filtered coffee has had much more time to steep in all the caffeine
True, but I think it’s more complicated than that. Filtered coffee is typically a coarse grind, espresso is fine—and fine grind has a larger surface area to volume ratio, which helps with extraction.
I have also heard that caffeine leaches out fairly quickly, so it gets to be diminishing returns pretty quickly.
Totally, i believe the bean and the burning process also matter in how much caffeine a cup of coffee has in the end. Also i believe espresso coffee is fattier wich influences the flavour and caffeine amount because a filter let’s less particles true or something.
