Beer  how many grams of alcohol?
I'm not 100% on how to calculate the total grams of alcohol in a beer.
I would make an assumption that if a beer is 3.9% alcohol by volume, then take the total weight in grams of the beer, and multiply by 3.9% to determine the grams. Is this correct?
The low calorie/carb beers don't list that on their nutrition label.
