Hmm, I think time frame is at play here--I had forgotten the early modern constraint! Nonetheless this is a great resource for more reading--cheers!

- soundwave106 10y agoYeah... it's a pity (an understandable one in way) that I couldn't find more older more technical brewing books scanned online for quick reference. But at least some resources quote them. There's definitely a fair bit of older brewing books sitting in dusty corners of certain libraries that would be interesting to read. :) This modern printing of a book from 1785 (https://www.amazon.com/Hydrometrical-observations-experiments-brewery-Baverstock/dp/1140735802 https://www.amazon.com/Hydrometrical-observations-experiment...) for instance would've been interesting to view to get a perspective from a century earlier (at least for British porter). Unfortunately I can't find a digitized version online, but querying on that book led to this link, (https://books.google.com/books?id=GSTnBAAAQBAJ&pg=PT24&lpg=PT24&dq=Hydrometrical+Observations+and+Experiments+in+the+Brewery,+1785+First+Edition&source=bl&ots=Ag9jcqkL5p&sig=TOvFkq69We5ncQH3mXCQ2z2poLQ&hl=en&sa=X&ved=0ahUKEwjy5vi_me_RAhVCb5oKHX6FCckQ6AEILTAE#v=onepage&q=Hydrometrical%20Observations%20and%20Experiments%20in%20the%20Brewery%2C%201785%20First%20Edition&f=false https://books.google.com/books?id=GSTnBAAAQBAJ&pg=PT24&lpg=P...) does quote a 1784 porter at OG 1.071 FG 1.018 (about 7%). The full reference would probably be more helpful to determine a better picture of the historical range back then. I believe the hydrometer only came into use in brewing science in the mid to late 1700s; before then, data definitely would've been a lot sketchier.
