And here’s the problem with Wikipedia - while technically darker roasted coffee doesn’t have more caffeine by volume than lighter roasts…technically the way coffee is brewed properly is by weight, and darker grounds are often used for things like espresso, which requires a much finer grind. So the same volume of dark grounds will technically have more coffee grounds than a lighter roast used for drip or pour-over.
Lots of detail is obfuscated when things are summarized. Sometimes those details matter.
Also, it seems a lot if this doesn’t address the facetious or hyperbolic angle of these statements (though several do).
Again, sometimes this change in level (or direction) of focus fundamentally changes what something means.
The databases at my company nearly 30 years ago were staggering at the time. I can only imagine.
