Making espresso at home becomes much easier once you measure the coffee going in and the drink coming out. Start with a dose that suits your basket, aim for roughly twice that weight in the cup and use grind size to control the flow. That gives you a repeatable starting point; taste then tells you whether the final recipe needs to run shorter, longer, finer, coarser or at a different temperature.
Use about one gram of dry coffee for every two grams of espresso in the cup, then adjust to taste.
Keep the dose and output fixed and move slightly finer, provided the flow looks reasonably even.
Move slightly coarser and check that the basket is not overfilled or the machine badly restricted.
Taste the coffee before diagnosing it. Crema varies with the bean, roast, age and basket and is not a quality score by itself.
What you need before you start
The exact setup depends on the basket supplied with your machine. A single-wall basket needs freshly ground coffee and an espresso-capable grinder. A pressurised or dual-wall basket is more tolerant of pre-ground coffee and a less precise grinder, making it a useful starting point when you do not yet own a full espresso setup.
An espresso machine and matching basket
Identify whether the basket is single-wall or pressurised and use the dose range recommended for its size.
A small digital scale
Weighing the dry dose and liquid output makes adjustments repeatable and is more useful than judging the cup by volume.
An espresso-capable burr grinder
The grinder needs small enough adjustment steps to control the flow through the coffee puck.
A correctly sized tamper
The diameter must match the basket. Domestic machines commonly use several sizes, so do not assume that every portafilter needs a 58mm tamper.
Beans you enjoy
An espresso-labelled blend can be an approachable starting point, but any coffee can be used when the recipe suits the roast and your taste.
Fresh water suited to the machine
Use water that tastes clean and follows the machine maker’s guidance on hardness, filters and unsuitable types.
A scale is more than an enthusiast accessory
Without one, a change in cup volume may come from crema rather than extra liquid coffee. Measuring by weight lets you stop each shot at the same output and see what the grind adjustment actually changed.
Choose the right filter basket
Easier with pre-ground coffee
The basket creates much of the resistance through a restricted outlet, so the grinder and puck preparation are less critical.
- Suitable for supermarket or roaster-ground coffee
- More forgiving while learning the machine
- Less responsive to small grind adjustments
- Can produce crema-like foam even when the coffee is not freshly ground
More control over extraction
The coffee puck provides the resistance, so grind size, dose and even distribution have a much greater effect.
- Needs a grinder capable of espresso adjustment
- Responds clearly when you move finer or coarser
- Gives more control over the finished recipe
- Exposes channeling and inconsistent preparation more readily
Some machines include both basket types. Start with the pressurised basket when using pre-ground coffee, then move to single-wall once you have a suitable grinder and want more direct control. Sage’s current Bambino, for example, includes both single- and dual-wall baskets.
A sensible starting espresso recipe
Use the dose intended for the basket. If it is an 18g basket, begin with about 18g of ground coffee; a smaller domestic basket may be designed for considerably less. Do not force 18–20g into every machine simply because it is common in cafés.
Example: 18g in, about 36g out
A shot completed in roughly 25–30 seconds is a useful first reference, but not a pass-or-fail rule. Acceptable recipes can run shorter or longer and can use a tighter or more open ratio depending on the coffee and machine.
Choose one consistent way to time the shot—either from pressing the brew button or from the first visible drops—and use the same method for every comparison. Stop by output weight rather than letting time decide when the shot ends.
How to make espresso at home step by step
Prepare the machine
Fill the tank with suitable fresh water and follow the machine’s warm-up guidance. A fast-heating machine may be ready quickly, but warming the portafilter and cup can still improve temperature consistency.
A short water flush can warm compatible equipment, but use the exact machine instructions.Weigh the dose
Place the empty portafilter on the scale, tare it and add the quantity of coffee suited to the basket. Keep this dose unchanged while making initial grind adjustments.
If the basket is visibly overfilled or the puck touches the group outlet, reduce the dose.Grind for controlled flow
Use the grinder maker’s espresso range as a starting point. Visual descriptions such as table salt are too imprecise for dialling in, so judge the setting by the measured shot.
See the espresso grind-size guide for a fuller dial-in process.Distribute the grounds
Settle and spread the coffee so the basket is filled evenly before tamping. Avoid leaving a mound on one side or knocking the portafilter hard after the puck is prepared.
