There’s coffee snob sites out there that will go into incredibly gory detail of roast levels and brewing mechanism and caffeine measurement. Like this one. And a myriad of others. (I just took the first hit off a search here, but the search terms were “detailed caffeine breakdown in coffee by varietal, roast, and brewing mechanism”. There were many, many, many more hits if that one’s not suitable. Like this one.)
I checked those out and the information is just vague.
They will say things like a 8 oz cup of coffee has 90 mg of caffeine. They won’t tell you how much ground coffee was used to achieve that.
They use weasel statements like espresso will have more, longer brew times will have more. Vague descriptions like “a typical 12 oz coffee will have 95 mg of caffeine, depending on how much coffee grounds were used”
