How to Make A Lungo Coffee: Step-by-Step Guide

Quick Answer

• Use more water than for an espresso, typically a 1:3 to 1:5 ratio of coffee to water.
• Aim for a finer grind, similar to espresso but maybe a touch coarser.
• Pull the shot longer, around 45-60 seconds for a standard double.
• Watch for the color change; stop just before it gets too pale and watery.
• Don’t over-extract, or you’ll get bitter, unpleasant flavors.
• A good lungo should be strong but smooth, with a pleasant aftertaste.

Who This Is For

• Coffee drinkers who want a longer, less intense espresso-style drink.
• Home baristas looking to expand their espresso repertoire beyond a standard shot.
• Anyone who finds a straight espresso a bit too concentrated for their liking.

What to Check First

Brewer Type and Filter Type

This guide assumes you’re working with an espresso machine. Other methods won’t produce a true lungo. Make sure your machine is compatible and you’re using the correct portafilter basket. If you’re using a pod machine, check if it offers a lungo option.

Water Quality and Temperature

Good coffee starts with good water. Filtered water is your best bet. Tap water can have off-flavors that mess with your brew. Water temperature is critical for espresso. For a lungo, it’s usually around 195-205°F (90-96°C). Your machine should handle this, but if it’s acting up, check the manual.

Grind Size and Coffee Freshness

This is huge. For a lungo, you want a grind that’s finer than drip coffee but potentially a touch coarser than for a super-short espresso. Think granulated sugar, maybe a bit finer. Freshly roasted beans are key. Grind them right before you brew. Stale coffee is a one-way ticket to a bad cup, no matter how you brew it.

Coffee-to-Water Ratio

This is where the lungo differs. While a standard espresso might be 1:2, a lungo often uses 1:3 or even 1:5. So, for a double shot (say, 18 grams of coffee), you’re looking at 54-90 ml of liquid. Experiment to find what you like. Too much water, and it gets weak. Too little, and it’s just a long espresso that’s over-extracted.

Cleanliness/Descale Status

Your machine needs to be clean. Old coffee oils go rancid and taste awful. Regularly clean your portafilter, basket, and group head. Descaling is also important. Mineral buildup can affect temperature and flow, which you absolutely do not want when pulling a delicate lungo. Check your machine’s manual for cleaning and descaling schedules.

Step-by-Step: How to Make a Lungo Coffee

1. Grind Your Beans: Grind your fresh, whole coffee beans to a fine consistency, similar to espresso but perhaps a hair coarser.

• Good looks like: Uniformly sized particles, like fine sand or slightly coarser.
• Common mistake: Grinding too coarse, which leads to weak, watery coffee. Grind too fine, and you’ll choke the machine.

2. Dose Your Portafilter: Place the correct amount of ground coffee into your portafilter basket. For a double shot, this is typically 14-20 grams.

• Good looks like: The grounds fill the basket evenly, without being too compressed or too loose.
• Common mistake: Inconsistent dosing. Use a scale for accuracy.

3. Distribute the Grounds: Gently tap the portafilter to settle the grounds. Use a distribution tool or your finger to level the surface.

• Good looks like: An even bed of coffee with no high spots or gaps.
• Common mistake: Tamping unevenly or not distributing at all. This creates channeling.

4. Tamp the Coffee: Apply firm, even pressure to tamp the coffee grounds. Aim for a level puck.

• Good looks like: A smooth, flat surface on top of the coffee puck.
• Common mistake: Tamping too hard or too soft, or at an angle. This affects extraction.

5. Lock in the Portafilter: Secure the portafilter into the group head of your espresso machine.

• Good looks like: A snug fit with no leaks.
• Common mistake: Not locking it in fully, leading to grounds blowing out.

6. Start the Brew: Place your cup(s) under the spouts and start the extraction.

• Good looks like: A steady stream of coffee, starting dark and gradually lightening.
• Common mistake: Starting the brew too soon or too late.

7. Monitor the Flow and Color: Watch the stream of coffee. It should flow like warm honey. As it progresses, the color will change from dark brown to a lighter caramel, then to a pale, watery blonde.

• Good looks like: A consistent, controlled flow that gradually lightens.
• Common mistake: Letting it run too long until it becomes very pale and thin.

