Espresso Recipes
An espresso recipe is a set of measurable variables that defines how an espresso shot is prepared. These variables include the amount of ground coffee used, the volume of liquid extracted, the time it takes to pull the shot, and the temperature of the water. Together, they determine the strength, flavor balance, and character of the final drink.
Espresso recipes vary because no two coffees are identical. Different beans, roast levels, and grind settings all behave differently under pressure. A recipe dialed in for a dark-roasted Brazilian blend may produce a bitter, over-extracted result when applied to a light-roasted Ethiopian bean. Adjusting the recipe to suit the coffee is a normal and necessary part of espresso preparation.
The relationship between coffee dose, espresso yield, and extraction time – commonly called the brew ratio – is the central logic of any espresso recipe. Small changes to any of these variables produce measurable changes in the cup. Consistency matters because it allows the same result to be reproduced reliably. Without a consistent recipe, it becomes difficult to understand why a shot tastes the way it does or how to improve it.
What Is an Espresso Recipe?
Coffee Dose
The dose is the weight of dry ground coffee loaded into the portafilter before brewing. It is measured in grams. Most single-shot recipes use between 7 and 10 grams. Most double-shot recipes use between 16 and 20 grams. The dose influences the concentration and body of the espresso. A higher dose, all else equal, produces a stronger, more full-bodied result.
Espresso Yield
The yield is the weight of liquid espresso extracted into the cup. It is also measured in grams. Yield is distinct from volume because espresso is denser than water – 40 grams of espresso occupies slightly less than 40 millilitres. Measuring yield by weight rather than volume is more accurate and produces more consistent results.
Brew Ratio
The brew ratio expresses the relationship between dose and yield. It is written as dose:yield. A 1:2 ratio means that an 18-gram dose produces a 36-gram yield. This is the most common starting point for a standard double espresso. A ratio of 1:1.5 produces a more concentrated shot. A ratio of 1:3 or higher produces a longer, lighter shot.
Extraction Time
Extraction time refers to how long it takes the espresso machine to push water through the coffee puck and produce the target yield. For most standard espresso recipes, this falls between 25 and 35 seconds. Shots that finish significantly faster are usually under-extracted. Shots that take considerably longer are usually over-extracted. Time is one signal among several – it works alongside ratio and flavor to give an accurate picture of how the shot is performing.
Drink Size
Drink size is the total volume of the finished beverage. For a straight espresso shot, this is the yield itself. For milk-based drinks, it includes the milk added afterward. Understanding the intended drink size helps determine the appropriate espresso recipe to use as the base.
Essential Equipment
Espresso machine – An espresso machine forces hot water through ground coffee at pressure (typically 9 bar). The machine determines the water temperature, pressure consistency, and overall extraction environment. Without a machine capable of maintaining stable pressure and temperature, recipe results will vary regardless of how carefully other variables are managed.
Coffee grinder – Grind size has a direct impact on extraction speed and flavor. A burr grinder produces more uniform particle sizes than a blade grinder, which is important for consistent espresso. Espresso requires a fine grind, and the ability to make small, precise grind adjustments is essential when dialing in a recipe.
Scale – Measuring both the dose and the yield by weight removes guesswork from the recipe. A scale that reads to 0.1 grams allows accurate dose measurement. Placing the scale and cup under the portafilter during extraction allows the yield to be measured in real time.
Tamper – Tamping compresses the ground coffee in the portafilter basket into a level, even puck before brewing. An even tamp helps water distribute uniformly through the grounds. Most standard tampers are 58mm in diameter for commercial-size portafilter baskets.
Timer – Tracking extraction time allows comparison between shots. Even a phone timer is sufficient. Some espresso machines include a built-in shot timer.
Milk pitcher – Required for any milk-based espresso drink. A stainless steel pitcher with a spout allows steamed milk to be poured in a controlled way. Pitchers come in different sizes; smaller pitchers (300-350ml) work well for single drinks.
