sf_logoThis calculator is not a legal definition or indicator of blood alcohol content. It is intended to be used as an approximate guideline to inform beer drinkers of the estimated potential blood alcohol content range that one might experience after responsibly enjoying the flavor and diversity of beer. It is not intended to estimate the affect of other alcoholic beverages, particularly mixed drinks/cocktails because of the uncertainty in determining an accurate alcohol content of mixed drinks with added liquor/distilled spirits.
