How much alchol does beer contain?

"Small Beer" used to be consumed by our forefathers in the 16th and 17th century, it was as low as 2%. O'Doul's non-alcoholic beer is 0.5% Most beer ranges from 3.2% (more common in USA) to 5% (more common everywhere else) to 7% (upper end of average). Sam Adams brews a beer that is above 20% alcohol content WITHOUT distillation, which means it's true beer.

So your answer? A very wide range - from 0.5 to 20% and up.

But most beer is between 3 and 7.
