This guide walks you through how to dial in espresso on a Eureka Mignon (step-by-step), covering:
- Setting your initial grind parameters
- Evaluating extraction quality through taste and visual cues
- Making precise adjustments until you hit that sweet spot
- Maintaining consistency once you’ve nailed your settings
By the end, you’ll have the confidence to pull consistently excellent shots that keep customers coming back.
Understanding Your Eureka Mignon Grinder
The Eureka Mignon range offers several models tailored to different espresso needs, each bringing distinct advantages to your dialling-in process. The Specialita features 55mm flat burrs and a stepless adjustment system, making it ideal for precise grind changes during dialling in. The Turbo model steps up with 65mm burrs, delivering faster grinding speeds whilst maintaining exceptional grind consistency—particularly valuable in busy café environments where you’re pulling multiple shots throughout the day.
How Burr Size Affects Your Espresso Quality
Burr size directly impacts your espresso quality in two key ways:
- Larger burrs (like those in the Turbo) generate less heat during grinding, preserving delicate aromatics in your beans.
- They also produce a more uniform particle distribution, which translates to cleaner, more balanced extractions.
The flat burr design across all Eureka Mignon models creates a bimodal particle distribution—meaning you get both fine particles for body and slightly larger ones for clarity, resulting in espresso with excellent texture and definition.
The Importance of Grind Consistency
Grind consistency sits at the heart of successful espresso extraction. When your Eureka Mignon produces uniform particles, water flows through the coffee puck evenly, extracting flavours at the same rate. This consistency manifests in your cup as:
- Balanced flavour profiles – sweetness, acidity and body appear in harmony rather than one dominating
- Predictable shot timings – consistent grinds mean your 25–30 second extraction window becomes reliable
- Repeatable results – once dialled in, you’ll pull identical shots throughout service
Inconsistent grinds create channelling, where water finds paths of least resistance through your puck. This leads to simultaneous under-extraction (sour notes) and over-extraction (bitterness) in the same shot—a frustrating outcome that no amount of technique can remedy without addressing the grind itself.
Enhancing Your Espresso Experience
To enhance your espresso experience further, consider integrating high-quality coffee products into your routine such as Douwe Egberts Pure Gold Sticks, known for their medium-bodied, well-balanced flavour and aroma.
Moreover, ensuring an efficient cleanup process post-extraction can significantly improve workflow in a busy café setting. A product like the RhinoWare Deluxe Knock Box could be an invaluable addition to your coffee setup.
For achieving consistent extraction performance across various brew methods, consider using specialised equipment such as the VST Precision Ridgeless Filter Basket. This filter basket is designed to deliver optimal extraction while minimising sediment.
Lastly, if you’re looking to expand your coffee-making arsenal beyond just grinding and brewing, you might want to explore options like the Eureka Pura Espresso Machine. This machine combines elegance with practicality and is designed for both prosumer and professional markets.
Preparing to Dial In Your Espresso
Proper espresso preparation starts well before you touch the grind adjustment dial. A methodical grinder setup ensures you’re working with a clean slate, allowing you to make accurate adjustments without interference from previous sessions.
Start with a Spotless Grinder
Old coffee residues clinging to your burrs and chute can dramatically skew your dial-in results. Stale grounds mixed with fresh beans create inconsistent flavour profiles that make it impossible to judge whether your adjustments are actually working. Before beginning your dial-in session, remove the hopper and purge any remaining beans. Use a soft brush to sweep away grounds from the burr chamber, paying particular attention to the areas around the adjustment collar where coffee oils tend to accumulate.
For a deeper clean grinder routine, consider running grinder cleaning tablets through your Eureka Mignon monthly—ADS Coffee Supplies stocks Puly Grind tablets specifically designed for this purpose.