Understanding Espresso Ratios
The following table shows typical recipe ranges for common espresso styles. These are starting references, not fixed standards. Actual recipes may vary based on the coffee used, the machine, and personal preference.
| Style | Coffee Dose | Espresso Yield | Brew Ratio |
|---|---|---|---|
| Ristretto | 7-10g (single) / 14-18g (double) | 15-20g | 1:1.5 |
| Standard Espresso | 7-10g (single) / 16-20g (double) | 25-40g | 1:2 |
| Lungo | 7-10g (single) / 16-20g (double) | 40-60g | 1:3 to 1:4 |
| Double Espresso | 16-20g | 32-40g | 1:2 |
A lower ratio produces a smaller, more concentrated shot with more intense flavor and body. A higher ratio produces a larger yield that is lighter in concentration but may bring out more aromatic or acidic notes. Most recipe guides recommend starting at 1:2 and adjusting based on taste.

Recommended Starting Recipe
Variable | Starting Point |
Coffee dose | 18g |
Grind size | Fine (adjust based on extraction time) |
Water temperature | 92-94°C (198-201°F) |
Target yield | 36g |
Brew ratio | 1:2 |
Extraction time | 28-32 seconds |
Preparation Steps
- Warm the espresso machine and allow it to reach stable operating temperature.

- Place a cup and scale under the portafilter. Zero the scale.
- Start the timer and begin the shot.
- Stop extraction when the yield reaches 36 grams.
- Note the extraction time. If it falls between 28 and 32 seconds, the grind is in a suitable range. If it runs faster or slower, adjust the grind accordingly and repeat.
- Taste the shot. Adjust the ratio or grind on the next attempt based on flavor.
Double Espresso Recipe
The double espresso (also called a doppio) is the most common format served in cafés and the standard base for milk drinks. It uses a larger dose than a single shot and produces a proportionally larger yield at the same brew ratio.
Variable | Range |
Coffee dose | 16-20g |
Target yield | 32-40g |
Brew ratio | 1:2 |
Extraction time | 25-35 seconds |
Serving volume | Approximately 35-40ml |
A double espresso has more body and a stronger flavor presence than a single shot. It serves as the standard base for drinks such as flat whites, lattes, and Americanos. The flavor characteristics depend heavily on the coffee used, but a well-pulled double espresso typically shows sweetness, body, and a balance between acidity and bitterness.
Ristretto Recipe
A ristretto is a shorter, more restricted espresso shot. The same dose of coffee is used but less water is passed through it, producing a smaller, more concentrated yield. The word ristretto means “restricted” in Italian.
Because water contacts the grounds for less time and in smaller volume, the ristretto extracts differently than a standard shot. Early extraction compounds – which tend toward sweetness and acidity – make up a larger proportion of the final cup. Later extraction compounds, which introduce more bitterness, are reduced. The result is typically sweeter and more syrupy, though also more intense.
Variable | Range |
Coffee dose | 16-18g |
Target yield | 20-24g |
Brew ratio | 1:1.5 |
Extraction time | 15-20 seconds |
Flavor profile | Sweet, concentrated, low bitterness |
Ristretto is used as the espresso base in some milk drinks, particularly flat whites, where a more concentrated shot balances a higher proportion of milk.
Lungo Recipe
A lungo uses the same dose as a standard espresso but extracts a larger yield by allowing more water to pass through the grounds. The word lungo means “long” in Italian.
The longer extraction time and higher water volume draw out additional compounds from the grounds, including some that are more bitter and astringent. A lungo is not simply a diluted espresso – it is a fundamentally different extraction that produces a different flavor profile. It is lighter in body than a standard shot but more bitter, and the crema is often thinner.
Variable | Range |
Coffee dose | 16-18g |
Target yield | 48-60g |
Brew ratio | 1:3 to 1:4 |
Extraction time | 40-60 seconds |
Flavor profile | Lighter body, more bitter, lower concentration |
Lungo is sometimes used as a substitute for an Americano (espresso with added hot water), though the two are prepared differently and taste distinct from one another.