8. Stop the Extraction: This is the key to a lungo. You’ll want to let it run longer than a standard espresso, typically 45-60 seconds, or until the stream starts to turn noticeably blonde and watery. Stop before it gets too pale.

• Good looks like: A rich, amber liquid that has a pleasant aroma.
• Common mistake: Letting it run until it’s just watery brown, which extracts bitter compounds.

9. Serve Immediately: A lungo is best enjoyed right away.

• Good looks like: A warm, aromatic cup of coffee.
• Common mistake: Letting it sit and cool down.

Common Mistakes (and What Happens If You Ignore Them)

Mistake	What It Causes	Fix
Grind too coarse	Under-extracted, sour, weak coffee	Adjust grinder finer; aim for a 45-60 second extraction time.
Grind too fine	Over-extracted, bitter, choked machine	Adjust grinder coarser; ensure proper tamping and distribution.
Uneven tamping	Channeling, uneven extraction, sour/bitter	Tamp level and with consistent pressure; distribute grounds evenly.
Dosing inconsistently	Variable shot times, inconsistent flavor	Use a scale to weigh your coffee grounds for every shot.
Using stale coffee	Flat, dull, no aroma, unpleasant taste	Use freshly roasted beans and grind just before brewing.
Water too hot/cold	Sour (too cool) or bitter (too hot)	Ensure your machine is at the correct temperature (195-205°F).
Over-extraction (too long)	Bitter, astringent, watery taste	Stop the shot when the color starts to turn pale blonde.
Under-extraction (too short)	Sour, acidic, lacks body	Extend the brew time; check grind size and tamping.
Dirty machine	Rancid oils, off-flavors, poor extraction	Clean your portafilter, basket, and group head regularly.
Using poor water quality	Off-flavors, mineral buildup	Use filtered water for brewing and descaling.

Decision Rules

• If the coffee tastes sour, then the grind is likely too coarse or the extraction time was too short, because under-extraction leads to acidity.
• If the coffee tastes bitter, then the grind is likely too fine or the extraction time was too long, because over-extraction pulls out bitter compounds.
• If the shot runs too fast, then the grind is too coarse or the tamp was too light, because less resistance means faster flow.
• If the shot chokes the machine (runs too slow or stops), then the grind is too fine or the tamp was too hard, because too much resistance stops the flow.
• If there’s visible channeling (spurts of coffee), then the distribution or tamping was uneven, because water finds the path of least resistance.
• If the coffee tastes weak and watery, then you might be using too much water for the amount of coffee, or the grind is too coarse.
• If the crema is thin and dissipates quickly, then the coffee might be stale or the extraction parameters are off.
• If the coffee has a burnt taste, then the water temperature might be too high, or the extraction went on for way too long.
• If you’re unsure about your machine’s temperature, then consult your owner’s manual, because precise temperature is key to good espresso.
• If your lungo lacks sweetness, then try adjusting your grind size slightly finer and aim for that perfect extraction window.

FAQ

What’s the difference between an espresso and a lungo?

A lungo uses more water and a longer extraction time than a standard espresso. This results in a larger volume of coffee with a less intense, though potentially more bitter if over-extracted, flavor.

Can I make a lungo with a drip coffee maker?

No, a true lungo is an espresso-based drink made with high pressure from an espresso machine. Drip coffee makers use gravity and a different grind size, so you won’t achieve the same result.

How much coffee should I use for a lungo?

The amount of coffee grounds is typically the same as for a standard espresso shot (e.g., 14-20 grams for a double). The difference is in the amount of water used and the extraction time.

How long should a lungo shot take?

A good lungo shot typically takes between 45 and 60 seconds to extract. This is significantly longer than a standard espresso shot, which is usually around 25-30 seconds.

What if my lungo tastes watery?

This could mean your grind is too coarse, your tamp was too light, or you let too much water through. Try grinding finer or stopping the extraction a bit sooner.

Is a lungo healthier than an espresso?

Both are relatively low in calories. A lungo will have more caffeine by volume simply because there’s more liquid, but the caffeine extraction per gram of coffee is similar.

How do I know when to stop the lungo extraction?

Watch the color of the stream. It starts dark, then turns to a caramel, and finally a pale blonde. Stop the shot just as it starts to become noticeably blonde and watery, before it turns greyish.

Can I add milk to a lungo?

Absolutely! Many people enjoy a lungo with steamed milk, creating drinks like a smaller latte or a watered-down cappuccino.
