Frequently Asked Questions
What is a standard drink?
In the US, one standard drink contains 0.6 fluid ounces (14 grams) of pure alcohol. This equals: 12 oz of regular beer (5%), 5 oz of wine (12%), or 1.5 oz of distilled spirits (40%). Many cocktails and craft beers contain more than one standard drink worth of alcohol.
How fast does the body process alcohol?
The liver metabolizes alcohol at roughly 0.015% BAC per hour on average. No amount of coffee, exercise, food, or cold showers speeds this up — only time works. Someone at 0.08% BAC needs approximately 5+ hours to reach 0.00%. Food before drinking slows alcohol absorption but doesn't reduce total alcohol processed.
