On average, how long does it take for 12 ounces of beer to be cleared from your body?

The average time it takes for 12 ounces of beer to be cleared from the body is typically around one hour. This estimate is based on the fact that the body generally metabolizes alcohol at a rate of about one standard drink per hour. A standard drink is defined as containing approximately 14 grams of pure alcohol, which is roughly the amount found in a 12-ounce serving of beer with an alcohol by volume (ABV) of around 5%.

Factors such as body weight, metabolism, age, and overall health can influence the rate at which alcohol is eliminated from the system; however, the one-hour rule serves as a good general guideline for most individuals. This knowledge is crucial for making safe decisions about driving and other activities that require full cognitive and motor skills after consuming alcohol.
