Expert Overview
Your grinder churns out 18 grams of coffee. Your machine extracts it in 28 seconds. You get 36 grams of liquid in the
cup. But what does all of this actually mean? And why do espresso bars offer ristretto, normale, and lungo — and how
are they different?
This guide demystifies espresso ratios completely: what they mean, how to use them, and how to choose the right ratio
for your beans and taste preference.
What Is an Espresso Ratio?
An espresso ratio is simply the relationship between the weight of dry coffee grounds you put into the portafilter
(the dose, measured in grams) and the weight of liquid espresso that comes out into your cup (the yield, measured in
grams).
It’s written as dose : yield — so 18g in, 36g out = a 1:2 ratio.
Why weight, not volume? Because coffee density changes. A gram of finely ground espresso and a gram of coarsely
ground pour-over produce different volumes. Weight is the only reliable, repeatable measurement. Always weigh your
dose and yield — a precision scale is not optional for anyone serious about espresso.

Check PriceThe Three Classic Espresso Ratios
Ristretto — 1:1 to 1:1.5
A ristretto (Italian: “restricted”) is a short, concentrated shot pulled by stopping extraction early. Using 18g in,
you’d stop at 18–27g out. Because extraction stops before the bitter, higher-solubility compounds dissolve, a
ristretto tastes intensely sweet, syrupy, and chocolatey with almost no bitterness. The texture is remarkably thick.
Ristrettos are the secret weapon in specialty coffee milk drinks — many top baristas use a 1:1.5 ristretto as the
espresso base in their flat whites because the concentrated sweetness cuts through milk more effectively than a
normale.
Normale — 1:2 to 1:2.5
The normale is the classic espresso. With 18g in, you target 36–45g out in 25–35 seconds. This is the most balanced
ratio — sweet, acidic, and bitter compounds are all present in proportion. You get full crema development, a
pronounced aroma, and enough volume to drink as a standalone shot or use as a foundation for any milk drink.
Most recipes and coffee bag brewing notes reference the 1:2 normale as their baseline. Start here every time you open
a new bag before experimenting further.
Lungo — 1:3 to 1:4
A lungo (“long” in Italian) extracts more liquid from the same dose. 18g in, 54–72g out. Because extraction continues
further, more bitter, astringent compounds dissolve into the drink. Lungos are larger in volume and lower in overall
sweetness — more similar in character to a concentrated drip coffee than a true espresso.
Lungos are often misunderstood. They are not just “more espresso” — they represent a fundamentally different
extraction window and are best suited to specific bean profiles (often light-roasted, high-acid naturals). Automatic
capsule machines like Nespresso use programmed lungo ratios to accommodate users who prefer a longer drink without
an Americano.
How Ratio Affects Flavor
| Ratio | Character | Best for |
|---|---|---|
| 1:1 – 1:1.5 (Ristretto) | Thick, sweet, syrupy, no bitterness | Milk drinks, dark roasts |
| 1:2 – 1:2.5 (Normale) | Balanced, full crema, complete flavor | Straight shots, most milk drinks |
| 1:3 – 1:4 (Lungo) | Larger volume, more bitter, herbal | Light roasts, longer drinks |
Ratio vs. Time: Two Different Things
A common confusion: grind size controls time, not ratio. Ratio is controlled by when you stop your pump. You
can have a 1:2 ratio that takes 20 seconds (under-extracted, too coarse) or 45 seconds (over-extracted, too fine).
The ratio and the time must both be in range simultaneously for a well-extracted shot.
This is why a scale and a timer working together are both essential. A scale alone tells you your yield. A timer
alone tells you your flow rate. Together, they let you diagnose whether a problem is a ratio issue or a grind issue.

Check PriceChoosing Your Starting Ratio
When brewing a new coffee for the first time: always start at 1:2. It is the most forgiving, best-documented, and
most widely tested ratio in espresso. If the shot tastes balanced but thin, try 1:1.75. If it tastes harsh and
bitter, try 1:2.2. Small ratio adjustments make big flavor differences — move in 0.1–0.2 increments and taste after
every change.
