"Alcoholic proof is a measure of how much alcohol (i.e., ethanol) is contained in an alcoholic beverage. The measure is commonly used in the United States, where it is defined as twice the percentage of alcohol by volume."

The answer varies in each different liquor, and should be listed on the bottle as "proof". The "Proof" is twice the alcohol percentage, so 40 proof is 20% alcohol, 180 proof is 90% alcohol.
Double the percent alcohol. 40% alc is 80 proof. 200 proof is pure alc.
1 ounce = 28.3495 grams; 200 alcohol proof = 100% alcohol content. 2 ounces of 80 proof (40% alcohol) whiskey would be 56.699 grams of whiskey with 22.6796 grams of pure alcohol.
The "Proof" of an alcoholic beverage is an indicator of it's alcohol content on a 200 point scale. Take the Proof # and divide it by 2 to find out what the percentage is. So, to answer you specific question, 86/2= 43. Therefore 86 proof alcohol is 43 percent alcohol.
Pure Grain Alcohol; usually containing a very high alcohol proof/percentage (i.e. 100 Proof, 50%)
It signifies the "strength" of the liquor, and can give you an estimate of how much alcohol is in the drink by percentage. For example, if you have a 1.5oz of a 40% ABV spirit, 0.6oz is pure alcohol.
100% pure alcohol is 200 proof. A liquid containing 10.5% alcohol would thus be 21 proof
In the US, a "standard" drink is 0.6 ounces of pure alcohol, regardless of the beverage involved.
30% of however much you drank... e.g. You drank a 50ml shot of 60 proof = 15ml of 'pure' alcohol
Which drink is stronger in terms of pure alcohol? A glass of wine, a mug of beer, a shot of liquor, or are they all the same?The answer is:A shot of liquor
In the U.S., proof equals twice the percentage of alcohol in the beverage. In the UK, and several European countries, the 'proof' of alcohol is not given, it is stated as a percentage of volume. However this is somewhat misleading. Pure alcohol, which would be 100% alcohol, very difficult to produce, would be classed as 200 proof. Confusing to the uninitiated. All spirit drinks sold retail in the UK must state their alcohol by volume and not their 'proof'.
If it's pure alcohol... none.
