The healthy human liver eliminates alcohol at a roughly constant average rate of approximately:
Explanation
The liver oxidizes alcohol via alcohol dehydrogenase at a roughly fixed rate of about 0.015% BAC per hour for the average adult, equivalent to about one standard drink per hour. Body size, sex, food, and genetics cause some variation, but nothing the customer does — coffee, cold shower, fresh air, exercise, food after drinking — speeds liver metabolism. A patron at 0.10% BAC who stops drinking will need roughly 6-7 hours to fall to zero.
