Getting the perfect cup of coffee starts with the right grind, especially when using a machine like the ENA Micro 90. This compact espresso maker demands a specific grind size to unlock its full flavor potential. If your grind is too coarse or too fine, you’ll end up with a brew that’s either weak or bitter.
Understanding what grind works best for the ENA Micro 90 helps you take control of your coffee experience. Whether you’re a seasoned barista or just starting out, knowing the ideal grind size ensures every shot is smooth and balanced. Let’s dive into what grind of beans suits this machine perfectly and how it affects your daily cup.
Understanding the Ena Micro 90 Coffee Machine

Importance of Bean Grind Size
Using the correct grind size aligns with the Ena Micro 90’s extraction pressure and flow rate. Finer grinds increase surface area, slowing pressure to enhance flavor extraction but risk over-extraction if too fine. Coarser grinds speed pressure flow, producing under-extracted and weak coffee if too coarse. The Ena Micro 90’s built-in grinder adjustment accommodates this balance, allowing medium-fine grind settings as ideal for its espresso process. Matching grind size to machine specs prevents bitterness and ensures rich, full-bodied espresso.
What Grind of Beans Works Best in Ena Micro 90
Choosing the right grind size for your ENA Micro 90 unlocks its full espresso potential. The machine performs best with precise grind settings tailored to its fast extraction and pressure system.
Recommended Grind Settings
Set the ENA Micro 90 grinder between medium-fine and fine. The 12-step grinder offers control, but aim for a grind that feels slightly finer than table salt. Adjust within this range if the espresso tastes too bitter or weak. Finer than medium-fine risks over-extraction; coarser hampers shot richness. Regularly check grind consistency to maintain smooth extraction flow lasting 25-30 seconds.
How Grind Size Affects Coffee Flavor
Grind size impacts water flow, extraction time, and flavor balance in your espresso. Finer grinds increase surface area, slowing water passage and intensifying extraction. If too fine, extraction becomes bitter and harsh. Coarser grinds speed water flow, causing under-extraction and sour or thin taste. Medium-fine grinds balance sweetness, body, and acidity, matching the ENA Micro 90’s pressure and temperature control for full-bodied, flavorful shots.
Comparison: Fine vs. Medium vs. Coarse Grinds
| Grind Size | Extraction Speed | Flavor Outcome | ENA Micro 90 Suitability |
|---|---|---|---|
| Fine | Slow | Bitter, overpowering | Use sparingly; may clog or over-extract |
| Medium-fine | Moderate | Balanced, rich | Ideal; aligns with machine settings |
| Coarse | Fast | Thin, under-extracted | Not recommended; weakens espresso |
How to Adjust Grind Size for Ena Micro 90
Adjusting the grind size for your Ena Micro 90 controls extraction speed and flavor balance. This section helps you fine-tune your grind for optimal espresso quality.
Tips for Achieving the Perfect Grind
- Start with the medium-fine setting, falling between sugar and table salt texture.
- Adjust grind size in small increments to avoid over- or under-extraction.
- Use a consistent, burr grinder to maintain uniform particle size.
- Observe extraction time; 25 to 30 seconds indicates a proper grind.
- Taste your espresso; bitterness suggests a finer grind, sourness a coarser one.
- Clean your grinder regularly to prevent stale residue affecting the grind.
Using Different Grinders with Ena Micro 90
- Burr grinders provide consistent particle size and are recommended for Ena Micro 90.
- Blade grinders may produce uneven grinds, impacting extraction negatively.
- Automatic built-in grinders in Ena Micro 90 allow 12-step adjustments for precision.
- Manual grinders require patience but can achieve fine-medium settings with practice.
- When switching grinders, recalibrate grind size and extraction time to maintain balance.
Common Issues with Incorrect Grind Size
Using the wrong grind size in your ENA Micro 90 leads to common problems that affect espresso quality. Identifying these issues helps you adjust the grind to improve flavor and extraction.
Under-Extraction and Over-Extraction Problems
Under-extraction occurs when the grind is too coarse, causing water to flow through quickly and extracting insufficient coffee compounds. You’ll notice sour, weak, or watery espresso with a thin body. Over-extraction happens when the grind is too fine, slowing water flow and drawing out bitter, harsh flavors and excessive bitterness. Your espresso may taste burnt or overly astringent with an unpleasant aftertaste. Both extremes disrupt the balance of acidity, sweetness, and bitterness critical to the ENA Micro 90’s designed extraction parameters.
How to Troubleshoot Grind-Related Issues
Start by observing your espresso’s shot time. If extraction finishes significantly faster than 25 seconds, your grind is too coarse. Adjust finer in small increments and test again. If extraction takes longer than 30 seconds with bitter flavors, coarsen the grind slightly. Use the ENA Micro 90’s 12-step grinder for precise adjustments. Taste every pull to monitor changes in body and flavor balance. Consistent grind size from a burr grinder reduces variability and helps maintain optimal extraction. If switching grinders, recalibrate grind settings and extraction times before brewing.
Conclusion
Getting the grind size right for your ENA Micro 90 makes all the difference in your espresso’s flavor and texture. By dialing in a medium-fine grind, you’ll unlock the machine’s full potential and enjoy a balanced, rich cup every time. Remember, small adjustments and consistent grinding go a long way toward perfecting your brew.
Stay attentive to how your espresso tastes and flows, and don’t hesitate to tweak your grind as needed. With a bit of practice, you’ll master the grind settings that suit your preferences and the ENA Micro 90’s capabilities perfectly. Your ideal espresso is just a grind away.
