The Ascaso H64 is a 64 mm flat-burr home grinder with stepless micrometric adjustment, three programmable timed doses, and continuous/manual operation. The U.S. 60Hz version runs at 1650 RPM from a 245W motor, while the included hopper and single-dose accessories let the user choose between repeat hopper dosing and weighed-bean workflows.

Product Features

Stepless Micrometric Adjustment

The stepless micrometric grind adjustment gives infinite dial-in between settings so you can find the exact burr gap your espresso needs. That fine-grained control matters when small changes—fractions of a millimeter—shift extraction.

64mm Flat Steel Burrs

Built with 64mm flat steel burrs, the H64 produces a uniform particle distribution for clean, consistent extraction from espresso through cold brew. It uses the same flat burr geometry found in café grinders to reduce variability that can muddy flavor.

Quiet 245W Motor

The 245W motor runs at 1650 RPM on the 60Hz U.S. model (1350 RPM at 50Hz) and is rated around 60 dB. That combination supports a capable home workflow without the noise profile of many larger commercial grinders.

Three Timed Doses + Manual

The digital interface stores three timed doses and also provides continuous/manual grinding. It gives hopper users repeatable one-touch dosing while retaining manual control for weighing or recipe changes.

Single-Dose Mode & Blow-Out Hopper

Single-dose mode lets you grind only what you need for pour-over or AeroPress, minimizing retention; the included blow-out hopper helps purge grounds between bean changes. When you want capacity, the 300g bean hopper is ready for regular home use.

Adjustable Portafilter Holder

The adjustable portafilter holder accommodates a range of portafilter basket sizes for hands-free grinding directly into your basket. The H64 also includes a dosing cup and cup fork so you can start dialing in right away.

Our honest read

The Coffeeionado Take

Straight answers, before you buy.

Who's It For

  • Home espresso drinkers upgrading from smaller entry-level burr sets.
  • Multi-method households that want espresso and filter capability in one grinder.
  • Users who want both programmable timed dosing and a manual or single-dose option.

It's Right For You If

  • You want 64 mm flat burrs and stepless adjustment for a serious home espresso setup.
  • You want three timed dose programs but also value continuous/manual grinding.
  • You want one grinder that can cover espresso and coarser brew methods without moving into a commercial-duty machine.

Things to Consider

  • Ascaso rates the H64 for home use, so its capacity estimates assume intermittent rather than continuous café service.
  • Timed dosing is not grind-by-weight; changing beans or grind size may require retiming the dose.
  • The bellows help clear the path for single dosing, but retention varies with coffee, grind setting, and technique.

Our Take

The H64 is a well-equipped home grinder for someone who wants 64 mm flat burrs, fine stepless control, and the choice between timed hopper dosing and single-dose accessories. Its three timed programs are a useful distinction from manual-only grinders in this size class.

Full Product Description

Click to expand

Most grinders in the $500–$800 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.

1 Year Warranty ($199+ Value)

Every Ascaso H64 sold through Coffeeionado includes a 1-year warranty covering manufacturer's defects — parts included from the date of purchase. A quality grinder is a meaningful investment. If a covered manufacturer's defect occurs, our team will help coordinate the warranty process. We stand behind every machine we sell.

Paid Shipping ($59+ Value)

This coffee grinder ships free to the continental USA — handling and insurance all covered. We coordinate delivery so it arrives safely and on schedule, no hidden charges at checkout. For Caribbean and international orders, contact us for a custom quote.

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 $400 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

  • 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 — get in touch.

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.

What We'd Tell You In Person

How to Choose a Commercial Espresso Machine

How to choose a commercial espresso machine based on real volume numbers, peak hour output, and drink mix — not vague categories.

How to Choose a Commercial Grinder

Your espresso machine gets all the attention. The grinder does all the work. Every variable that determines shot quality — particle size, extraction evenness, dose consistency — starts at the grinder.

How to Design Your Cafe: Build Your Bar for the Rush

Design your café bar for peak volume, not average traffic. Equipment layout, station design, staffing ratios, and tools that remove steps — what actually matters during the rush.

Setting Up Your Commercial Espresso Machine Right

Water pressure, electrical specs, drain slope, filter flushing — what actually goes into a commercial espresso machine setup, and what gets skipped.

Product FAQ

Is the Ascaso H64 a single-dose grinder, and what is the expected retention?

The H64 supports both hopper-fed and single-dose workflows. It includes a 300 g hopper plus a small ejection hopper and bellows; the bellows help clear the grind path, but retention varies with coffee, setting, and technique.

Does the H64 use stepless adjustment for dialing in espresso?

Yes, the H64 features a micrometric stepless adjustment system. This allows for infinite control over the grind size, enabling you to make the tiny adjustments necessary to perfect your espresso extraction.

What type of burrs come standard with the H64 and can they be upgraded?

The H64 uses 64 mm flat steel burrs. The standard burr specification does not establish a DLC coating or universal compatibility with every aftermarket 64 mm burr set.

How noisy is the motor during the grinding process?

The H64 is designed for quiet home operation and is rated around 60 dB in Coffeeionado's product data. Its published specifications do not identify the motor as a DC motor.

Does this grinder have a 'Grind-by-Weight' function?

No. The H64 does not include an integrated scale. It can run from the 300 g hopper with three timed doses, or it can be used with weighed beans and the included single-dose accessories.

Is the H64 capable of grinding for filter coffee and pour-over as well as espresso?

While the H64 is primarily optimized for the precision required for espresso, its stepless range is wide enough to accommodate coarser settings for AeroPress, pour-over, and drip coffee.

