What Alcohol strength refers to the in a beverage?

Here's what it means:

* ABV is a measure of the volume of pure alcohol present in a given volume of the beverage.

* For example, a beer with an ABV of 5% means that 5% of the volume of the beer is pure ethanol alcohol.

Important Note: Alcohol strength is not the same as proof. Proof is a measure that is twice the ABV. So, a beverage with 50 proof is equivalent to 25% ABV.
