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.
86 proof gin contains 43% alcohol by volume.
Proof = % alcohol x 2So vodka that's 40% alcohol by volume would be 80 proof. Wild Turkey, which is 43% percent alcohol, is 86 proof, etc.
In the US, a "standard" drink is 0.6 ounces of pure alcohol, regardless of the beverage involved.
35mL of a 43% ABV (86 US proof) beverage contains 15.05mL of ethanol.
Most whiskeys (rye) are 86 proof. Percent is half that so they are 43% alcohol. When mixed with anything in a drink they become diluted -- less alcohol %
the higher the proof the stronger - more alcohol - there is. In the UK 70 dgree proof was the standard strength of whiskey - 40% alcohol. 100 proof is 57.1% alcohol. 175 proof is 100% alcohol. In the USA it is different. 100 proof would be 50% alcohol, 70 proof would be 35% alcohol. 200proof would be 100% alcohol. ie double
proof is double the alcohol percentage. 40% alcohol= 80 proof
the proof is used to tell you how much alcohol is in it. 100 proof is about 50% alcohol so jsut divide the proof by 2 the higer the proof the more alcohol
50% alcohol Proof ÷ 2 = % alcohol
Alcohol proof is double the actual percentage of alcohol. 100 proof is 50% alcohol, 80 proof is 40%, and 65 proof is 32.5%
'Proof' is a unit of measurement equal to 1 half of 1 percent. Therefore, 150 proof is 75% Alcohol by Volume (although at this point, you're more likely drinking moonshine or grain alcohol and not whiskey)
Alcohol is measured in proof. 100% proof whiskey is 50% alcohol. Everclear is 95% alcohol.
