while we all read about the caffeine content in drinks (obviously coffee included) can any one tell me how they test the quantity? I assume makers of caffeine / sugar drinks know the contant because they add it in.
It seems that most coffee caffeine content quotes can be sourced to a paper from the 70s (from a time and country that considered simmering for hours good coffee).
I would love to have a pile of espresso shots tested from different roast depths and origins to get an idea of actual caffeine content.
So... where do we book a day of caffeine tests?
