Details Product Specs
Built for the craft. Finished in black.
Most home grinders make you choose: espresso precision or brewing versatility. The H64 gives you both. Designed by Ascaso in Barcelona and built with the same flat burr geometry used in café grinders, the H64 delivers consistent, uniform particle size from fine espresso all the way to coarse cold brew - without noise, without mess, and without a learning curve.
Program up to three timed doses for your morning espresso routine, or switch to single-dose mode when you're dialing in a pour-over. The stepless micrometric adjustment ring gives you infinite control between grind settings, so you're never locked into a preset notch when you need to fine-tune. At just under 14 inches tall and finished in a bold matte black, it's a grinder that earns its place on the counter - and looks the part.

Who the H64 Grinder is For
The H64 is for the home barista who has outgrown entry-level grinders and wants professional results without stepping up to a commercial machine. It's a strong fit if you:
- Pull espresso daily and want a reliable dose-to-dose consistency without constant weighing.
- Brew across multiple methods - espresso in the morning, pour-over on weekends - and want one grinder that handles both well.
- Live with someone who doesn't want to hear the grinder at 6am.
- Are upgrading from a stepped-adjustment grinder and want the freedom of true stepless dialing.
- Value thoughtful industrial design and want something that looks as good as it performs.
It's not the right fit if you're only brewing drip or French press and don't need espresso capability, a simpler grinder will serve you fine at a lower price point.
How it Compares to Other Grinders
H64 vs. Baratza Encore ESP
The Encore ESP is one of the best entry-level espresso grinders on the market, but it's a 40mm conical, with stepped adjustments and a smaller motor. The H64's 64mm flat burrs and stepless ring are a meaningful upgrade in grind uniformity and adjustment precision. If you're serious about espresso and plan to stick with it, the H64 is the better long-term investment.
H64 vs. Mahlkönig X64 SD
Both run 64mm flat steel burrs and cover the full range from espresso to cold brew, so this is a genuine head-to-head on burr spec. The real difference is workflow philosophy. The X64 SD is built around single-dose grinding: zero retention, a bellow for clean purging, and anti-popcorning technology for consistent feeding. It's purpose-built for the barista who grinds fresh per cup and switches beans often. It includes a small hopper extension for added capacity, but there are no programmable timed dose presets. The H64 gives you single-dose capability when you want it, plus a 300g hopper and three programmable dose presets when you don't. For home baristas who want flexibility across workflows - not just freshness optimization - the H64 delivers comparable burr performance at a meaningfully lower price.
H64 vs. Fiorenzato Allground Sense
The Allground Sense is the tech-forward option in this category; it adds Bluetooth connectivity and a built-in scale for dose-by-weight grinding, which is genuinely useful if you want a fully automated, scale-free workflow. You're paying for that technology, though, and the 54mm burrs are smaller than the H64's 64mm. If smart features matter to you, the Sense earns its premium. If you'd rather have larger burrs and programmable timed doses without the app dependency, the H64 is the stronger value.
Key Takeaway
The H64 is the rare home grinder that doesn't ask you to choose between espresso precision and brewing versatility - it handles both, seriously. With 64mm flat burrs (the largest in its competitive set), a stepless micrometric adjustment ring, and a motor built for quiet daily use, it delivers professional-grade performance in a counter-friendly footprint. Programmable timed dosing keeps your espresso routine fast and repeatable; single-dose mode keeps your pour-over fresh. And because Espresso Parts is the U.S. Ascaso distributor, you're buying with full parts and warranty support behind it. At its price point, the H64 competes with grinders that cost noticeably more - and holds its own.
Why Espresso Parts Recommends the H64
We've spent over 20 years helping home baristas and coffee professionals find the right equipment, and as the exclusive U.S. distributor for Ascaso, we know this brand's lineup as well as anyone.
The H64 earns our recommendation for a specific reason: it's one of the few home grinders that genuinely doesn't ask you to compromise. Flat burr grinders at this price usually cut corners somewhere: motor power, adjustment precision, or build quality. Ascaso didn't. The 64mm steel burrs, 280W motor, and full aluminum housing are all the real thing, not spec sheet window dressing.
We also recommend it because it's backed. As the U.S. distributor, we stock parts, support warranty claims, and can actually help when something goes wrong, which, with Ascaso equipment, is rare, but important to have covered.
If you're ready to move beyond entry-level grinding and want a machine that will grow with your skills, the H64 is where we'd point you.
FAQs
Q: Is the Ascaso H64 good for espresso?
A: Yes, it's built for it. The 64mm flat burrs and stepless micrometric adjustment give you the precision espresso dialing requires, and the programmable timed dosing makes your morning routine repeatable without a scale every pull. It's one of the strongest espresso-capable grinders at its price point.
Q: Can I use the H64 for pour-over and other brew methods?
A: Absolutely. That's the point of the "all-purpose" designation. Switch to single-dose mode, load only what you need, and the stepless adjustment dials all the way out to coarse settings for French press or cold brew. Most grinders in this class are espresso-optimized with brew method as an afterthought; the H64 handles both seriously.
Q: What does "stepless micrometric" adjustment mean?
A: Stepless means there are no preset notches or clicks: you turn the ring continuously to any position between fine and coarse. Micrometric means the adjustment is fine-grained and precise. For espresso, this matters a lot: the difference between over- and under-extracted can be a fraction of a millimeter of burr gap, and stepless adjustment lets you find exactly the right setting.
Q: How loud is the H64?
A: Significantly quieter than most home grinders at this burr size. Ascaso engineered the motor housing specifically for noise reduction. It's not silent, but it's quiet enough that most users describe it as non-disruptive in a home setting.
Q: What portafilter sizes does the adjustable holder fit?
A: The adjustable portafilter holder accommodates most standard home espresso portafilter baskets. If you have a less common basket size, contact us and we can confirm fit before you purchase.
Q: Does the H64 have a lot of grind retention?
A: Retention is modest for a hopper-fed flat burr grinder. The included blow-out hopper helps purge grounds between bean changes, and the single-dose mode minimizes the amount sitting in the grind path. For espresso workflows using the programmed doses, retention is consistent enough that it doesn't meaningfully affect shot-to-shot repeatability.
Q: What's included in the box?
A: The H64 ships with a blow-out hopper, dosing cup, and cup fork; everything you need to start grinding immediately for both portafilter and open-cup workflows.
Q: Does Espresso Parts carry Ascaso replacement parts?
A: Yes. As the U.S. Ascaso distributor, we maintain parts inventory and can support warranty service. If you have questions about parts availability, reach out to our team directly.