Essential Setup Checks
Your Eureka Mignon needs proper configuration before you start testing shots:
- Hopper position: Ensure the bean hopper sits securely in place with no gaps that could allow moisture in
- Burr alignment: Check that the adjustment collar moves smoothly without grinding or catching
- Dosing chamber: Verify the grounds exit cleanly into your portafilter without bridging
Tools That Make the Difference
Accurate espresso preparation demands precision measuring equipment. A digital scale capable of 0.1g accuracy lets you track dose consistency shot-to-shot. A dosing cup catches grounds cleanly, reducing mess and waste. For initial testing, choose medium-roasted single-origin beans with a roast date within two weeks—fresher beans respond more predictably to grind adjustments.
To enhance your espresso experience further, consider exploring other products offered by ADS Coffee Supplies. They provide an array of tools such as scales and dosing cups that are perfect for dialling in your Eureka Mignon. Additionally, they offer a curated selection of espresso beans which can significantly improve your brewing results.
Moreover, if you’re interested in diversifying your beverage offerings beyond just coffee, ADS Coffee Supplies has a variety of other products that might catch your interest. For instance, they have delicious Shmoo milkshake powder which can elevate your milkshake experience. They also stock Teapigs Super Fruit Tea Temples, known for their super fruity blend that tastes as great as it smells.

Step 1: Selecting the Initial Grind Setting
Choosing your starting point for dialing in sets the foundation for the entire process. The Eureka Mignon’s stepless adjustment mechanism allows for precise control, but knowing where to begin saves time and coffee.
For medium to dark roasts, start with a finer initial grind setting—typically around the 2-3 mark on most Eureka Mignon models. These beans are more soluble and extract flavour compounds more readily, requiring less surface area exposure. Light roasts, being denser and less soluble, benefit from a slightly coarser starting position around 3-4 to prevent channeling whilst still achieving proper extraction.
The relationship between coarse vs fine grind directly impacts your espresso’s character:
- Finer grinds increase extraction time (typically 28-35 seconds), producing fuller body and richer sweetness but risking bitterness if pushed too far
- Coarser grinds speed up extraction (20-25 seconds), resulting in brighter acidity and lighter body, though under-extraction brings unwanted sourness
Your desired flavour profile guides this choice. Seeking chocolate notes and syrupy texture? Start finer. Prefer fruit-forward brightness with tea-like clarity? Begin slightly coarser.
Record your initial grind setting number before pulling your first shot. This reference point becomes invaluable when making micro-adjustments, particularly when switching between different coffee beans or adjusting for ambient humidity changes that affect grind consistency.
To further enhance your coffee experience, consider exploring some of the seasonal drink options available at ADS Coffee Supplies. As we cosy up to autumn, it’s the perfect time to switch up your current drinks list and add warming, indulgent drink options such as Chai, Cinnamon, Pumpkin Spice, or Winter-themed flavours.
Moreover, if you’re looking for convenience in serving a wide variety of drinks from black coffee and cappuccino to cold or hot lattes, the Douwe Egberts Cafitesse Hot ‘n’ Cold machine could be a perfect companion for busy breakfast buffets or conferences.
Lastly, don’t forget about the importance of maintaining your equipment for optimal performance. A polyester pot brush can be an essential tool in keeping your coffee-making equipment clean and efficient.
Step 2: Pulling Your First Shot
With your initial grind setting selected, it’s time to extract your first espresso shot and gather the data you’ll need for adjustment. Start by dosing your ground coffee into the portafilter—most espresso recipes call for 18–20g of coffee, though this can vary based on your basket size and preference.
Distribute the grounds evenly in the basket using a distribution tool or by tapping the portafilter gently, then tamp with consistent pressure (around 15kg of force). Lock the portafilter into your machine and place a shot glass on a digital scale beneath the spouts. Zero the scale, then start your timer simultaneously as you begin extraction.
Measuring Your Results
Shot timing typically aims for 25–30 seconds from the moment you press the brew button until you stop the shot. Watch the scale to track your yield measurement—you’re generally targeting a 1:2 ratio, so 18g of coffee should produce approximately 36g of liquid espresso.
Note both figures carefully:
- Time: How many seconds from start to finish?
- Yield: What weight of espresso did you extract?
- Flow rate: Did the espresso pour steadily or too fast/slow?
These measurements form your baseline for the adjustments you’ll make next. Keep a notepad handy or use your phone to record these numbers—they’re essential for tracking your progress through the dial-in process.