Espresso Drink Comparison
| Drink | Brew Ratio | Typical Volume | General Characteristics |
|---|---|---|---|
| Ristretto | 1:1.5 | 20-25ml | Concentrated flavor, increased sweetness, low bitterness, and a syrupy texture. |
| Espresso | 1:2 | 30-40ml | Balanced concentration with full body, moderate acidity, and moderate bitterness. |
| Double Espresso | 1:2 | 35-40ml | Uses the same ratio as a standard espresso but with a larger dose and volume. Commonly used as the base for milk-based drinks. |
| Lungo | 1:3 to 1:4 | 50-60ml | Lower concentration with increased extraction, often producing more bitterness and a thinner body. |
Espresso Recipes with Milk
Adding milk to espresso changes the character of the drink significantly. The ratio of espresso to milk and the texture of the milk define each drink as much as the espresso recipe itself. The following is a brief introduction to common milk-based espresso drinks. Each has its own detailed guide.
Cappuccino
A cappuccino uses a double espresso as the base and adds roughly equal parts steamed milk and milk foam. Total drink volume is typically 150-180ml. The foam provides texture and slightly insulates the drink. The espresso-to-milk ratio keeps the coffee flavor prominent.
Latte
A latte combines a double espresso with a larger volume of steamed milk – typically 150-200ml of milk for a total drink of 220-280ml. The milk is microfoamed (smooth and velvety rather than thick and stiff) and poured over the espresso. The higher milk ratio produces a creamier, milder drink.
Flat White
A flat white uses a double espresso (often a ristretto-style pull) with a smaller volume of steamed milk than a latte – typically 100-130ml total drink size. The milk texture is smooth microfoam with no thick foam layer. The higher espresso-to-milk ratio makes the coffee flavor more prominent than in a latte.
Macchiato
A macchiato is a shot of espresso “marked” with a small amount of steamed milk or milk foam. Traditional Italian macchiato (caffè macchiato) uses just a spoonful of foam. Some café styles use a small pour of steamed milk. The espresso flavor dominates entirely.
Cortado
A cortado pairs a double espresso with an approximately equal volume of warm (not heavily frothed) milk, typically in a 1:1 ratio. The milk is steamed but not textured into thick foam. The result softens the acidity of the espresso without significantly diluting it.
Mocha
A mocha combines espresso with chocolate (usually chocolate syrup or cocoa) and steamed milk. The chocolate is typically added to the cup before the espresso and milk. Total drink volume is similar to that of a latte. The sweetness of the chocolate balances the bitterness of the espresso.
How Variables Affect Espresso Recipes
Coffee Dose
Increasing the dose, while keeping the yield and extraction time the same, generally increases the body and richness of the espresso. Decreasing the dose produces a thinner, less intense shot. Dose changes usually require a corresponding grind adjustment to maintain the target extraction time.
Grind Size
Grind size is the primary tool for adjusting extraction speed. A finer grind slows the flow of water through the puck and increases extraction. A coarser grind speeds the flow and reduces extraction. If the shot runs too fast and tastes sour or thin, grind finer. If it runs too slowly and tastes bitter or harsh, grind coarser. Grind adjustments should be small – one to two settings at a time.
Water Temperature
Higher water temperatures extract more aggressively. Lower temperatures extract more slowly and can leave certain flavor compounds underdeveloped. For most espresso, 92-94°C is a practical starting range. Light roasts sometimes benefit from slightly higher temperatures (93-96°C) because they are denser and less soluble. Dark roasts may perform better at slightly lower temperatures (90-92°C) to reduce bitterness.
Brew Ratio
The brew ratio has the most direct impact on the perceived strength and flavor balance of the espresso. A tighter ratio (1:1.5) produces a more concentrated, sweeter, syrupy shot. A wider ratio (1:2.5 or beyond) produces a lighter, more aromatic shot with less body. Most recipes start at 1:2 and adjust based on tasting.
