Dialing in espresso on a DF54 or DF64 Gen 2 doesn't need to be complicated. Although espresso recipes can involve grind settings, shot times, brew ratios and temperatures, most home baristas can begin with one simple, repeatable process.
Quick method: Keep your dose fixed, choose a target yield, grind finer if the shot runs too quickly, grind coarser if it runs too slowly, and use taste—not shot time alone—to make the final decision.
For most home espresso setups, dialling in can be reduced to four steps:
- Keep your coffee dose consistent.
- Choose a target espresso yield.
- Adjust the grind until the shot flows reasonably.
- Use taste to refine the final recipe.
The same general method applies to both the DF54 Coffee Grinder and the DF64 Gen 2. The exact setting and flavour profile will vary with the burr geometry, grinder calibration, coffee and espresso setup.
What Does Dialling In Espresso Mean?
Dialling in means adjusting your espresso recipe until the coffee tastes balanced and enjoyable.
Grind size is one of the main factors controlling how quickly water can pass through the coffee bed:
- A finer grind creates more resistance and will normally slow the shot down.
- A coarser grind creates less resistance and will normally allow the shot to run faster.
Dose, basket size, puck preparation, espresso-machine pressure and channeling can also affect the flow. This is why dialling in should involve more than simply copying someone else’s grinder setting.
The correct setting changes depending on the coffee, its freshness, roast level, dose, basket, espresso machine, burr type and grinder calibration. The numbers on the grinder are therefore best treated as reference points rather than fixed recipes.
Our DF54 grind-setting guide and DF64 Gen 2 grind-size guide can help you find an approximate starting range. From there, use the process below to make the final adjustments.
Step 1: Keep Your Coffee Dose Consistent
Begin by choosing a dose that suits your portafilter basket.
For example:
- Weigh 18 grams of whole coffee beans.
- Grind the full dose.
- Distribute and tamp the coffee consistently.
- Repeat with the same 18-gram dose while dialling in.
The exact dose doesn't have to be 18 grams. A smaller basket may work better with 16 grams, while a larger basket may be designed for 20 grams or more.
What matters is that you avoid changing the dose and grind setting at the same time. If several variables change between shots, it becomes difficult to identify what improved—or worsened—the result.
Step 2: Choose a Starting Brew Ratio
Brew ratio describes the relationship between the dry coffee dose and the amount of liquid espresso produced in the cup.
A common starting point is a 1:2 ratio.
For example:
- 18 grams of coffee in
- 36 grams of espresso out
Place a scale beneath your cup and stop the shot when the espresso reaches the target weight. A compact scale such as the Grind Logic Mini Espresso Scale can help you measure shot weight and time consistently.
This gives you a repeatable endpoint. Rather than judging the shot by volume or by how full the cup appears, you can compare each attempt using the same dose and yield.
A 1:2 ratio is only a starting point. Different coffees may taste better with a shorter or longer ratio.
Light-roast espresso may work better at a longer ratio
Lightly roasted coffees can sometimes taste sharp, sour or overly concentrated when brewed at a traditional 1:2 ratio.
Instead of immediately grinding much finer, try allowing more espresso into the cup:
- 18 grams in and 45 grams out is a 1:2.5 ratio.
- 18 grams in and 54 grams out is a 1:3 ratio.
A longer ratio can increase extraction and help bring out more sweetness, while making bright acidity feel more integrated. It will also produce a less concentrated espresso with a lighter body.
Medium and darker roasts will often work well closer to 1:2, although the best ratio will depend on the coffee and your preferences.
Step 3: Pull a Shot and Observe the Flow
Once your dose and target yield are fixed, pull your first shot.
Shot time is useful, but it should be treated as a diagnostic clue rather than an absolute measure of quality. As an initial reference, many espresso recipes fall somewhere around 25–35 seconds, although pre-infusion and machine design can affect how the time is measured.
For consistency, begin timing when the pump or pre-infusion starts, and use the same timing method for every shot.
The first question is whether the shot is running much too quickly or much too slowly.
If the shot runs too quickly
The espresso may reach your target yield very rapidly and flow thinly from the portafilter.
The coffee may taste:
- sour or sharply acidic;
- thin or watery;
- weak; or
- lacking in sweetness.
Provided your dose and puck preparation are consistent, move the grinder slightly finer and try again.
