Overview
About Espresso
Espresso is the most concentrated way to drink caffeine: around 2 mg per ml, roughly five times the caffeine density of drip coffee, packed into a 30 ml shot.
A single shot runs about 60 to 80 mg and hits fast, which is why espresso and doppio-based drinks can trigger jitters, a racing heart, reflux or poor sleep even though the cup looks tiny. Coffee is also a mild histamine liberator, so a strong espresso can add to a histamine load.

FAQ
Common questions about Espresso
Does espresso have more caffeine than regular coffee?
Per ml, yes, espresso is far more concentrated, roughly five times a drip coffee. But a single shot is only about 60 to 80 mg, which is less total caffeine than a large mug of drip coffee at 95 to 120 mg or more, because the serving is so small. Order a double or several shots and it quickly overtakes a mug.
Why does espresso make me jittery so fast?
A shot concentrates 60 to 80 mg of caffeine into a tiny volume you drink in seconds, so it is absorbed quickly and the blood-caffeine spike is sharper than sipping a large mug over half an hour. That fast spike is what many people feel as sudden jitters.
Is espresso ok on a low-histamine diet?
Coffee is a mild histamine liberator, so a strong espresso can contribute to a histamine load. Some people tolerate a single shot better than a large brewed volume; if you are sensitive, decaf, oolong tea or a herbal tea are gentler choices.
