What does the "proof" mean when describing alcohol?!


Question: What does the "proof" mean when describing alcohol!?
Answers:
take the alcohol percent and double it!.

40% = 80 proofWww@FoodAQ@Com

its the percentage of alcohol in it so like golden grain is 180 proof which means it is 90% alcohol!. Basically you half the proof and you have the percentage of alcoholWww@FoodAQ@Com

Alcoholic proof is a measure of how much ethanol is in an alcoholic beverage, and is approximately twice the percentage of alcohol by volumeWww@FoodAQ@Com

The proof is a measure of the amount of alcohol!. If you divide it by two, you get the percentage of alcohol!. for example, 90 proof would be 45% alcohol!.Www@FoodAQ@Com

I have no idea why we have proof and percentages and not just one or the other, but I do know that proof is percent x 2!.

45% = 90 proof!.

Oh, thanks to Rose, now I know!.Www@FoodAQ@Com

it only means the concentration of alcohol--Www@FoodAQ@Com

The amount of alcohol content!. Why they use 'proof' I'm not sure!. It equals twice the alcohol percentage!.!. So 40 proof has 20% alcohol and 80 proof has 40% alcohol!.Www@FoodAQ@Com

every one is right!. the term proof comes from the pioneer way to judge alcohol content!. when doused with the alcohol, gun powder will burn(and burn blue) if the content is 50% alcohol(100 proof) this is the "proof" of booze!. and yes , proof is twice the amount of alcohol content!.Www@FoodAQ@Com

When liquor is 100 proof it will burn!. That's 50% alcohol!. So overproof alcohol has more than 50% alcohol, and say 40 proof will contain 20% alcohol!.Www@FoodAQ@Com

It's a reference to the Alcohol By Volume (ABV) contained in the spirit (scotch, vodka, etc!.!.!.)!.

A bottle of rum that’s labeled 90 proof is 46% ABV!.

The reference of “proof” is only used with distilled spirits!. Wines and beers are listed as percentages!.Www@FoodAQ@Com
