how much does the alcohol content drop an hour
BAC goes down at a slow and predictable rate. This is because your liver can only metabolize a predictable blood alcohol concentration per hour. The normal body will metabolize between .015 percent and .020 percent BAC per hour. We use a conservative .016 percent BAC per hour in the following charts. Some heavy drinkers may eliminate alcohol at a slightly higher rate and certain physical conditions may cause some people to metabolize alcohol at a slower rate.