Extraction Time
Extraction time reflects how quickly water moves through the coffee puck at a given grind setting. It is a consequence of the grind and dose rather than an independent variable – the grinder adjustment controls the time. A shot that extracts in under 20 seconds at the target yield is likely under-extracted (too coarse). A shot that takes over 40 seconds is likely over-extracted (too fine).
Roast Level
Roast level affects how a bean behaves under extraction. Lighter roasts are denser, less soluble, and often require a finer grind and slightly higher temperature to extract properly. Darker roasts are more soluble and can become bitter quickly if over-extracted. This means that the same recipe settings will not produce equivalent results across different roast levels, and some adjustment is expected when switching coffees.
Common Espresso Recipe Mistakes
| Issue | Possible Cause | Adjustment |
|---|---|---|
| Sour espresso | Under-extraction; grind too coarse or shot time too short. | Grind finer or increase extraction time by adjusting the yield slightly. |
| Bitter espresso | Over-extraction; grind too fine or shot time too long. | Grind coarser or reduce extraction time. |
| Weak espresso | Dose too low, brew ratio too wide, or grind too coarse. | Increase dose, tighten the ratio, or grind finer. |
| Fast extraction | Grind too coarse; coffee puck provides insufficient resistance. | Grind finer in small increments to slow the flow rate. |
| Slow extraction | Grind too fine; coffee puck provides excessive resistance. | Grind coarser in small increments to increase flow rate. |
| Uneven extraction | Uneven distribution or tamping; channeling occurs within the coffee puck. | Distribute grounds evenly before tamping and ensure the tamp is level. |
Channeling occurs when water finds a path of least resistance through the puck rather than flowing evenly through all the grounds. It can cause both under- and over-extracted compounds to appear in the same shot. An even distribution of grounds and a level tamp help prevent it.
Espresso Recipes for Different Roast Levels
Light Roasts
Light roasts retain more of the bean’s original character – often fruity, floral, or tea-like. They are denser than dark roasts and require more energy to extract. When working with light roasts, starting with a slightly finer grind than expected and a water temperature in the 93-96°C range often produces better results. A brew ratio of 1:2 to 1:2.5 can help bring out sweetness and fruit notes without excessive acidity. Light roasts often taste more acidic at first – this can sometimes be addressed by adjusting the ratio rather than only the grind.
Medium Roasts
Medium roasts tend to balance origin flavors with some degree of roast character, making them more forgiving across a range of recipes. A standard 1:2 ratio at 92-94°C is a reliable starting point. Medium roasts often show good body, moderate acidity, and sweetness that holds well with milk. They are a practical starting point for those new to dialing in espresso recipes because they respond predictably to grind adjustments.
Dark Roasts
Dark roasts are more soluble than lighter roasts, meaning they extract quickly and can become bitter or harsh if the recipe is not adjusted accordingly. A slightly coarser grind than expected, a lower brew temperature (90-92°C), and a tighter ratio (1:1.5 to 1:2) can help control bitterness and highlight the roasty, chocolatey, or nutty notes that dark roasts commonly produce. Short extraction times work well for dark roasts – longer shots tend to accentuate harsh flavors rather than improve sweetness.
Espresso Recipes and Milk Drinks
Espresso for Cappuccinos
Cappuccinos use a double espresso as the base with a relatively small total volume, so the espresso needs to be well-balanced and present in the final drink. A standard 1:2 ratio works well. The foam layer in a cappuccino provides some insulation and texture, so the espresso temperature at the point of serving matters – a shot that cools too much before milk is added will produce a lukewarm drink.
Espresso for Lattes
A latte uses a larger milk-to-espresso ratio than most other drinks, which means the espresso character is softened considerably. Some baristas pull a slightly shorter shot (closer to 1:1.8) for lattes to ensure the espresso flavor is not entirely lost in the milk. The roast level also matters – a darker, bolder espresso holds up better in a high-milk drink than a very light, delicate one.