A simple needle distribution tool can help with clumps, but careful technique matters more than buying several levelling gadgets.Tamp level and firmly
Press straight down until the puck is compressed, keeping the tamper level. There is no need to chase a precise kilogram figure or apply excessive force once the coffee has stopped compressing.
A level, repeatable tamp is more useful than polishing the surface with a heavy twist.Lock in and start promptly
Clear loose grounds from the basket rim, insert the portafilter and begin brewing without leaving the prepared coffee in a hot group head for an extended period.
Place the cup and scale in position before locking in so the process stays consistent.Stop at the target weight
End the shot when the scale reaches your chosen output. Note the time and observe whether the flow looked even, patchy, unusually fast or badly restricted.
A dark-to-lighter colour change is normal; do not use colour alone to decide when to stop.Taste, record and clean
Stir the espresso so the layers are combined, taste it once it is comfortable to drink and record the dose, output, time and grinder setting. Then discard the puck and rinse the coffee-contact parts.
Use the espresso-machine cleaning guide for machine-specific care.How to evaluate the shot
Crema can be attractive and informative, but its quantity and colour are affected by roast level, coffee age, species, processing and whether the basket is pressurised. A thick layer does not prove that the espresso is balanced, and a thinner layer does not automatically mean it has failed.
Stir the shot before tasting. Look for balance between sweetness, acidity and bitterness, together with a texture and strength you enjoy. Some coffees are naturally bright or bitter-toned, so the aim is not to remove every trace of acidity or bitterness.
Signs the recipe is close
- The flow is repeatable from shot to shot
- No obvious spurting or isolated fast channels
- The flavour feels connected rather than hollow or aggressively dry
- The strength suits whether you drink it straight or with milk
Reasons to adjust
- The target output arrives far too quickly or slowly
- The flavour is sharply sour, hollow, woody or strongly drying
- The machine chokes or produces only intermittent drips
- The result changes significantly despite repeating the same recipe
How to dial in the espresso
Hold the basket, dose and output steady while using grind size to bring the shot into a sensible flow range. Once the shot is repeatable, adjust output or temperature to refine the taste. Change one variable at a time so the result remains understandable.
| What happens | First adjustment | What else to check |
|---|---|---|
| Target weight arrives much too quickly | Move slightly finer. | Confirm the dose is not low and the puck is not visibly channeling. |
| Machine drips slowly or barely flows | Move coarser. | Check that the basket is not overfilled and its holes are clear. |
| Flow is sensible but the shot is sharply sour | Try a little more output or a slightly finer grind. | Consider brewing temperature and whether extraction looks even. |
| Flow is sensible but the shot is dry or harsh | Try a shorter output or slightly coarser grind. | A very dark roast may also suit a lower temperature. |
| Shot sprays or runs strongly from one area | Improve distribution and tamping first. | Check dose, basket cleanliness and whether the grind is excessively fine. |
| Timing changes from shot to shot | Repeat the preparation before moving the grinder repeatedly. | Weigh the dose, account for grinder retention and keep the hopper supplied consistently. |
Time is a diagnostic measurement, not the flavour target
A 28-second shot can still taste poor if the output, temperature or puck preparation is wrong. Equally, a shorter or longer shot can taste excellent. Use time to compare changes, then make the final decision by taste.
Common espresso problems
The shot gushes into the cup
Move finer if the puck is prepared evenly. With pre-ground coffee in a pressurised basket, check the dose and whether the coffee is suitable for espresso.
The machine chokes
Move coarser, reduce an excessive dose and make sure the basket is not blocked. Do not keep running the pump against a fully restricted puck.
The espresso sprays or spurts
Review distribution, tamp level and basket fill. Going too fine can also make the puck unstable and encourage water to find isolated paths.
Sour and thin
After confirming even flow, try a finer grind or slightly longer output. Also check that the machine and portafilter are adequately warmed.
Bitter and drying
Try a shorter output or coarser grind. Clean the basket and group outlet as stale coffee residue can also make flavour harsher.
Very little crema
Taste before changing the recipe. Coffee age and roast have a large effect, and a single-wall basket normally behaves differently from a pressurised one.
Choosing beans and water
Coffee
Start with a coffee whose flavour description appeals to you. Medium and medium-dark blends can be easier for beginners because their recipes often tolerate a wider range, but there is no requirement to use an “espresso roast”. Lighter coffees may benefit from a longer ratio, finer grind or higher brewing temperature.
