The concentration of alcohol in a beverage is usually stated as the percentage of alcohol by volume (ABV, the number of milliliters (ml) of pure ethanol in 100 ml of beverage) or as proof. In the United States, proof is twice the percentage of alcohol by volume at 60 degrees Fahrenheit (e.g. 80 proof = 40% ABV).
How can you tell if a drink has alcohol in it?
When testing individuals, the AlcoScreen will give you a reading of various shades of green/blue to indicate blood alcohol content (BAC). After 2 minutes you can determine whether BAC is at 0.02%, 0.04%, 0.08%, or 0.30% by the color of the AlcoScreen stick.
What drinks are considered alcohol?

Can you tell if water is mixed with alcohol?
Nobody can ever tell. Liquor inspectors regularly conduct audits and inspections to determine if bars are doing this.
How can you test alcohol at home?
All we need is a digital thermometer (accuracy 0.1OC or higher). Measure the difference in boiling point of wine (or beer) as compared to that of deionized water. Higher the alcohol content, lower the boiling point is. Use a degree ebulliometer reference table to compute the alcohol percentage.
Is there a litmus test for alcohol?
Alcohol is a weak acid. Most litmus paper isn’t sensitive enough to detect it.
What are the 3 types of alcohol?
In chemistry, an alcohol exists when a hydroxyl group, a pair of oxygen and hydrogen atoms, replaces the hydrogen atom in a hydrocarbon. Alcohols bind with other atoms to create secondary alcohols.
