Ascaso H64 Espresso Grinder

Description

Most grinders in the– range ask you to pick a side: espresso or filter, hopper-fed or single-dose. The Ascaso H64 refuses that compromise. Built around 64mm hardened flat steel burrs and a true stepless micrometric collar, it dials in with the surgical precision espresso demands — then opens all the way up to coarse filter and cold brew without breaking a sweat.

Add programmable dosing, a 60 dB noise profile quieter than most budget grinders, and a purpose-built anti-static system, and you have a machine that genuinely earns its place on a serious home bar.

64mm Hardened Flat Burrs

Burr diameter is the single biggest predictor of grind quality at a given price point — larger burrs move more coffee at lower RPM, generating less heat and more even particle distribution. At 64mm, the H64 punches well above its price class. The hardened steel construction holds its edge over years of daily use without the brittleness that plagues some ceramic alternatives. The result is a grind that’s consistent shot to shot, not just grinder-to-grinder on spec sheets.

True Stepless Adjustment — Dial In, Not Jump In

Stepped grinders give you predetermined click points. The H64’s stepless micrometric collar gives you infinite positions across the full grind range — from fine Turkish to coarse cold brew — so you can move in increments as small as the dial allows. For espresso, where the difference between a 25-second and 35-second shot can be a fraction of a turn, this matters more than any other spec on the sheet. The collar is firm and predictable, with no backlash or drift once set.

Three Programmable Doses Plus Manual Mode

The H64’s digital display and dosing system lets you store two timed doses for repeated workflows — single and double, or two different recipes — plus a third custom dose and an open-ended manual pulse mode for weighing into a cup. Once dialed, single-touch grinding keeps your morning routine consistent without fiddling. The display is clean and legible, and programming takes about thirty seconds to learn.

Hopper-Fed or Single-Dose — Your Workflow, Your Call

The H64 ships ready to run either way. Load the 300g hopper for back-to-back brewing — weekday mornings, hosting guests, grinding ahead for batch brew. Or remove the hopper and use the included bellows and mini-hopper for single-dose work: weigh your beans, drop them in, grind. The bellows clears most of the retained grounds between doses, making it genuinely usable as a single-dose platform rather than a retrofitted workaround.

Single-dose performance is strong for the price point. Retention runs approximately 0.5–1g under typical conditions — competitive at this tier, though dedicated single-dose grinders with RDT and WDT can push lower.

Who It’s For

Home baristas who’ve outgrown entry-level grinders and want to invest once rather than upgrade again in two years. The H64 is the kind of machine that holds its own as your espresso skills advance — and grows with you as you start exploring filter and cold brew alongside espresso.

Right for You If…

• You pull espresso at home daily and want consistent, repeatable results without the guesswork of a stepped grinder
• You want one grinder that does espresso, pour-over, and batch brew without buying multiple machines
• You’re upgrading from a conical burr grinder under and want a meaningful performance jump
• You value quiet operation — 60 dB keeps early-morning sessions from waking the house
• You want the flexibility to go single-dose some days and hopper-fed others

Things to Consider

• It’s a home grinder, not a commercial one. The H64 is designed and rated for home use by Ascaso. If you need a grinder pulling 50+ shots a day in a café, look at commercial options like the or .
• Single-dose retention is good, not perfect. Expect ~0.5–1g of retained grounds. If you’re obsessive about zero-retention workflows, look at grinders with purpose-built single-dose burr geometry — though you’ll pay more for it.
• No built-in scale. For consistent dosing by weight (recommended), you’ll want a separate 0.1g precision scale. We’re happy to recommend one — .

Anti-Static System — Less Mess, Better Workflow

Static is the enemy of single-dose grinding: grounds cling to the exit chute, spray across the counter, and make accurate dosing frustrating. Ascaso’s built-in anti-static system reduces the charge generated during grinding, keeping grounds together and landing in the portafilter where they belong. It’s not the flashiest feature on the spec sheet, but it’s one you’ll notice every morning.
