The short answer
A lungo is an espresso pulled long - the same dose producing more liquid, typically around a 1:3 or 1:4 ratio instead of espresso's 1:2. It is a larger drink, and because the later stages of extraction are where bitterness arrives, it usually tastes more bitter rather than milder.

The counter-intuitive part
People assume a lungo is a milder drink because it is more dilute. That is only half the story, and it is the half that misleads.
The extra water is not clean water added to a finished shot - it is water passing through the same puck, continuing to extract. Since the compounds that dissolve last are largely the bitter ones, the additional liquid brings a disproportionate share of them.
So a lungo is more dilute and often more bitter at the same time. If you want a larger, milder drink, adding hot water to a normal espresso - an americano - gets you there without the harshness.
Quick picks
The answer first. Tap any row to jump to the full reasoning for that pick.
1. How you pull one on purpose
Timemore Black Mirror Basic Plus
Mid tier · A rechargeable coffee scale with auto-timing and a flow-rate readout.
A lungo is a ratio, and stopping at the right point requires weighing it.
The line between a lungo and an over-extracted espresso is a number, and without a scale you cannot see where you are on it.
The Black Mirror Basic Plus publishes 2000 g capacity with 0.1 g resolution and a 0.5 g minimum detectable weight, plus automatic timing and a flow-rate readout on the current version.
It measures 152 x 130 x 26 mm, fits most drip trays with a cup on top, and charges over USB-C.
For a long shot the flow-rate display is genuinely useful: it shows the extraction slowing as the puck gives up its resistance, which is the point past which bitterness accumulates fastest.
Specification
- Capacity
- 2000 g
- Resolution
- 0.1 g; minimum detectable 0.5 g
- Timer
- Automatic timing
- Battery
- 1600 mAh, up to 10 hours, USB-C
- Size
- 152 x 130 x 26 mm, about 380 g
What it does well
- Auto-timing and flow rate at a fraction of an Acaia
- USB-C rechargeable rather than a drawer full of coin cells
- Small enough for a drip tray, big enough for a dripper
Where it gives ground
- Not waterproof
- Response is quick but not espresso-instant
- The mirrored top shows every fingerprint
Skip it if
Skip it if you already weigh your shots. Any 0.1 g scale works.
2. The machine that handles long shots best
Breville Dual Boiler
Prosumer tier · A true dual-boiler 58 mm machine: brew and steam at once, PID on the brew boiler.
Temperature stability matters more over a longer extraction, not less.
A longer shot means more water passing through the group, which is exactly when temperature stability is tested.
The Dual Boiler publishes PID control on a dedicated stainless espresso boiler, a separate steam boiler, low-pressure pre-infusion followed by 9 bar extraction, and a 58 mm portafilter taking a 22 g dose.
A machine whose brew temperature drifts during a shot will drift more over a long one, and the later part of a lungo is where drift shows up most clearly as harshness.
The larger 22 g basket also suits long shots, because a bigger dose gives the extra water more coffee to work through.
Specification
- Portafilter
- 58 mm stainless, 22 g dose
- Boilers
- Dual stainless steel, separate espresso and steam
- Control
- PID on the espresso boiler
- Extraction
- Low-pressure pre-infusion, then 9 bar
- Footprint
- 37.9 x 40.3 x 37.1 cm
What it does well
- Brew and steam simultaneously - the actual reason to buy dual boiler
- 58 mm commercial basket size opens the whole accessory market
- PID plus programmable pre-infusion
Where it gives ground
- Big, heavy and power-hungry
- Overkill if you drink one straight espresso a day
- Still needs a grinder at a matching level to be worth it
Skip it if
Skip it if you drink straight espresso at normal ratios. This is a lot of machine for a marginal benefit.
3. If a lungo is what you actually want, consider this
Hario V60 Ceramic Dripper 02
Manual tier · The 60-degree cone dripper that defines modern pour-over.
A lot of people pulling lungos want filter coffee and do not realize it.
This is worth saying plainly: if you are pulling long shots because you want a bigger, lighter coffee, a filter brewer does that job far better.
The V60 is a 60-degree cone with inner spiral ribs and a single large hole, in Arita-yaki ceramic, size 02 at W140 x D120 x H102 mm, brewing 1 to 4 cups.
Filter brewing extracts gently over minutes rather than aggressively over seconds, which is why it produces volume without the bitterness a long espresso accumulates.
It needs a gooseneck kettle, and it is a completely different piece of equipment - but it is the right tool for what a lungo is often being asked to do.
Specification
- Geometry
- 60-degree cone, single large hole
- Ribs
- Inner spiral ribs
- Capacity
- 1-4 cups
- Material
- Arita-yaki ceramic, made in Japan
- Size
- W140 x D120 x H102 mm
What it does well
- The single large hole hands flow control to you rather than the dripper
- Ceramic holds heat far better than plastic
- More published recipes exist for the V60 than for any other brewer
Where it gives ground
- Unforgiving: an uneven pour shows up in the cup
- Ceramic needs preheating and can chip
- Needs a gooseneck kettle to be worth owning
Skip it if
Skip it if you specifically want espresso's crema and body. Filter coffee does not have either.
How to pull a good one
- 1Grind coarser than you would for a normal shot. This lets more water through in the same time and reduces how long the puck is under attack.
- 2Consider a larger dose. More coffee gives the extra water more to work through, which reduces over-extraction per gram.
- 3Stop deliberately. Weigh the yield rather than watching the cup, and stop at your target rather than when it looks right.
- 4Taste and adjust the grind, not the ratio. If it is harsh, coarser. If it is thin and sour, finer.
Lungo and americano are not the same drink
A lungo runs more water through the coffee. An americano adds hot water to a finished espresso. Those produce genuinely different results.
The americano dilutes a balanced extraction, so it is milder without being more bitter. The lungo extracts further, so it is more dilute and often harsher. For most people wanting a larger drink, the americano is the better answer.
Where the lungo genuinely belongs
With coffees that hold up to a long extraction - typically lighter roasts, which are less soluble and give up their bitter compounds more slowly. A light-roast lungo can be genuinely lovely, and a dark-roast one rarely is.
It also has a real place on capsule machines, where the lungo button is often the only route to a drink larger than a shot.
