You can’t argue that driving a vehicle after drinking is a good thing to do. This takes on a whole new meaning though with the rise of craft brewing.
Blood alcohol level or content (BAC) is defined as the percentage of alcohol in a person’s blood. A BAC of 0.10 means that 0.10% (one tenth of one percent) of a person’s blood is made up of alcohol. In the United States, the legal limit is .08.
According to the Center for Disease Control (CDC ), a standard beer is 12 oz. and contains .6 oz. of alcohol assuming the beer is 5% alcohol. I weigh 120 lbs, which means I can drink 2 beers in an hour before reaching the US legal limit.
However, as a craft beer lover, I typically drink beers around 7.5% alcohol and I am often drinking pints (16 oz.) instead of bottles (12 oz.). So the math is totally different. I can only have 1 beer before reaching the US legal limit.
The National Transportation Safety Bureau is heading an effort to get the BAC limit lowered to .05 from .08. If that happens, we’ll probably start seeing a lot more session beers produced by craft breweries.