A roast date is useful, but there is no universal expiry point after four, six or eight weeks. Packaging, roast level and storage all affect how a coffee develops. Keep the bag sealed away from heat and light, use the coffee while it tastes lively and expect to adjust the grinder as it ages.
Water
Water affects both flavour and scale formation. Use clean-tasting water that meets the machine maker’s guidance, and set the machine’s hardness level to match the water entering the tank. Avoid assuming that every filter jug produces suitable espresso water or that distilled water is automatically the right solution.
For hard-water areas, use the compatible in-tank filter or treatment approach recommended for the machine and follow the maintenance prompts. See the descaling guide for more detail.
Accessories that genuinely help
A responsive scale
Most useful first purchase. Choose one that fits beneath the cup and reads small changes quickly. A 0.1g display is helpful for dosing.
A well-fitting tamper
Useful when the supplied tamper is loose or awkward. Match the basket’s actual internal diameter rather than buying 58mm by default.
A simple needle tool
Helpful for breaking up clumps. It can improve distribution, particularly with grinders that leave dense clumps in the basket.
A dosing funnel
Mainly a mess-reduction tool. It keeps grounds inside the basket while grinding or distributing and is especially useful with smaller portafilters.
A bottomless portafilter
Optional diagnostic tool. It can expose channeling, but it is not required for good espresso and must match the exact machine.
A shot log
Free and surprisingly useful. Record coffee, dose, output, time, grinder setting and a short tasting note while learning.
Things you do not need immediately
Several overlapping distribution tools
Start with even dosing, a simple needle tool if needed and a level tamp. Extra levellers do not automatically solve channeling.
A precise tamp-pressure target
Once the coffee is firmly compressed, levelness and repeatability matter more than trying to reproduce an exact force number.
Crema-focused shot glasses
A normal cup on a scale gives more useful information than measuring foam volume or trying to match a particular crema colour.
A new basket before learning the supplied one
Premium baskets can be useful later, but they may demand a better grinder and more precise preparation than the original basket.
The key takeaway
Choose a dose that suits the basket, set a measured output and use grind size to control the flow. A roughly 1:2 ratio and a shot around 25–30 seconds make a useful starting point, but the final recipe should be decided by evenness, repeatability and taste.
Do not judge the shot by crema alone, force every machine to accept 18–20g or buy a collection of accessories before you can repeat the basic recipe. Consistent measurement and one adjustment at a time will take you further.
Frequently asked questions
What is a good starting espresso ratio?
About 1:2 is a practical place to begin: 18g of coffee would produce roughly 36g of espresso. Treat it as a reference and adjust the output to suit the coffee and your preferred strength.
Does every double espresso use 18–20g?
No. The correct dose depends on the filter basket. Many modern café baskets are designed around that range, while smaller domestic baskets may require less and some larger baskets require more.
Do I need a grinder to make espresso?
A single-wall basket needs an espresso-capable grinder for reliable control. A pressurised basket can work with suitable pre-ground coffee, although grinding immediately before brewing gives you more flexibility.
How hard should I tamp?
Tamp firmly enough to compress the coffee and keep the surface level. You do not need to reproduce an exact force number; once the puck stops compressing, applying much more pressure is not the useful variable.
Should espresso always take 25–30 seconds?
No. That is a common starting window, not a universal requirement. The timing method, dose, output, basket and coffee all affect the useful range. Compare measured shots and choose the recipe that tastes best.
Does thick crema mean the espresso is good?
Not necessarily. Crema is affected by coffee age, roast, species and basket design. Pressurised baskets can create abundant foam, while a balanced single-wall extraction can have less crema.
Why does the setting change with a new bag of coffee?
Different coffees grind and resist water differently, and the same coffee changes as it ages. Begin near the previous setting, pull a measured shot and make a small adjustment from the result.
How long does it take to learn espresso?
There is no reliable fixed timetable. Most people improve quickly once they weigh the dose and output and change one variable at a time, but consistency depends on the machine, grinder, basket and how often they practise.
How should I clean up after making espresso?
Discard the puck, rinse the basket and accessible coffee-contact surfaces, and purge and wipe the steam wand immediately after milk. Follow the machine’s own deeper cleaning and descaling programmes separately.