Does the grinder include anti-static features to prevent mess?

The H64 is designed with an anti-static finish and comes with a dosing cup that fits snugly under the chute. While it is very clean, many users still recommend a light RDT (spritzing beans with water) for the best results in dry climates.

What is the height of the machine, and will it fit under standard US kitchen cabinets?

The grinder body is approximately 13.8 inches / 350 mm tall. Allow additional practical clearance for loading beans and operating the selected hopper or bellows.

No, we don't ship to PO boxes. Due to the size and weight of our equipment, we require delivery to a physical address where our carriers can safely drop off your order.

How does free installation work?

We want to make your purchase as smooth as possible and will pay the installation via rebate on commercial espresso machines. This includes commercial machines with more than 1 group head and 220V.

If the certified installer needed is over 1.5 hours away then we will pay for the installation call (and install up to the value suggested on page minus call fee). Travel will be paid by customer. Inquire if you have any questions about your location.


Please note, any discounts subject to void the paid installation offer.

At Coffeeionado, professional installation is included with qualifying espresso machine purchases. Our goal is to make the process as seamless as possible — from coordinating the technician to getting your machine up and running on day one.

Which Machines Qualify

Free professional installation is included with all espresso machines of 2 groups or more where indicated on the product listing. This policy applies to espresso machines only and does not cover other coffee equipment such as grinders, brewers, or accessories.

If you are unsure whether your machine qualifies, contact us before purchasing and we'll confirm.

What's Included

  • Travel and labor costs for installation within the technician's service area (up to 2 hours of travel)
  • Setup, basic programming, and commissioning of the equipment
  • Scheduling during regular business hours, Monday through Friday
  • Associated taxes and fees related to the installation itself

Installation must be completed within 90 days of delivery of the equipment. The installation benefit lapses after this window and cannot be reinstated.

How Installation Is Arranged

Depending on your purchase, installation is handled one of two ways:

Arranged directly — In many cases, Coffeeionado or the manufacturer will coordinate and pay the technician on your behalf. We will contact you after your order is processed to schedule the visit.

Reimbursement — In some cases, you may be asked to arrange the installation locally using an authorized technician and submit a rebate form for reimbursement. Once approved, the covered amount will be refunded to the original payment method used for your order.

We will confirm which arrangement applies to your purchase at the time of order confirmation. If you have questions before purchasing, contact us and we'll walk you through it.

What's Not Included

The following are outside the scope of the installation policy and remain the customer's responsibility:

  • Travel or callout costs beyond the first 2 hours of the technician's travel time — if your location falls outside the local service area, the overage is the customer's responsibility
  • Water filtration systems and installation materials — including plumbing fittings, tubing, plugs, outlets, and any other ancillary components required to prepare the site
  • Electrical or plumbing work — site preparation must be completed before the technician arrives
  • Training on equipment operation — installation covers commissioning only, not barista or operational training
  • False start or callout fees if the technician arrives and the site is not ready for installation

Important: If a technician arrives and cannot complete the installation because the site is unprepared, you will be responsible for any callout or false start fee charged by the technician. However, your installation benefit remains intact — the visit will be rescheduled at no additional cost to your policy.

Water Filtration Requirement

Water filtration must be installed and operational before or at the time of installation. This is not optional — operating a commercial espresso machine without proper filtration will void the manufacturer's warranty. If filtration is not in place at the time of the technician's visit, installation may need to be rescheduled and the callout fee will be the customer's responsibility.

If you need guidance on water filtration requirements for your machine, contact us before scheduling your installation.

Service Area

Installation coverage is tied to the manufacturer's authorized technician service area, generally within a 1.5-hour radius of the nearest certified technician. If the customer's location falls outside this area, Coffeeionado will make reasonable efforts to arrange a local authorized technician, but travel costs beyond the 2-hour coverage limit remain the customer's responsibility.

Not sure if you're in a service area? Contact us before purchasing and we'll check your location.

What to Expect on Install Day

Getting a commercial espresso machine delivered is one thing. Getting it actually running — plumbed, programmed, and pulling properly — is another. Here's what happens when the technician comes out.

Before the appointment: Site preparation will be confirmed before technicians make it out. Once your machine ships, we'll coordinate scheduling with you and assign a local certified technician. Before they arrive, make sure your space is ready: the machine's permanent location should be determined, your water line and drain access should be in place, and your electrical supply should match the machine's requirements. 

On the day The technician will handle the physical installation of the machine — positioning, water line connection, and drain setup. Once it's plumbed and powered, they'll run through the setup and basic programming: boiler pressure, shot parameters, and confirming that water flows correctly through the group heads and steam wands. Some basic training will be provided, they'll pull test shots to verify the machine is operating within spec.

After Installation

Once your machine is installed, we'll provide referrals for authorized service technicians in your area for ongoing maintenance and repairs. Coffeeionado offers lifetime support on all equipment we sell — we're here long after the install is done.

Governing Terms

This installation policy forms part of your agreement with Coffeeionado and is subject to our Terms of Sale and Terms of Service. In the event of any conflict, the Terms of Service governs.

Can I pick up the machine at your store?

We do not have a showroom or storefront for customer pickups, so orders cannot be picked up directly from us. That said, there is an exception for La Spaziale and La Pavoni products, you can contact us to arrange.

However, if you'd prefer, we can arrange to have your machine shipped to a local freight terminal/location for pickup instead. Let us know your city/state (or ZIP code), and we’d be happy to check the nearest terminal options for you.