On both the DF54 and DF64 Gen 2, lower dial numbers generally correspond to finer settings.
If the shot runs too slowly
The machine may struggle to produce espresso, the flow may reduce to slow drips, or the shot may take an unusually long time to reach the target yield.
The coffee may taste harsh, bitter, dry or astringent. In some cases, an excessively fine grind can also encourage uneven flow or channeling, producing a shot that tastes both sour and harsh.
Move the grinder slightly coarser and try again. Also check that the grounds are distributed evenly and the puck is tamped level.
Higher dial numbers generally correspond to coarser settings.
Step 4: Make Small Grind Adjustments
Both the DF54 and DF64 Gen 2 use stepless grind adjustment. This allows precise changes, but it also means that you do not need to move from one whole number to another.
Once you are reasonably close, make small movements between the numbered markings.
- Make a larger adjustment when the shot is clearly much too fast or almost completely stalled.
- Make a very small adjustment when the shot is close but still needs refinement.
- Pull another shot before making a second change.
Avoid repeatedly moving finer and coarser without testing the result. A deliberate, one-change-at-a-time process will usually reach a suitable setting with less wasted coffee.
Moving the grinder to a finer setting
When moving towards a finer setting, make the adjustment while the grinder is running. This helps clear residual coffee as the space between the burrs becomes smaller.
Moving coarser separates the burrs and can usually be done while the grinder is stopped, although making all adjustments while the grinder runs is a simple and consistent workflow for DF grinders.
Never force an adjustment collar that feels unusually stiff.
If the dial becomes difficult to move:
- Move it slightly coarser.
- Run the grinder briefly.
- Try the finer adjustment again while the grinder is running.
For more information about safe adjustment and routine grinder care, see our DF54 and DF64 Gen 2 cleaning and maintenance guide.
Step 5: Use Taste to Make the Final Decision
Shot time helps you enter a sensible range, but taste should determine the final recipe.
A shot can run for exactly 30 seconds and still taste unpleasant. Another may fall outside the conventional time range but taste balanced and enjoyable.
Once the espresso is flowing reasonably, ask:
- Is the acidity pleasantly bright, or sharply sour?
- Is there noticeable sweetness?
- Does the coffee taste thin or hollow?
- Is the finish clean, or dry and harsh?
- Are the flavours clear, or does everything taste muddled?
| What you observe | Likely next step |
|---|---|
| Shot runs quickly and tastes sour or thin | Grind slightly finer |
| Shot runs slowly and tastes bitter or dry | Grind slightly coarser and check puck preparation |
| Shot tastes sour or underdeveloped but the flow looks reasonable | Try a slightly longer yield |
| Shot tastes thin or weak after extending the yield | Shorten the yield; if it remains sour, grind slightly finer |
| Shot tastes harsh, dry or overly intense | Grind slightly coarser or shorten the yield |
| Shot tastes both sour and harsh | Check distribution and tamping, then try a slightly coarser grind |
| Shot tastes sweet, balanced and enjoyable | Keep the recipe |
Do Not Chase Someone Else’s Exact Grind Setting
Two DF54 or DF64 Gen 2 grinders may not use precisely the same number for the same coffee.
The apparent setting can vary because of:
- the grinder’s zero point;
- burr calibration and alignment;
- burr type and geometry;
- coffee freshness and roast level;
- dose and basket size;
- espresso-machine pressure and temperature; and
- puck preparation.
A recommended setting can help you enter the correct general range, but your own shot flow and taste provide better information than another person’s dial number.
It's also normal to make small adjustments as coffee ages. Many coffees gradually require a slightly finer setting to maintain the same flow, but use the behaviour and taste of the shot rather than assuming that every coffee will change in exactly the same way.
Burr geometry can also affect clarity, body and the way an espresso extracts. You can learn more in our guide to Red Titanium burrs. DF54 owners can also explore our 54mm flat burr options, while DF64 Gen 2 owners can browse our SSP 64mm burr range.
What If Your Espresso Shots Are Inconsistent?
If one shot runs quickly and the next runs slowly despite using the same grind setting, grind size may not be the main problem.
Check that you are:
- weighing the same dose each time;
- distributing the grounds evenly;
- tamping level;
- using the same target yield;
- using the same timing method;
- allowing the espresso machine to reach a stable temperature; and
- keeping the grinder’s exit chute reasonably clear.
