Now according to figures from the National Institute on Alcohol Abuse and Alcoholism, if you look at ABV data, a standard drink works out at about 14 grams of ethanol. Of course, the amount of ethanol can differ greatly depending on whether you're drinking beer, wine, or spirits and that's mainly down to the way it's made and therefore how it ends up in your glass. Industrial usage often applies to grade denatured ethanol Alabama, while beverage alcohol must remain undenatured under strict rules. Variation in ethanol density across drink types requires comparison of ABV values and their influence on the human system.
