Coffee fact: the darker the roast, the less caffeine the coffee has.
This is why "breakfast blend" tends to be a lighter roast. The roasting denatures the caffeine rendering it ineffective. Or, less effective.
If you want really strong coffee, go with a blond roast. The flavor sucks boogers, but it'll have the biggest kick of caffeine in it. French roast,
as you likely guessed, has the least. Even if it tastes like it'll wake up a den of bears, it just lacks the chemical punch needed.
You can get fortified coffee. That is, coffee that has caffeine added. Tastes like the south end of a north bound mule....but it exists.
