Espresso Brew Ratio Explained
Ristretto, normale, lungo – what the ratio means and which one fits which taste.
Brew ratio describes how much espresso you pull from a given amount of grounds. It is one of the simplest levers to steer strength and taste on purpose.
What does 1:2 mean?
1:2 means: from 1 part grounds you pull 2 parts espresso – roughly 18 g of grounds into 36 g in the cup. It is the most common starting point for modern espresso.
Ristretto, normale, lungo
Ristretto (about 1:1 to 1:1.5) is concentrated, syrupy and sweet. Normale (about 1:2) is balanced. Lungo (about 1:3 and more) is lighter and more extracted, but can turn bitter faster.
How to calculate the ratio
Divide the output weight by the dose. 18 g into 36 g = a 1:2 ratio. A scale makes this exact and reproducible.
Which ratio for which taste?
Change the ratio in small steps and taste – the sweet spot is a matter of preference.
- More sweetness and body: toward ristretto (1:1.5).
- Balanced for milk drinks and straight: 1:2.
- Lighter, more tea-like: toward lungo (1:3).
Common ratio questions
Is a lower ratio stronger?
More concentrated, yes. Ristrettos feel more intense because less water runs through the same amount of coffee.
Is ratio linked to grind?
Yes. If you change the ratio, the right grind setting usually changes too – best to adjust one at a time.
