Coffee guru James Hoffman purchased a shmancy caffeine testing kit to get some real data. Some of the findings confirm info that is anecdotally passed around, other findings, quite the opposite. A surprising bit is that caffeine extraction is separate from coffee extraction as a whole.
Definitely some surprises in this one for me! I suspect this is a topic that I’m not yet done with, so very interested to hear your thoughts or suggestions for future tests!
