Ristretto
A 'restricted' espresso shot pulled with the same coffee dose as a standard espresso but roughly half the water, stopped early for a smaller, more concentrated, sweeter shot with less bitterness extracted.

In short
A ristretto is an espresso made with the usual amount of ground coffee and roughly half the usual amount of liquid in the cup. The word means restricted. It is smaller, thicker and more intense than a standard espresso, and usually tastes sweeter and less bitter.
It is not simply a strong espresso. Stopping the shot early changes which parts of the coffee end up in the cup, and that is the reason to make one.
You are drinking the first half of the shot
CoffeeHQ explanation
An espresso does not come out of the machine evenly. The first liquid is dark, syrupy and very concentrated; as the shot runs, it becomes paler and thinner. The compounds that taste sweet and sharp dissolve early, and the more bitter and drying ones accumulate later.
A ristretto keeps the early part and leaves out the late part. That is why it is heavy-bodied and can taste sweet, and also why, pulled badly, it tastes sour: without the later part of the shot there is less bitterness to balance the acidity.
It is also the most concentrated way coffee is commonly served. The same dissolved coffee is carried in half the liquid, so the texture is close to a syrup and the flavour is intense enough that many people take it in two or three sips.
Ristretto in numbers
Typical range
| Variable | Typical range | What moving it does |
|---|---|---|
| Ground coffee | The normal espresso dose, about 16–20 g for a double | |
| Liquid in the cup | About 18–30 g for a double | A ratio of roughly 1:1 to 1:1.5, against about 1:2 for a standard espresso. |
| Time | About 15–30 seconds | Depends on which of the two methods below is used. |
| Caffeine | A little less than a full espresso from the same dose | Less water has passed through the coffee. |
There is no agreed boundary between a ristretto and a short espresso. Cafés draw the line in different places.
Two ways to make one, and they are not the same
CoffeeHQ explanation
- Stop early
- Keep the grind you use for espresso and stop the shot at half the yield. Quick and repeatable, but the short contact can leave the cup sharp, having taken little from the coffee.
- Grind finer
- Grind finer so that the smaller yield takes about as long as a normal shot. This extracts more from the coffee and gives a rounder, sweeter result, and it is the traditional approach. It needs a grinder with fine adjustment.
When a ristretto disappoints
CoffeeHQ explanation
- Sour and salty
Usually because: Usually too little taken from the coffee: the shot was stopped early without grinding finer to compensate. It is also a very strong drink, which can read as sharp.
Change first: Grind finer and keep the same yield.
- The machine chokes and barely drips
Usually because: The grind has gone too fine for the machine to push water through.
Change first: Grind slightly coarser.
- Lost in milk
Usually because: There is very little liquid, so a large milk drink swamps it.
Change first: Use it in small milk drinks, or use two.
Shorter, standard and longer
Tendency, not a guarantee
- Espresso — About twice the liquid from the same coffee. More balanced, less dense, with more bitterness to offset the acidity.
- Lungo — The opposite adjustment: the shot is run long, giving a thinner, more bitter cup.
- Flat white — Often made with a double ristretto in cafés that want a sweeter, heavier base under a small amount of milk.

Caffeine estimate
Approximately 108-198mg (the whole of an 18 g dose of arabica).
Inferred, not independently verified — CoffeeHQ's caffeine estimator's range for this recipe's dose. It is a model built from published measurements of other coffees, not a measurement of this drink. In the one study that weighed such shots, a short shot sat at the low end: the equivalent of 108 to 126 mg from 18 g at a 1:1 ratio.
Brewing method
Made using Espresso machine. Grind: Fine, sometimes slightly finer than standard espresso to slow the shorter pull.
Descriptive grind labels like this are illustrative starting points, not precise measurements — the same label can mean different particle sizes on different grinders. See the grind size guide for how to dial this in on your own equipment.
