A 16oz can of Heineken Premium Lager Beer contains 5% ABV.
Alcohol by volume (ABV) simply represents what portion of the total volume of liquid is alcohol.
And to determine the ABV of a beer, a brewer typically uses what's called a hydrometer, which is an instrument that aids in measuring the density of liquid in relation to water (it essentially free-floats in a cylinder or liquid).
The hydrometer will be calibrated to read 1.000 in water (at 60°F), and the denser the liquid (example: add sugar to the liquid), the higher the hydrometer reading. Learn more about ABV on BeerAdvocate.com.
