Espresso Shot: How Many Ml, How Many Calories, and 4 Types

How Many Ml Is an Espresso Shot?

One espresso shot is about 30 ml, which is 1 fluid ounce. That is a single shot. The US National Coffee Association calls 1 ounce "one shot" and says a shot brews in about 20 to 30 seconds. A double shot is about 60 ml. Here is every size in one place:

• Ristretto: 15 to 20 ml
• Single espresso: 25 to 30 ml
• Double espresso (doppio): 50 to 60 ml
• Lungo: 60 to 90 ml

If a cafe hands you about 60 ml and calls it an espresso, you were served a double. Many cafes pull a double as their house shot, so ask.

Single shot espresso ml and time: about 30 ml in 20 to 30 seconds. Double shot espresso ml and time: about 60 ml in the same 20 to 30 seconds. The double uses twice the coffee in a bigger basket, so it does not take longer.

Is there a standard espresso shot size? These are common cafe sizes, not a legal rule. Capsule machines use their own buttons. Nespresso lists 25 ml for a ristretto, 40 ml for an espresso and 110 ml for a lungo. Our InstaCuppa 3-in-1 machine has the same three buttons: 25 ml, 40 ml and 110 ml.

How Many Calories Are in an Espresso Shot?

An espresso shot is close to a zero calorie drink. The US Department of Agriculture lists cafe espresso at 9 kcal per 100 g. Espresso is 97.8% water, so 100 g is about 100 ml. A 30 ml single works out to about 3 calories and a 60 ml double to about 5 (USDA FoodData Central, FDC ID 171891).

Those calories come from 1.67 g of carbohydrate per 100 g, from the coffee that dissolves into the water. Nothing else in the cup carries energy. Everything you add does. Milk, sugar and syrup are where a 3 calorie shot becomes a 200 calorie drink.

What Is an Espresso Shot?

An espresso shot is a small, strong coffee made by pushing hot water through fine coffee grounds at high pressure. A standard single espresso shot uses 7-9 grams of coffee, takes about 20 to 30 seconds to pull, and gives you about 30 ml of rich, dark liquid topped with golden crema. That is the espresso shot meaning in one line: one small, measured pour.

Most people in India know espresso as "that tiny cup of strong coffee." But there are actually four distinct types of espresso shots. Each one uses the same coffee beans and the same machine. The difference? How much water passes through the grounds, and for how long.

I have pulled thousands of espresso shots on the InstaCuppa 3-in-1 Espresso Coffee Maker over the past year. Once you understand the four types, you can make any cafe drink at home. This guide breaks down each one in plain terms.

The 4 Types of Espresso Shots Explained

The four espresso shot types are ristretto, single, double (doppio), and lungo. They all start with the same espresso machine and the same coffee grounds. What changes is the brew ratio - how much water you push through the coffee, and how long the extraction runs.

1. Ristretto - The "Restricted" Shot

Ristretto means "restricted" in Italian. You use the same dose of coffee as the shot you would normally pull, whether that is 7 to 9 g in a single basket or 14 to 18 g in a double. But you stop the extraction early, at about 15 seconds instead of 25 to 30. That gives you only 15 to 20 ml of liquid.

The result? A sweeter, bolder, more concentrated shot. Because the water touches the grounds for less time, you get more of the sweet and fruity flavours. The bitter compounds do not have enough time to dissolve fully. Think of it like steeping tea for 1 minute versus 3 minutes - shorter time, milder bitterness.

Brew ratio: 1:1, so 18 g of coffee gives about 18 g of liquid in a double basket

2. Single Espresso - The Standard

This is the classic espresso shot you find in every cafe. It uses 7-9 grams of coffee in a single basket and produces about 30 ml of liquid in 20 to 30 seconds. Most modern cafes actually pull a "double" as their standard, but the single is where it all began.

The taste is balanced - you get sweetness, some fruit, a touch of bitterness, and that thick crema on top. It is the baseline that all other types are measured against.

Brew ratio: 1:2 (7 g coffee to 14 g liquid, or 18 g to 36 g for a modern double)

3. Double Espresso (Doppio) - Twice the Punch

Doppio is Italian for "double." You use 14-18 grams of coffee and pull about 60 ml of liquid. The extraction time stays the same - about 20 to 30 seconds. You just use a larger filter basket with more coffee.

The taste is the same as a single espresso, just more of it. Most specialty cafes in India now serve a doppio as the default "espresso" without telling you. If your cafe uses an 18-gram basket, your "single" is actually closer to a double by old Italian standards.

Brew ratio: 1:2 (14-18 g coffee to 28-36 g liquid)

4. Lungo - The "Long" Shot

Lungo means "long" in Italian. You use the same amount of coffee as a regular shot. But you let the water run for 45-60 seconds instead of 25-30. This gives you about 60-90 ml of liquid - roughly double a standard espresso.

