On average, the human body can dispose of the alcohol in 12 ounces of beer in about one hour.

Quick Scoop

  • A typical 12-ounce beer (around 5% alcohol by volume) is considered one standard drink , and the body usually processes roughly one standard drink per hour.
  • This is only a rough average; factors like body weight, sex, age, food in the stomach, medications, and liver health can make the process slower or faster for each person.
  • Even after an hour, a person might still have measurable alcohol in their system, so this “one hour per drink” idea is best treated as a safety guideline, not a guarantee of being safe to drive or operate machinery.

The “one hour per drink” rule is a helpful rule of thumb, but real life is messier: some people may need significantly longer before their blood alcohol level drops to a safer range.
