☕ Long or short coffee: which contains more caffeine?
How many times do you hear people say at the bar:
“A coffee, please… but make it a long one , I’ve already had too many today!”
The belief is common: a long coffee would be lighter , less strong, more diluted.
But is it really like that?
🔴 Absolutely not.
And now we'll explain why.
🧠 Perception vs. Reality
When we enjoy an espresso, the sense we involve most is taste .
And many misunderstandings are based precisely on this taste perception.
👅 A ristretto coffee has a stronger, more concentrated, dense flavor, so we perceive it as “more full-bodied”.
On the contrary, a long coffee has a more diluted and soft taste, therefore it is considered “lighter”.
But if we look at the technical-chemical process, the opposite happens.
💧 The Extraction: What Really Happens
Making an espresso means passing boiling water under pressure through a dose of ground coffee, enclosed in the filter.
👉 When water passes through dust:
-
dissolves water-soluble compounds (including caffeine)
-
drags oils, sugars, acids, alkaloids
-
releases suspended microparticles
⏱️ And the longer the water stays in contact with the dust, the more substances it can extract .
➡️ Therefore, the longer the coffee is steeped, the greater the amount of caffeine and stimulants contained in the cup.
The flavor may seem “lighter,” but the chemical composition is richer .
⚖️ Ristretto = less volume, less extraction
A ristretto has a shorter extraction: less water passes through the coffee in a shorter time.
The result:
-
it's creamier and more concentrated
-
it has a more intense flavor
-
contains less caffeine than a long espresso
❗ But be careful: ristretto does not mean “weak”, on the contrary.
The perception is stronger, but the content of stimulants is lower than in a long coffee.
✅ Conclusion
🔍 If your goal is to limit your caffeine intake without sacrificing taste, the best choice is:
☕ a nice strong coffee , prepared according to the rules of the art.
Remember:
-
Long coffee = more extraction = more caffeine
-
Short coffee = less extraction = less caffeine