Channeling occurs when water finds an easier path through part of the coffee bed. It can cause uneven extraction and make a suitable grind setting appear too coarse. Changing the grinder repeatedly will not necessarily solve inconsistent puck preparation.
A Simple Espresso Dial-In Example
Suppose you begin with:
- 18 grams of coffee;
- a target yield of 36 grams; and
- an approximate DF54 or DF64 espresso-range setting.
Your first shot reaches 36 grams in 17 seconds and tastes thin and sour.
Move the grinder finer.
The second shot reaches 36 grams in 27 seconds. The flow looks better, but a light-roast coffee still tastes sharply acidic.
Instead of continuing to grind finer until the machine begins to choke, allow the shot to run to 45 grams.
If the longer shot tastes sweeter and more balanced, your final recipe might be:
- 18 grams of coffee in;
- 45 grams of espresso out;
- approximately 30 seconds; and
- the grind setting used for the second shot.
That is a successfully dialled-in espresso, even though it does not follow a strict 1:2 recipe.
The Simple DF54 and DF64 Dial-In Method
Keep the dose fixed. Choose a target yield. Use grind size to control the flow. Use taste to choose the final recipe.
Make one deliberate change at a time, record the recipe that works, and expect to make occasional small adjustments when changing coffees or as a bag ages.
DF54 and DF64 Gen 2 Dial-In FAQs
What grind setting should I start with for espresso?
There is no single espresso setting that will work for every DF54 or DF64 Gen 2. The correct setting depends on the grinder’s zero point, burr calibration, coffee, dose, basket and espresso machine.
Use our DF54 grind-setting guide or DF64 Gen 2 grind-size guide to find an approximate starting range, then adjust according to shot flow and taste.
Should I adjust grind size, dose or yield first?
While initially dialling in, keep your dose and target yield consistent and adjust the grind size first. This makes it easier to understand what each adjustment has changed.
Once the shot is flowing within a reasonable range, use taste to decide whether a small change to the yield would improve the result. For example, a light-roast coffee that still tastes sharply acidic may benefit from a slightly longer yield.
Why is my espresso shot running too quickly?
If the dose and puck preparation are consistent, a shot that reaches its target yield too quickly will normally need a finer grind setting. Move the DF54 or DF64 Gen 2 slightly finer while the grinder is running, then pull another shot.
If shot times vary significantly without changing the grinder, also check that you are using the same dose, distributing the grounds evenly and tamping level.
Why is my espresso shot running too slowly?
A shot that drips slowly, stalls or takes an unusually long time to reach its target yield will normally need a slightly coarser grind setting.
Also check that the basket has not been overfilled and that your grounds are distributed evenly. An excessively fine grind or uneven puck can encourage channeling and produce espresso that tastes both sour and harsh.
Does espresso have to take 25 to 35 seconds?
No. A shot time of approximately 25–35 seconds is a useful starting reference, not a strict rule. Pre-infusion, basket design, coffee, burr geometry and espresso-machine settings can all affect the ideal shot time.
Use the same timing method for each shot and make the final decision based on taste. A balanced shot outside the conventional time range is preferable to an unpleasant shot that happens to take exactly 30 seconds.
Should I adjust my DF54 or DF64 Gen 2 while it is running?
When moving towards a finer setting, make the adjustment while the grinder is running. This helps clear coffee from between the burrs as the space between them becomes smaller.
Moving coarser can usually be done while the grinder is stopped, although making all adjustments while it runs is a simple and consistent workflow. Never force an adjustment collar that feels unusually stiff.
Why does my grind setting differ from someone else’s?
Grind-setting numbers are reference points rather than universal measurements. Two DF54 or DF64 Gen 2 grinders may use different settings for the same coffee because of differences in zero point, burr calibration, burr geometry, coffee freshness, dose, basket and espresso machine.
Use someone else’s setting only as an approximate starting point. Your own shot flow and taste are more useful than matching their exact dial number.
How often should I redial my espresso grind?
You should expect to make small adjustments when changing coffees and sometimes as the same bag ages. Many coffees gradually require a slightly finer setting to maintain a similar flow, although the amount and direction of adjustment can vary.
You do not need to begin the entire process again. Start from your previous setting and make one small adjustment at a time.
