On alcohol bottles, why do we put the percent of alcohol AND the proof percent on? Proof is always twice the other percent, so why label both?

Consumers associate hard liquor with the phrase “80 proof” even if they don’t necessarily know what that means. Having those words on your bottle makes it look legit and signals that this is a strong drink rather than a beer/wine/mixer/liqueur. Some brands (especially “151” rums) are inextricably linked with their proof.

At the same time, ABV is a much easier measure to understand. It’s also how beers and wines are labeled. Manufacturers have enough space on the label to provide both the traditional and contemporary alcohol content information, so why not?