More water means more extraction. The lungo pulls out deeper, roastier, and slightly more bitter flavours. It tastes lighter in body than a ristretto but has a rounder, more mellow flavour than drip coffee. Some people find it slightly bitter. Others love the smoothness.

Brew ratio: 1:3 to 1:4 (18 g coffee to 54-72 g liquid)

USDA data: Cafe espresso measures 212 mg of caffeine per 100 g, so a 30 ml single works out to about 63 mg. Bean type, roast level and the amount of coffee move this figure (USDA FoodData Central, FDC ID 171891).

Side-by-Side Comparison Table

This table compares all four shot types on dose, volume, time, caffeine, calories, taste and best use. Caffeine and calories are for a single dose of coffee, except the double. The single and double use the USDA values (212 mg caffeine and 9 kcal per 100 g). The ristretto and lungo use the ratios from a lab study at the Technical University of Munich, which pulled all three shots from the same coffee. Use it as a quick reference next time you order or pull a shot at home.

Caffeine Myth-Busting: Which Shot Has the Most?

A double espresso shot contains the most caffeine among espresso types - about 127 mg per serving at the USDA rate. But a common myth says that ristretto has "more caffeine because it is stronger." That is wrong. Stronger taste does not mean more caffeine.

Here is why: caffeine dissolves early in the extraction process. A ristretto stops early, so it gets less caffeine than a full espresso. A Technical University of Munich study pulled shots from the same 20 g of coffee. The ristretto held about 130 mg of caffeine, the normal espresso about 183 mg and the lungo about 204 mg. Scaled to a 63 mg single, a ristretto has about 45 mg. It tastes more intense because its caffeine is packed into less liquid. But the total amount is lower.

A lungo, on the other hand, runs longer and pulls out a little more caffeine - about 70 mg for a single-dose lungo. The extra water dissolves more caffeine from the grounds, but most of it already came out early.

The double shot wins on total caffeine simply because it uses twice the coffee. If you need a strong morning kick, a doppio is your best choice.

Key fact: Espresso carries far more caffeine per millilitre than drip coffee, 2.1 mg/ml against 0.4 mg/ml. But a full 240 ml cup of drip holds about 96 mg in total, which is more than a single espresso shot (espresso, FDC 171891; brewed coffee, FDC 171890). Strength per sip and total caffeine are two different things.

Which Shot Goes in Which Coffee Drink?

Different espresso drinks taste better with different shot types. A ristretto shines in milk-based drinks because its bold sweetness cuts through the milk. A lungo works best in drinks where you want more coffee volume without adding water separately.

Here is a simple guide:

• Latte: Double ristretto - the concentrated sweetness blends perfectly with 200+ ml of steamed milk
• Cappuccino: Single or double espresso - the balanced flavour holds up against equal parts milk and foam
• Flat white: Double ristretto - this is actually the traditional recipe, giving a stronger coffee flavour in a smaller drink
• Cortado: Single espresso or ristretto - the 1:1 ratio of coffee to milk means every drop of espresso matters
• Americano: Double espresso or lungo - you are adding hot water anyway, so start with a full extraction
• Long black: Lungo - pour the lungo over hot water for a clean, strong cup
• Macchiato: Single espresso - just a dot of milk foam, so the espresso flavour must be perfect on its own
• Straight shot: Ristretto if you like sweet and bold, lungo if you prefer smooth and mellow

On the InstaCuppa 3-in-1 Espresso Maker, you pick the shot size with a button: 25 ml, 40 ml or 110 ml. It has a 20-bar pump and a hot water mode, but no milk frother, so froth your milk separately for a latte or cappuccino. The machine is sold out on our store as of 13 October 2026.

How to Order Espresso Shots in India

Ordering espresso in India is easy once you know the right words. Specialty cafes such as Blue Tokai, Third Wave Coffee and Subko serve espresso drinks, so ask the barista if they pull a ristretto or a lungo. Many chain menus only list a "single" or a "double" shot.

Here is what to say at the counter:

• "One ristretto, please" - you will get a tiny, intense shot (15-20 ml)
• "A double shot espresso" or "doppio" - the most common order at specialty cafes
• "Can I get a lungo?" - some cafes may not offer this by name, so you can say "a long pull espresso"
• "Ristretto-based latte" - asks the barista to use a ristretto instead of a standard shot in your latte

Cafe prices change by city, so check the menu. At home, a double shot uses 14 to 18 g of coffee. If your beans cost Rs 1,000 per kg, that is Rs 14 to 18 of coffee per double shot. That is a big saving if you drink espresso every day.

Lab data: A University of Glasgow study tested 20 high-street espressos and found a 6-fold range in caffeine. The strongest single espresso held 322 mg. So ask whether your shot is a single or a double, and count it with care.
