, a jigger in a mixed drink.

A certain degree of sloppy precision is allowed here, I think.
