Italian Ristretto Double Shot
Caffè Ristretto
A double ristretto: 18 g in, about 22 g out, pulled short for sweetness and weight.
A double ristretto is an espresso built from a full double dose of coffee and cut short. Here that means 18 g of finely ground coffee and about 22 g of liquid in the cup after 15 to 20 seconds.

- Filtered water for the machine
Required gear
- Espresso machine capable of 9 bar
- Burr grinder with fine adjustment
- Portafilter with the right basket

- Timer
- Warm cup
Step-by-step protocol
- 0:00Warm the cup and portafilter. Dose 18 g of finely ground coffee into the basket, level the bed, and tamp flat and even.
- 0:20Lock the portafilter in and start the shot and the scale together, with water at about 93°C and 9 bar.
- 0:30The first drops should appear after a few seconds and run as a thick, honey-colored stream.
- 0:40Stop the shot at about 22 g in the cup, after roughly 15 to 20 seconds. Serve at once, because a ristretto is small and loses heat fast.
Troubleshooting
What it may be good for
The caffeine count
We list about 110 mg for this double ristretto as an editorial estimate. A ristretto holds less caffeine than a normal shot from the same dose, because less water passes through the coffee: in one 2023 laboratory study, a 1:1 shot from 20 g of coffee held about 130 mg against about 183 mg for a 1:2 shot. Treat our figure as an estimate, and remember that your cup depends mainly on how much coffee goes in the basket.
A shot for sipping
Because it is so concentrated, a ristretto is a drink to sip slowly. Taste it hot, then again as it cools, when the sweetness comes forward.
What to watch out for
- Caffeine affects everyone differently. If you are pregnant or nursing, sensitive to caffeine, or have been told to limit it, check with your doctor about how much is right for you.
- Bright, high-acid coffees can feel sharp on an empty stomach for some people, so a little food with it helps.
A double ristretto is an espresso built from a full double dose of coffee and cut short. Here that means 18 g of finely ground coffee and about 22 g of liquid in the cup after 15 to 20 seconds. The result is dense, syrupy and sweet, with little bitterness.
Origin & Story
Pulling a double ristretto
Ristretto means restricted, and this page is about the double version: the same dose of coffee you would use for a normal double, with far less water through it. If you want the definition and the reasoning behind it, our guide to what a ristretto is and how it differs from a normal shot covers that. Here is how to pull one.
Weigh 18 g of coffee into a double basket. That sits inside the 18 to 22 g range usually given for a double, and it is the dose most ristretto guides use. Set the grind finer than your normal espresso setting, anywhere from your usual grind to one or two settings finer. A finer grind slows the water, so the shot can stop at a short yield without running through too fast. Heat the water to 93°C and run the machine at 9 bar; guides give 92 to 96°C as the usual window.
Put a scale under the cup and stop the shot at about 22 g. Judge by weight, not by volume, because crema inflates volume and makes a short shot look larger than it is. At 18 g in and 22 g out, the ratio is roughly 1 to 1.2.
Why the numbers disagree
Guides give different recipes, and that is useful to know before you chase a number. For 18 g of coffee, one gives 18 to 22 g out in 14 to 20 seconds and another 18 to 25 g in about 15 to 20 seconds. Two more say 1 to 1, coffee to water, and a fifth recommends 27 g in 25 to 30 seconds and calls 1 to 1 unbalanced and harsh. One lists 15 to 20 ml as the volume of a single ristretto.
These are not contradictions so much as points on a line between a normal shot, which the same sources put at 1 to 2 or 36 to 40 g, and a very short one. Pick a ratio and hold it. We use 22 g because it is a clear step away from a normal shot, and we treat the time as a result of the grind rather than a target: with a finer grind and a shot stopped by weight, the clock settles where it settles. If your 22 g runs in 15 to 20 seconds, that is a fast flow and a reasonable one. If it takes much longer than 30 seconds to reach 22 g, the grind is probably too fine.
When it goes wrong
A sour, thin ristretto is under-extracted. Grind finer, or let a little more liquid through. A harsh or bitter one is over-extracted, or the water is running through channels; grind a step coarser and level the grounds, tapping the portafilter or using a distribution tool. Too fine a grind can choke the machine, with almost no flow.
The coffee matters too. One guide recommends darker roasts, because a lighter roast can give a weak shot in 15 seconds, while another recommends fresh light to medium roasts and warns that very dark, stale or oily beans give an ashy, harsh cup. The two views are less opposed than they sound: a fresh medium roast with some chocolate in it is the safe middle. Bright, sharp coffees are the riskiest choice because a ristretto stresses the acids that come out first.
A short history of the machine
Ristretto only exists because the machine does. Angelo Moriondo of Turin patented a steam-driven coffee machine in 1884. Luigi Bezzera applied for a patent for a single-cup unit in Milan in 1901. Desiderio Pavoni bought the patent in 1903 and the La Pavoni company dates from 1905. Achille Gaggia filed a patent in 1938 for a steamless machine that used pressurized hot water and produced crema, and Gaggia's lever machine followed in the late 1940s. Dates for the early machines vary by a year or two between sources, but the order is the same everywhere.
What it adds up to
A double ristretto is a small, dense drink, best sipped. The tasting notes here are sweet, syrupy, low in bitterness and rich in body, and the best test of whether yours is right is whether you want a second sip. If it is sharp, grind finer. If it is flat and harsh, grind coarser.

