I drink two strong cups in the morning...and it’s enough to make me jittery all day.
I don’t know how anyone could drink 4 strong cups every day.
Maybe they’re talking about those little 6oz cups? They’re pretty common in Europe...not like the mugs we drink here.
They are talking about espresso — one small cup has more caffeine, than several cups of American coffee.
They are finally figuring out that coffee and chocolate are good for you, even eggs, after many years of telling you the opposite.
Everything in moderation is probably fine. People are different from each other, so there is no one solution for all.
Israeli (or Arab) coffee is strong like espresso and you don’t need (or want) a venti sized mug.
I like my French pressed Peets dark roast.
