A lungo is the least understood shot: it is not a diluted espresso but an extended one, and done well it is bright, light, and aromatic instead of bitter.
The longer yield changes the body and finish, not just the volume.The Direct Answer: What a Lungo Is
A lungo ("long" in Italian) is an espresso pulled with more water through the same dose, typically to a ratio of 1:2.5 to 1:3, meaning 18 g of coffee becomes 45-54 g of yield. The extra water extracts more from the coffee, producing a lighter body, more aroma, and a longer finish. Done carelessly it turns bitter; done carefully it is a completely different, enjoyable drink.
Why It Is Easy to Get Wrong
The later part of extraction brings bitterness. When you pull a lungo the same way as a normal espresso, you push through the sweet window into the bitter tail, which is why so many home lungos taste harsh. The fix is not avoiding lungos; it is adjusting for the longer extraction: slightly coarser grind, a slightly cooler temperature, or a bean that can handle the extended pull.
The Ratio and the Recipe
| Style | Dose | Yield | Ratio |
|---|---|---|---|
| Ristretto | 18 g | 18-27 g | 1:1 to 1:1.5 |
| Standard double | 18 g | 36 g | 1:2 |
| Lungo | 18 g | 45-54 g | 1:2.5 to 1:3 |
Start at 1:2.5, taste, then decide if you want to push it further. Weigh the yield so the lungo is intentional instead of accidental.
How to Apply It
Make the extended pull taste clean:
- Dose normally and set the yield target near 45 g for 18 g in.
- Grind slightly coarser than your standard espresso to keep the flow balanced at the longer yield.
- Pull and taste. If bitter, coarsen or shorten the yield.
- If thin and sour, go finer or extend slightly.
Multi-shot machines with programmable pre-infusion and temperature help here, because small adjustments stay repeatable across days.
A longer yield needs its own dial-in, not the same settings as a double.When a Lungo Makes Sense
Choose a lungo when you want a longer, lighter coffee but not a full filter brew, or when a bean has delicate aromatics that a short shot hides. Some roasters roast specifically with a lungo in mind, so check the bag: if the roaster mentions "espresso or lungo," the coffee was designed for this treatment. Dark roasts are usually the worst lungos because the bitter tail arrives early.
Common Mistakes and What to Try Next
If the lungo tastes like espresso with water, you pulled it too short or ground too fine; extend the yield and coarsen to match. If it tastes ashy, lower the temperature or switch beans. If it is watery with no body, your dose is too low for the basket; fix the dose before blaming the style. Each fix is a single variable, tested one pull at a time.

FAQ
Is lungo 2 shots of espresso?
Not exactly. A lungo is one dose of espresso pulled with more water, yielding a larger drink, typically around 1:3. On some machines two lungo portions may be served, but the term describes the longer pull on a single dose, not two separate shots.
Do you add milk to a lungo?
You can, and many people enjoy it with a splash of milk or in a milk drink. Traditionally a lungo is drunk black to taste the extended extraction, but there is no rule against adding milk; let your preference decide.
What is the lungo coffee ratio?
A lungo is usually pulled around 1:2.5 to 1:3, for example 18 g of coffee yielding 45-54 g of liquid. The longer yield extracts more, so the grind or temperature often needs a small adjustment to avoid bitterness.
Is a lungo the same as an espresso?
A lungo is an espresso pulled longer: the same dose, more water, larger yield. The extra water extracts more of the coffee, which changes the flavor profile toward lighter body and more bitterness. It is a longer espresso, not a different drink.
