Lungo Coffee: Recipe, Ratio, Caffeine, Calories and Taste

That recipe is a practical house baseline, not a universal Italian cafe standard. Taste the 54 g cup first. Extend toward 57-60 g only when the coffee stays balanced, because simply running the shot longer can introduce a dry, hollow, or bitter finish.

Lungo at a Glance

The key measurement is beverage mass. Grams and milliliters are not interchangeable, and crema can make volume unusually variable. Weighing the finished drink gives you a more repeatable recipe than stopping when the cup looks full.

What Is Lungo Coffee?

The Italian word lungo means long. In coffee, it describes an espresso prepared with a longer yield: more water travels through the puck while the machine remains under pressure. It is still espresso-based, but the larger output changes concentration, body, extraction, and the balance of flavors in the cup.

That water path is the defining practical distinction. A standard espresso uses a shorter output from a similar dose. An Americano begins with espresso and receives separate hot water after extraction. A lungo does not become longer through post-brew dilution; its additional brewing water passes through the grounds.

There is no single worldwide lungo size. Espresso recipes vary by cafe, basket, coffee, and equipment, while capsule systems use their own programmed volumes. The Italian Espresso Institute specifies approximately 25 ml for its certified Italian espresso reference, but that certification does not establish one universal lungo recipe.

For a modern portafilter recipe, brew ratio is more useful than a nominal milliliter target. La Marzocco's espresso-ratio guidance describes longer espresso styles around the 1:3 to 1:4 range while emphasizing that ratio is the relationship between dry coffee mass and liquid espresso mass.

What Does a Lungo Taste Like?

A well-balanced lungo keeps recognizable espresso aroma while feeling less concentrated and less dense. Compared with a standard shot, it usually has:

• lighter body and a more open texture
• a longer finish
• less flavor concentration per sip
• more obvious roast, nut, cocoa, or dry spice notes in some coffees
• a greater risk of bitterness or astringency when the yield is pushed too far

Longer does not automatically mean bitter, and crema thickness does not prove that the shot is good. Coffee, roast, grind, water, temperature, flow, and yield all influence the result. A pale final stream may help diagnose a shot, but taste should decide whether you keep or shorten the recipe.

The most useful tasting sequence is to try the 54 g target after it cools for a moment. If it is sweet, clear, and still structured, test 57 g on the next shot. If that remains balanced, 60 g may work. Stop extending when the finish becomes drying, papery, hollow, or sharply bitter.

Lungo Ratio and Yield

Use the formula:

Finished beverage mass = dry coffee dose x brew ratio

An 18 g dose at 1:3 produces 54 g of lungo. The same dose at 1:3.3 produces about 60 g, while 1:4 produces 72 g. The numbers define the output, not whether that output tastes good.

Start at 1:3 instead of jumping directly to 1:4. A longer numerical ratio increases extraction opportunity, but coffee-specific flavor still determines the useful stopping point.

How to Make a Lungo

This recipe uses an espresso machine, a scale, and a conventional portafilter. If your machine uses capsules or has a fixed Lungo button, see the capsule section before applying these measurements.

Recipe Snapshot

Ingredients

• 18 g fresh coffee, ground fine for espresso
• Filtered water, as required by the machine

Method

1. Heat the equipment. Bring the espresso machine fully to temperature and preheat a 90-120 ml cup.
2. Dose and grind. Weigh 18 g coffee and grind it fine for espresso. Begin near your working espresso setting rather than making a large grind change immediately.
3. Prepare the puck. Distribute the grounds evenly, tamp level, and lock the portafilter into the machine.
4. Start by weight. Place the cup and a scale under the group head, tare the scale, and begin the extraction.
5. Stop at 54 g. End the shot at 54 g finished beverage for a 1:3 brew ratio. Record the time, but do not chase a time target at the expense of taste.
6. Taste and adjust. Let the drink cool slightly. Change the yield or grind one variable at a time for the next shot.

How to Dial in a Lungo

Keep dose stable while you adjust grind and yield. That makes each comparison easier to interpret.

Shot time helps reveal changes in resistance. A 54 g lungo may fall somewhere around 25-40 seconds on many setups, but time alone does not define the drink. A faster balanced shot is preferable to a slower shot made bitter merely to satisfy the clock.

The Specialty Coffee Association's espresso survey illustrates why measured recipes matter: contemporary baristas use varied doses and yields, and most surveyed respondents weighed beverage output. Record dose, yield, and time, then let taste choose the next adjustment.

Lungo vs. Espresso

Lungo and espresso use the same pressure-brewing method, but their yield and concentration differ.

A lungo is not simply a weak espresso. Its longer extraction changes which soluble compounds enter the drink and how concentrated they are. Research comparing espresso methods has found that lungo-style preparations can be less concentrated while delivering more extracted material in the complete serving. The exact result still depends on coffee, grind, dose, water, and recipe.

Lungo vs. Americano

An Americano is diluted after the espresso has been extracted. A lungo is lengthened during extraction.