Espresso for Flat Whites
Flat whites use a smaller total volume and a higher espresso-to-milk ratio than lattes, so the espresso base has more influence on the final drink. A ristretto-style pull (1:1.5) is sometimes preferred for flat whites, producing a sweeter, less bitter espresso that pairs well with the small amount of smooth microfoam used in the drink.
Espresso for Iced Drinks
When espresso is used as the base for iced drinks – such as iced lattes or shaken espresso – dilution from ice needs to be considered. A slightly tighter brew ratio or a higher dose helps preserve flavor concentration after ice is added. Some recipes call for pulling the shot directly over a small amount of ice to chill it immediately and reduce heat-related bitterness.
Customizing Espresso Recipes
Stronger Espresso
To make a stronger espresso, either increase the dose while keeping the yield the same, or reduce the yield while keeping the dose the same (producing a tighter ratio). A tighter ratio (1:1.5 to 1:1.8) creates a more concentrated cup. When increasing the dose, note that the extraction time may change and a grind adjustment may be needed.
Lighter Espresso
A lighter espresso can be achieved by widening the brew ratio (pulling more yield from the same dose) or by reducing the dose. A ratio of 1:2.5 or 1:3 produces a longer, lighter shot with less body and concentration. This approach works well with light roasts where bright, delicate flavor notes are the goal.
Higher Yield Recipes
Higher yield recipes (longer ratios) are appropriate when the coffee is very dense or when a lighter cup is preferred. Yields beyond 1:3 begin to resemble a lungo and carry more extracted bitter compounds. These recipes can work well for certain light roasts but tend to over-extract darker roasts.
Lower Yield Recipes
Lower-yield recipes (tighter ratios) concentrate the espresso and reduce the contribution of later-extracted bitter compounds. They are useful for milk drinks where the espresso needs to hold its presence against a large milk volume, or when a syrupy, sweet shot is the goal. Grind adjustments are usually needed when significantly changing the target yield.
The most reliable method for customizing a recipe is to change one variable at a time and record the result. Making multiple adjustments simultaneously makes it difficult to identify which change produced which outcome.

Frequently Asked Questions
The most commonly used starting point is 1:2 – one gram of coffee for every two grams of espresso yield. For an 18-gram dose, this means pulling approximately 36 grams of espresso. This ratio is a starting point, not a fixed rule, and most recipes are adjusted from there based on the coffee and taste.
Both use the same dose of coffee, but a ristretto uses less water, producing a smaller yield at approximately a 1:1.5 ratio instead of a 1:2 ratio. The ristretto extracts primarily the early-stage compounds, which tend toward sweetness and acidity, while reducing the contribution of later-stage bitter compounds. The result is more concentrated and often sweeter than a standard espresso.
A lungo is a longer espresso shot that uses the same dose but extracts a larger yield – typically at a 1:3 to 1:4 ratio. More water passes through the grounds over a longer extraction time, drawing out additional compounds, including more bitter ones. A lungo is lighter in concentration than a standard shot but more bitter. It is not the same as an Americano, which is espresso with hot water added after extraction.
Sourness in espresso typically indicates under-extraction. The most common causes are a grind that is too coarse, allowing water to pass through too quickly; a dose that is too low; or a yield that is too small relative to the dose. Grinding finer, increasing the dose, or pulling a slightly higher yield will usually address the sourness.
Yes. Espresso recipes are starting points, not fixed formulas. The standard 1:2 ratio at 92-94°C with a 28-32 second extraction is a practical baseline, but the right recipe depends on the specific coffee, the machine, and the intended drink. Adjusting the grind, dose, ratio, or temperature in small increments and tasting the result is the standard approach to dialing in a recipe.
A Final Note
Espresso recipes involve a small number of variables, but those variables interact closely. Changing one typically requires adjusting another to maintain balance – which is why understanding how dose, yield, grind, and time work together matters more than memorizing a single set of numbers.