Step 3: Evaluating Espresso Taste and Extraction
Once you’ve pulled your first shot, it’s time for the crucial espresso tasting and extraction evaluation phase. This sensory assessment determines whether your grind setting needs adjustment.
Assessing Flavour Balance
Take a moment to taste your espresso, paying attention to three key elements:
- Sweetness – A well-extracted shot should have natural sweetness, even without sugar
- Acidity – Bright, pleasant acidity adds complexity and liveliness
- Bitterness – Some bitterness is desirable, but it shouldn’t dominate
The ideal shot achieves harmony between these three components. If one element overpowers the others, you’ll need to adjust your grind.
Identifying Under-Extraction
Under-extracted espresso typically presents these characteristics:
- Sharp, sour or vinegary taste
- Thin, watery body
- Pale, quickly dissipating crema
- Shot flows too quickly (under 20 seconds)
Spotting Over-Extraction
Over-extracted espresso shows different warning signs:
- Harsh, ashy or burnt bitterness
- Dry, astringent mouthfeel
- Dark crema with a grey ring around the edge
- Shot drips slowly or chokes (over 35 seconds)
Visual Cues for Crema Quality
Excellent crema quality indicates proper extraction. Look for a thick, golden-brown layer with fine bubbles that persists for several minutes. The crema should have a tiger-striped appearance as it flows into your cup, suggesting balanced extraction throughout the shot.
Enhancing Your Espresso Experience
If you find your espresso lacking in sweetness or depth of flavour, consider experimenting with different additives. For instance, you could try incorporating some Simply Luxury Gold Chocolate Powder into your drink. This beautifully balanced chocolate powder blend can enhance the overall flavour profile of your espresso.
Moreover, to ensure you’re using quality water for brewing—an often overlooked aspect of making great coffee—consider using the IEN 3000 Complete Filter with Head. This filter helps prevent scale build-up and maintains stable pH levels in your water, which can significantly improve the extraction process and ultimately the taste of your espresso.
Step 4: Adjusting Grind Size Based on Results
Now that you’ve evaluated your shot, it’s time to make targeted adjustments to your Eureka Mignon’s grind setting. The key to successful extraction optimisation lies in understanding which direction to move.
When your shot tastes sour or runs too quickly (under 25 seconds)
You need a finer grind. Turn your adjustment collar clockwise in small increments—typically just a quarter turn or less. This increases resistance, slowing water flow through the coffee puck and allowing more time for proper extraction.
When your shot tastes bitter or runs too slowly (over 35 seconds)
You need a coarser grind. Turn the collar anti-clockwise by the same small amount. This reduces resistance and speeds up extraction, preventing over-extraction of unpleasant compounds.
The relationship between finer grind vs coarser grind might seem straightforward, but the impact is dramatic. A single notch on your Eureka Mignon can shift your shot time by 3–5 seconds and completely transform the flavour profile. This is why precision matters during grind adjustment.
Critical tip: Make only one small adjustment at a time. Resist the temptation to make large changes, even if your first shot was far from ideal. Each adjustment should be followed by another test shot to accurately track the effect. This methodical approach prevents overshooting your target and wasting coffee during the dial-in process.
Step 5: Repeating the Process Until Optimal Dial-In is Achieved
The iterative dialing in process requires patience and systematic tracking. After making each grind adjustment, pull another shot immediately and record your observations. This methodical approach prevents confusion when multiple variables—like machine temperature or bean freshness—might be shifting simultaneously.
Keep a simple log noting:
- Grind setting number
- Shot time (aim for 25-30 seconds typically)
- Yield weight (usually 1:2 ratio, so 18g in, 36g out)
- Taste notes (balance of sweet, sour, bitter)
Consistency testing becomes crucial at this stage. Once you’ve found a setting that produces a balanced, enjoyable shot, pull at least three consecutive shots without changing anything. This verifies your grind setting works reliably rather than being a lucky one-off.
Temperature stability matters here—wait 30 seconds between shots to let your machine recover. If all three shots taste similar and extract within your target window, you’ve successfully dialled in.