This distinction matters when you want more volume. If a 1:3 lungo already tastes dry, do not force it toward a mug-sized yield. Pull a balanced shot and add hot water instead.

Lungo, Doppio, Ristretto and Similar Drinks

These names do not all describe the same variable:

• Lungo describes a longer extraction yield relative to the dose.
• Doppio describes serving count: a double espresso, not a particular brew ratio.
• Ristretto describes a shorter yield relative to the dose.
• Americano describes espresso diluted with hot water after extraction.
• Caffe crema is generally longer and more mug-like, often using a coarser grind and a much larger output than a lungo.
• Long black uses espresso with hot water, traditionally placing the water in the cup first.

Keeping serving count, extraction yield, and added water separate prevents common ordering and recipe confusion. A doppio lungo, for example, can be both a double serving and a longer-yield extraction.

Is Lungo the Same as Cafe Allonge?

The names overlap, but context matters. Cafe allonge means lengthened coffee in French and can refer to a long espresso-style drink in French-speaking cafes, including Quebec. House recipes may use a longer pull, added water, or local serving conventions.

For that reason, this page uses lungo for the portafilter recipe defined by beverage yield. The separate Cafe Allonge guide covers French-language naming and regional context. Do not assume that every menu uses the two terms as exact technical synonyms.

How Much Caffeine Is in a Lungo?

There is no trustworthy universal caffeine number for a portafilter lungo. Caffeine depends on the beans, species, dose, grind, extraction, and recipe. Finished beverage weight and visible cup volume cannot calculate it.

With the same dry dose, a longer extraction may collect similar or somewhat more total caffeine than a shorter shot while producing a less concentrated drink. A 2013 study comparing espresso preparation methods found higher per-cup extraction in lungo preparations but lower concentration than shorter espresso. That direction is useful; it is not a promise that every 18 g lungo contains one fixed amount.

The research literature also shows that brew ratio, grind, temperature, and flow alter extraction. A 2023 espresso study found beverage mass to be a major factor in total extracted material, reinforcing why yield should be recorded. It still does not let us infer caffeine precisely from the number on the scale.

If an exact caffeine figure matters for health or medication, use a product with manufacturer data or seek professional medical guidance. The house portafilter recipe has not been laboratory-tested.

How Many Calories Are in a Lungo?

Plain lungo is very low in calories. Applying the USDA restaurant-prepared espresso reference of approximately 9 calories per 100 g to a 54 g drink gives 4.86 calories, rounded to approximately 5 calories.

These are ingredient-based estimates, not laboratory measurements. Coffee solids vary, and milk or sweetener labels should be used when an exact total matters.

What Does Lungo Mean on a Nespresso Machine?

Nespresso Original uses Lungo as a programmed capsule-system serving convention. The company's support material lists a 110 ml Lungo setting and a published caffeine range of approximately 70-110 mg per Original Lungo serving.

That information is specific to Nespresso Original capsules and their recommended volume. It is not the caffeine value or recipe for an 18 g portafilter lungo. Capsule fill, coffee, machine programming, and extraction system differ.

If the 110 ml capsule drink tastes thin or bitter, use the capsule maker's instructions first. Reprogramming a smaller output may suit your taste, but the 18 g to 54 g recipe on this page should not be copied directly onto a capsule machine.

Can You Make Lungo Without an Espresso Machine?

Not exactly. A lungo is defined by espresso-style pressure extraction with more brewing water passing through the puck. A moka pot, AeroPress, or strong filter coffee can produce a longer black coffee with some similar intensity, but it is not technically a lungo.

Without an espresso machine, make the method you have well and name it accurately. If you want a longer drink from concentrated coffee, brew the concentrate to a balanced endpoint and dilute it afterward rather than forcing excess water through unsuitable grounds.

Best Coffee for Lungo

Start with a coffee that already tastes balanced as espresso. Medium and medium-light roasts often preserve sweetness and clarity as the yield increases. Dark roasts can work, but their roast bitterness may become more obvious during the longer extraction.

Do not choose only by roast label. Bean density, freshness, grinder quality, and water chemistry can matter more. Test the same coffee at 1:2 and 1:3, let both cups cool slightly, and compare sweetness, body, acidity, and finish.

How to Pronounce and Order Lungo

In Italian, lungo is approximately pronounced LOON-go. On a menu, ask for "a lungo" or "an espresso lungo." If the cafe uses capsule-style or local volume conventions, ask whether its lungo is a longer extraction or an espresso diluted after brewing.

That short clarification is especially useful outside Italy, where long espresso, long black, Americano, and allonge can be interpreted differently.

Common Questions

Bottom Line

A lungo is a longer espresso extraction, not an espresso topped up with hot water. Begin with 18 g of coffee and 54 g of finished beverage, taste the 1:3 cup, and extend only while sweetness and structure remain. Weigh the output, treat shot time as a diagnostic, and keep capsule-system volumes separate from portafilter ratios.
