A lungo is an espresso pulled long: the same dose of ground coffee, but two to three times the water run through it, taking twice the time. The result is a bigger, more bitter, less syrupy cup. Espresso is 1 to 1.5 oz of concentration; a lungo stretches that shot to 2 to 4 oz by continuing the extraction. It is not an americano, which adds water after the shot; a lungo pushes all its water through the puck, extracting compounds a standard shot deliberately leaves behind.
Side by side
| Espresso | Lungo | Americano | |
|---|---|---|---|
| Water through the puck | ~2x the coffee weight | 2 to 3x an espresso's water | Espresso's amount only |
| Extra water added after | None | None | 4 to 10 oz hot water |
| Size | 1 to 1.5 oz | 2 to 4 oz | 8 to 12 oz |
| Taste | Dense, balanced | Bigger, more bitter, more roast | Espresso flavor, coffee strength |
| Caffeine | ~63mg per shot (USDA) | Slightly more than the same shot | Same as its shots |
Why the lungo tastes harsher
Extraction is sequential: acids and sugars come out of the grounds early, bitter compounds late. A barista cuts a standard shot before most of the late bitterness arrives. A lungo keeps pulling into that zone on purpose, which is why it reads roastier and more astringent. More water also means slightly more caffeine than the same shot cut short, since extraction time went up, though the difference is modest next to just ordering a double.
Where you actually meet lungos
Mostly on pod machines: Nespresso builds entire capsule lines around the lungo size, and the "which button do I press" confusion is half the search volume for this term. On Vertuo machines the barcode sets the size automatically; on Original machines the lungo button simply runs more water through the same capsule, with exactly the flavor consequences above. Our Nespresso machine guide covers the lineup, and the drink decoder places the lungo among its relatives.

FAQ
Is a lungo stronger than an espresso? It has slightly more caffeine but tastes weaker per sip: the same coffee stretched over more water, with extra bitterness from the longer pull.
Is a lungo the same as an americano? No. A lungo runs all its water through the coffee; an americano dilutes a finished shot with hot water, keeping the shot's balanced flavor at drinking strength.
What is a lungo on Nespresso? The larger shot size, about 3.7 oz on Original-line machines: the same capsule with more water pushed through it.
