Testing the actual caffeine content of prepared coffee has some surprising results.

Video:

Pour over brewing Vs Expresso

Pour over 170mg

Expresso 110mg

Extending the extraction time appears to be a big factor in the amount of caffeine extracted.

Instant Coffee 40 - 60 mg

Roast level

Light 67.5mg

Dark 72mg

it may be that the dark roasted coffee is less dense and allows better extraction of caffeine.

Was that popular belief determined by duhmacracy?

Anyway, extending the extraction time of the Espresso will greatly increase the caffeine extracted. It's SCIENCE!

What about pressed coffee? Is that considered pour over?

I use the Aeropress every morning. Wife likes Taster's Choice instant.

Those are things he plans to test, but in the video he postulates, in so many words, extending the extraction time appears to be a big factor in the amount of caffeine extracted, probably a key factor.

so the secret to maximum concentration of caffeine in coffee is slow drip?

has he tried running the brewed coffee through the used grounds a second time and then measuring caffeine content?

whatever...even though caffeine is part of the reason I enjoy coffee, it isn't the only thing...taste matters...
