Italian concentration
The false impression of espresso = high caffeine seems to have taken root in everyone's mind. In fact, real espresso beans are usually roasted deeply for a long time, and there is not much caffeine left. As for the remaining little caffeine, it must be extracted for a long time to dissolve. As a result, espresso with an extraction time of only 25-30 seconds has a lower content than ordinary coffee.
