How drunk you get depends on how much pure alcohol your drink contains. One way to calculate this is by counting units. One unit is 10 ml of pure alcohol. It takes the average adult around an hour to process this so that there’s none left in their bloodstream, although this varies from person to person. The alcohol content in drinks is also expressed as a percentage of the whole drink. Familiarize yourself with the alcohol percentages of your favorite drinks by learning about the alcohol content of wine, beer, and liquor. Below are typical ranges of alcohol percentages by volume (ABV) of some common types of drinks.
