For the TL:DW crowd
Espresso 110mg per 36g
Pour Over 170mg per 300g
Instant (if following instructions) is about half of pour over
Darker roast = more caffeine
Caffeine increases with brew time.
Caffeine does not increase with steep time.
This is interesting because, I've always heard things like "contrary to popular belief, lighter roasts contain more caffeine because darker roasting destroys/removes caffeine"

TL:DW - the theory James puts forth is that dark roast coffee has more surface area, so even though there's less caffeine in it what is there gets extracted more easily.

Really? Well I guess I'm the weird one then. It seems much more natural to just get a feel for how much coffee you want and what that looks like in a vessel.

Popular belief around food science topics is almost always founded in nothing. Until someone actually conducts somewhat serious testing, it’s not to be relied on.

Yes, I agree. But what's interesting is the idea I held was always framed as "contrary to popular belief" but it appears the popular belief may in fact be true (darker roast coffee ultimately ends up with more caffeine than light roast). I think the issue is that incomplete data leads to incorrect, albeit well-intentioned, conclusions.
The misinformation surrounding this seems to come from the nuance involved- an article may recommend lighter coffee beans based on the fact that lighter coffee beans contain more caffeine, not realizing the end result has less caffeine potentially because of things like surface area.

Everyone I know who has a single cup brewer uses a scale, including myself - I don’t think it’s as common as you think it is to measure in volume…

It is going to take me a while to process the light vs dark roast finding. I hope someone replicates this study!
