What is a lungo? Espresso extraction, size, and taste
Jack Donnell
At a glance
A lungo sends more brewing water through the grounds. Compare extraction, drink size, and dilution before choosing your next coffee.
A lungo is an espresso-style coffee made with a longer extraction and a larger beverage yield than the brewer's usual espresso. The additional water passes through the coffee grounds. An Americano takes a different route: water is added to an already brewed espresso.
The distinction explains why two similarly sized cups can taste different. Extraction changes what enters the cup; dilution changes the concentration of coffee that has already been extracted.
Lungo, espresso, and Americano compared
| Coffee | Where the water goes | Main distinction |
|---|---|---|
| Espresso | Through the grounds under pressure | The brewer's standard shot recipe |
| Lungo | More water through the grounds for a larger shot | A longer extraction |
| Americano | Separate water added to espresso | Dilution after brewing |
For the dilution method, read what an Americano is. Choosing a larger mug alone does not turn espresso into a lungo.
How big is a lungo?
There is no single cup size shared by every machine and cafe. For one specific reference, Nespresso's Momento brewing guide labels its lungo size as 3.75 US fluid ounces. That is a setting for that system, not a rule for every espresso machine.
On a manual machine, write down the dry coffee dose and the finished shot weight. For example, comparing an 18-gram dose brewed to 36 grams with the same dose brewed to 54 grams shows what a larger yield means. These are arithmetic examples, not a prescription for every bean.
For capsule equipment, follow the intended format for the capsule and machine. A label such as Gran Lungo may name a separate programmed drink; check that system's instructions rather than assuming the name refers to the same manual recipe.
What does a lungo taste like?
A longer shot changes both concentration and extraction. It can reveal a different flavor balance from a shorter shot made with the same beans. Avoid assuming that more liquid automatically means a milder, sweeter, or better cup.
To compare methods, keep the beans and dose consistent. Taste the standard espresso first, then the larger extraction. On another trial, dilute the standard espresso to the same finished weight. The comparison helps separate the flavor of additional extraction from the effect of extra water.
Common lungo questions
Is a lungo a double espresso?
No. Double commonly describes a shot made with a larger coffee dose. Lungo describes a longer beverage yield. Ask the cafe which dose and recipe it uses.
Can I make a lungo by adding hot water?
Adding water after extraction makes an Americano-style drink. For a lungo, the extra brewing water passes through the grounds.
Does lungo always contain more caffeine?
The name does not specify a measured caffeine amount. Coffee dose, beans, and preparation vary, so do not infer a precise figure from cup size.
Compare the longer yield with a shorter ristretto shot. The difference is the extraction recipe; our Americano guide explains water added after the shot is brewed.
