Ristretto vs Lungo vs Espresso: Shot Sizes Explained

Ristretto vs lungo comes down to one variable: how much water you push through the same puck of coffee. A ristretto is a short, restricted shot with less water, so it is thick, sweet and intense. A lungo is a long shot with more water, so it is lighter in body, more bitter and more like a strong black coffee. The normal espresso, sometimes called a normale, sits in the middle.

Because they share the same dose and the same grinder, these three shots are a great way to understand extraction. Here is how they compare in ratios, time, taste and caffeine, and how to pull each one at home.

Key takeaways

• Ristretto uses roughly half the water of a normal espresso; lungo uses roughly double or more.
• Modern specialty recipes by weight are commonly about 1:1 to 1:1.5 for ristretto, 1:2 to 1:2.5 for espresso and 1:3 to 1:4 for lungo.
• Shorter shots taste sweeter and thicker; longer shots taste thinner, clearer and often more bitter.
• A lungo is not an Americano: the extra water goes through the coffee, not added afterward.
• Caffeine changes less than you might think, because the dose stays the same.

The basics: same coffee, different water

In Italian, ristretto means restricted or shortened, and lungo means long. Both start from the same dose of finely ground coffee in the same portafilter basket as a normal espresso. What changes is when you stop the shot.

As water flows through the coffee, it extracts different compounds at different speeds. Acids and many aromatic compounds dissolve early, sugars and body-building compounds follow, and more bitter, drying compounds keep coming as the shot runs on. Stop early and you capture mostly the first group; keep going and you collect more of the later ones, along with more water to dilute everything.

A note on traditional definitions

The Italian Espresso National Institute (INEI) defines its certified espresso by volume: about 7 g of coffee, water at about 88°C, 9 bar of pressure and a 25 ml cup in around 25 seconds. Most specialty cafes and home baristas now measure by weight with a scale instead, which is more precise because crema makes volume hard to judge. That is why you will see slightly different numbers depending on the source.

Ratios, volumes and times

Here are typical modern starting points. The ratio is grams of dry coffee to grams of liquid espresso in the cup.

Volumes are approximate because crema takes up space and varies with roast and freshness. If you can, use a small scale under your cup: it makes your results repeatable.

Lungo vs Americano vs long black

• Lungo: more water runs through the coffee during the shot.
• Americano: a normal espresso topped with hot water afterward.
• Long black: a normal espresso poured on top of hot water.

Because the extra lungo water passes through the grounds, it extracts more compounds, including bitter ones. An Americano simply dilutes a balanced shot, so it usually tastes cleaner and less bitter at the same strength.

How each shot tastes

A ristretto suits chocolatey, caramel-sweet coffees, since it concentrates their sweetness and body. Lungos tend to work better with coffees that can handle more extraction without turning harsh. Many baristas use ristretto shots in flat whites or cortados, where the milk benefits from a dense, sweet coffee base.

Caffeine: which is strongest?

Strength in taste and strength in caffeine are not the same thing. A ristretto tastes the most intense because it is the most concentrated, but it contains a little less total caffeine than a normal espresso from the same dose, since less water passes through. A lungo usually contains somewhat more caffeine than a normale, but not double, because caffeine dissolves early and a large share of it is already extracted in a normal shot.

For reference, a typical 30 ml single espresso contains around 65 mg of caffeine, and the INEI standard for certified espresso keeps it under 100 mg per cup. The biggest factor is the amount and type of coffee in the basket: a double dose has roughly twice the caffeine of a single, and Robusta contains considerably more caffeine than Arabica.

How to pull each shot at home

Start by dialing in a good normal espresso. If you need a refresher on dose, tamping and grind, see our guide on how to make espresso at home. Then adjust from there.

Ristretto

1. Keep the same dose, for example 18 g.
2. Stop the shot at about 18 to 27 g in the cup.
3. If it runs too fast and tastes sour, grind slightly finer so the shorter shot still takes 15 to 25 seconds.
4. Taste: it should be thick and sweet, not sharp.

Espresso (normale)

1. Use 18 g of coffee.
2. Aim for 36 to 45 g in the cup in about 25 to 30 seconds.
3. Adjust grind: finer if it runs fast and sour, coarser if it runs slow and bitter.

Lungo

1. Keep the 18 g dose.
2. Let the shot run to about 54 to 72 g.
3. Grind a little coarser than for espresso so the longer shot does not choke or over-extract; aim for roughly 30 to 45 seconds.
4. Taste: if it is harsh and drying, stop a bit earlier or coarsen the grind slightly more.

On capsule machines

Many capsule machines have separate ristretto, espresso and lungo buttons that change only the water volume. The principle is the same: a shorter cup is more concentrated, a longer cup is lighter and more bitter.

Which shot should you choose?

• You love sweet, intense coffee: try a ristretto, or use one as the base of a cortado or flat white.
• You want a classic, balanced shot: stay with a normal espresso.
• You want a bigger cup without adding water: choose a lungo, or compare it side by side with an Americano.

Coffees to try

Shot length changes how a coffee expresses itself, so it is fun to test with two contrasting blends. Our African Espresso combines coffees from Kenya, Tanzania and Ethiopia in a medium-dark roast with red fruit, chocolate and a lively finish; try it as a normale or a ristretto to concentrate its fruit and sweetness. For a deep, smoky cup, Italian Roast is our darkest roast, an Arabica and Robusta blend with a thick crema that shines as a ristretto and holds up in milk. Both are roasted 1–5 days before delivery and available in Espresso grind. You will find more options in our Blend collection.

Ristretto vs lungo FAQ

What is the difference between ristretto and lungo?

Both use the same dose of coffee. A ristretto stops early with about half the water of an espresso, giving a thick, sweet, intense shot; a lungo runs longer with about double the water or more, giving a lighter, more bitter cup.

Does a lungo have more caffeine than a ristretto?

Usually a little more, because more water extracts more caffeine. The difference is modest, since most caffeine dissolves early in the shot.

Is a lungo the same as an Americano?

No. In a lungo, extra water passes through the coffee during brewing. An Americano is an espresso diluted with hot water afterward.

Is a ristretto stronger than espresso?

It tastes stronger because it is more concentrated, but it contains slightly less caffeine than a normal espresso from the same dose.

What grind should I use for a lungo?

Slightly coarser than for espresso, so the longer shot flows at a reasonable speed and avoids harsh over-extraction.
