Hah fair enough. Whole bunch is usually is 2 pots of 4 grams, 3 infusions each. But some people (like my wife) can guzzle filter coffee (much more total caffeine than my single shot) all day and have no trouble getting to sleep. Which makes me jealous. It’s all relative I guess
espresso + a whole bunch of sencha = calm + still able to fall asleep ==/==> "sensitive to caffeine", at least to my eyes!