How much caffeine is in Italian Ristretto Double Shot?
One serving, 1.5 oz double shot, contains approximately 110 mg of caffeine.
What temperature should I use for Italian Ristretto Double Shot?
Target 93°C (199°F) at the group head. Too cool and the shot runs sour and thin; too hot and it turns bitter and ashy.
How long should Italian Ristretto Double Shot be extracted?
Timing: 15-20 seconds. Method: 9-Bar Espresso Machine. Ratio: 18g in, 22g out (1:1.2). Grind or leaf format: Fine (finer than for a normal shot).
Why does my Italian Ristretto Double Shot taste bitter?
Bitter espresso is usually over-extraction: the shot ran too long, the grind is too fine, the water is too hot, or the roast is very dark. Grind a little coarser, stop the shot at about a 1:2 ratio (18 g of coffee to 36 g in the cup, for example), and change one thing at a time.
How much coffee and how much liquid for a double ristretto?
We use 18 g of ground coffee in a double basket and stop the shot at about 22 g in the cup, a ratio of roughly 1 to 1.2, in 15 to 20 seconds. Guides range from 18 g out up to 27 g, so choose one ratio and adjust the grind to hit it.
Should I grind finer for a ristretto?
Yes, usually a notch or two finer than for a normal shot. The finer grind slows the water, which is why a smaller amount of liquid takes a reasonable time. Stopping a normal shot early without changing the grind tends to give a sour, thin cup.
How long should a double ristretto take?
Our recipe runs about 15 to 20 seconds, which matches several guides, while others run 25 to 30 seconds with a longer yield. Stop by weight and use the time as a check on the grind, not as the target.
Why does my ristretto taste sour or bitter?
Sour and thin means under-extraction: grind finer or let more liquid through. Bitter and harsh means over-extraction or channeling: grind a step coarser and level the grounds before tamping. Very dark, stale or oily coffee can also taste ashy.
Does a ristretto have more caffeine than a normal shot?
Less, because less water passes through the same dose of coffee. In one 2023 laboratory study, a 1:1 shot from 20 g of coffee held about 130 mg of caffeine against about 183 mg for a 1:2 shot. The dose you put in the basket matters too.
Who should avoid Italian Ristretto Double Shot?
Caffeine affects everyone differently. If you are pregnant or nursing, sensitive to caffeine, or have been told to limit it, check with your doctor about how much is right for you. Bright, high-acid coffees can feel sharp on an empty stomach for some people, so a little food with it helps. This information is educational and is not medical advice. If you are pregnant or breastfeeding, managing a cardiac or gastrointestinal condition, or taking prescription medication, discuss caffeine and botanical intake with a qualified healthcare professional before making changes.
