This was my understanding too, but the article in the first footnote uses some much larger values for alcohol content. It generally seems well sourced but these numbers are all over the place as if the author first got the numbers and then randomly placed the decimal point and termed some of them 'percentages'. > Wine is taken to be 0.12 alcohol, the same number is used in modern estimates of alcohol consumption. The amount of alcohol consumed by drinking historical beer brews is between 0.62 to 0.107, the % of alcohol in “small beer” is taken to be around 0.05 and the % in “strong beer” is taken to be around 0.135,