Document your final setting clearly. Many Eureka Mignon users photograph their grind dial position or note the exact number. Bean age affects extraction speed, so expect to make minor tweaks (usually 1-2 clicks) as your coffee ages beyond 7-10 days post-roast. Fresh beans from ADS Coffee Supplies typically maintain consistency for 2-3 weeks when stored properly in airtight containers.
While you’re perfecting your coffee-making skills with these fresh beans, you might also consider exploring other areas of the beverage industry. For instance, if you’re interested in expanding your offerings to include milkshakes, ADS Coffee Supplies also provides all-in-one milkshake machine packages including mixers, cups & flavourings which are ideal for new businesses looking to diversify their product range.
Tips for Maintaining Consistency with Your Eureka Mignon Grinder After Dialling In Successfully!
You’ve nailed your perfect dial-in settings, but keeping those consistent espresso shots flowing requires proper grinder maintenance. The precision of your Eureka Mignon, which can only be maintained through regular care, is essential to prevent coffee oils and residue from affecting your carefully calibrated grind.
Daily and Weekly Maintenance Schedule
- Daily purging: Run a small amount of beans through after each dial-in session to clear any retention.
- Weekly hopper cleaning: Remove the bean hopper and wipe down with a dry cloth to prevent oil build-up.
- Bi-weekly burr brushing: Use a dedicated grinder brush to sweep away coffee particles from the burr chamber.
Burr Cleaning Techniques Specific to Eureka Mignons
The stepped adjustment collar on your Eureka Mignon makes deep cleaning straightforward. Remove the hopper, then the upper burr carrier by turning it anticlockwise. Brush both burrs thoroughly, paying attention to the grooves where oils accumulate. For stubborn residue, consider using professional grinder cleaning tablets from ADS Coffee Supplies, which help break down stubborn residue without damaging the burrs.
Monthly Deep Clean Protocol
Set aside 30 minutes monthly for a complete disassembly and clean. This prevents the gradual drift in grind consistency that occurs when oils coat the burrs. Vacuum the grind chamber and wipe all surfaces with a slightly damp cloth, ensuring everything dries completely before reassembly.
A well-maintained Eureka Mignon delivers consistent espresso shots over time, protecting your investment in both equipment and the perfect dial-in you’ve achieved. However, if you ever want to switch things up from coffee to tea, remember that ADS Coffee Supplies also offers quality products like PG Tips Enveloped Tea Bags and Teapigs Everyday Brew Tea Temples which could complement your beverage choices nicely.
Advanced Dialling In Techniques for Experienced Users Who Want To Take Their Skills To The Next Level!
Once you’ve mastered the basics of advanced espresso dialling in methods beyond just adjusting grind size, you can explore variables that transform good espresso into exceptional shots.
Dose Adjustment Strategies
Dose adjustment strategies coupled with precise grinding techniques allow you to manipulate extraction without touching your grind setting. Increasing your dose by 0.5–1g whilst maintaining the same grind creates a denser puck, extending contact time and intensifying body. Decreasing dose speeds extraction, highlighting brighter acidity. This approach works brilliantly when switching between different roast profiles on your Eureka Mignon.
Tamping Pressure Experiments
Tamping pressure variation experiments paired with dialled-in settings reveal subtle flavour shifts. Whilst consistency matters most, testing pressures between 10–15kg can alter flow resistance. Lighter pressure (10kg) produces faster shots with enhanced clarity, whilst firmer tamping (15kg) slows extraction for richer sweetness. Use a calibrated tamper to maintain repeatability.
Distribution Techniques
Pre-infusion timing adjustments on compatible machines paired with your Eureka Mignon’s precise grind create layered complexity. Experiment with 3–8 second pre-infusion periods to see how gentle saturation affects extraction evenness. WDT (Weiss Distribution Technique) tools break up clumps before tamping, eliminating channeling that undermines your carefully dialled settings.
Additionally, understanding the proper way to grind coffee beans for full flavor and no bitterness is crucial in this process. For more insights on espresso making and advanced techniques, you may want to explore resources like those found on Decent Espresso’s blog.
