When it comes to making great coffee at home, choosing a grinder is nearly as crucial as selecting a prosumer espresso maker. This is not where you want to scrimp and save money. You want a grinder that can deliver fluffy, uniform, and clump-free ground coffee, and here are 9 that fit the bill.

1. Eureka Atom 75 – Best Overall

Specifications

  • Dimensions (HxWxD): 17” x 8” x 9”

  • Burrs: 75 mm flat steel
  • Grinding adjustment: Infinitesimal worm gear
  • Output: 4.5 – 5.5 g/s
  • Hopper capacity: 300 g

Eureka Atom is a fantastic grinder for the homebrewer. Though it’s not exactly cheap, it combines impressive performance with great value for money.

This is a list of the best prosumer grinders, and the Eureka Atom 75 really does the job of bridging the gap between home machines and commercial ones. The number in the name refers to the 75mm flat hardened steel burrs, with the large surface area allowing it to grind more rapidly. It’s one of the quickest on our list, with the ability to churn out espresso grind at 4.5g/s.

The Atom uses a digital timer for dosing and includes a hands-free portafilter holder. I particularly like the little LED light illuminating the portafilter as your grind — great for early mornings. Speaking of, the Atom is another super quiet grinder thanks to Eureka’s anti-vibration technology, which reduces grinding noise by about 20 dB.

This grinder features Eureka’s proprietary Anti-Clumping and Electrostaticity (ACE) system, which guarantees consistent fluffy grinds and a clean workspace. It’s an espresso-focused grinder, but the adjustment knob is one of the easiest to use, making it a painless switch to filter.

2. Rocket Faustino – Best Value for Money

Specifications

  • Dimensions (HxWxD): 15″ x 5.25″ x 9″

  • Burrs: 50 mm flat steel
  • Grinding adjustment: Infintessimal worm gear
  • Output: 1.8 g/s
  • Hopper capacity: 320 g

When looking for great value for money, it’s often worth considering the lower end grinders of a good quality brand. This is the case for the Rocket Faustino, the little brother of the well-loved Rocket Fausto. It might not have all of the features of the Italian brand’s more expensive machine, but they do have the same build quality and some of the same technology.

Inside the heavy-duty aluminium casing, you’ll find 50mm flat steel burrs. This is an average size for a home grinder, but you’ll find it won’t deliver quite the consistency of some of the larger burrs on this list, especially on the coarser end of the scale. It does have the advantage of a worm gear knob, which allows for stepless, infinitesimal adjustment rather than limiting you to preset options.

Dosing is done by way of the top-mounted touch screen, with the options of single shot, double shot or continuous grinding. The doses by shot are programmable, based on grind time. Other user-friendly features include a portafilter holder for hands-free grinding and anti-vibration technology that the brand claims to reduce noise by 20dB.

The Faustino is more compact than its big brother, making it a better pick from small kitchens. The downside to this is that to get a smaller machine, Rocket have cut the hopper capacity significantly. Holding just 320g of beans, you’re going to be refilling more often.

3. Baratza Sette 270wi – Most Versatile

Specifications

  • Dimensions (HxWxD): 15.8” x 5.1” x 9.5”

  • Burrs: 40 mm conical steel
  • Grinding adjustment: Stepped collar adjustment
  • Output: 3.5 g/s
  • Hopper capacity: 275 g 

The Baratza Sette 270Wi is an upgrade to the 270 model, which is one of our favourite entry-level grinders. This model maintains all of the original’s features, but with one significant change: you can grind by weight directly into the portafilter. This is much more accurate than dosing by time and, of course, comes with a bump in price compared to the original.

Baratza is one of few grinder manufacturers focused on domestic rather than commercial use (1). As such, the Sette 270Wi is nice and compact. With a 40 mm set of conical burrs, 30 macro settings, and 9 micro-adjustments, it’s designed to grind for any standard brew method. That said, most users find it performs best at a finer grind.

Uniquely, the Baratza Sette has inverted burrs. The top one rotates rather than the bottom. This allows it to grind faster, produce fluffier grounds and means you get virtually zero retention. The retention on this grinder is far less than many double its price.

The main downside to the Sette is its volume. For such a small machine, it can make a real racket. In the past, it had durability issues, now mostly resolved, and a solid warranty backs it. Keeping in mind that it’s an affordable plastic grinder that isn’t built to last decades.

If conical burrs aren’t your thing, the Baratza Vario is a very similar burr coffee grinder with 54 mm flat burrs.

4. Victoria Arduino Mythos One – Best High End

Specifications

  • Dimensions (HxWxD): 20″ x 8″ x 16″

  • Burrs: 75 mm flat titanium-coated steel
  • Grinding adjustment: Stepless micrometric
  • Output: 2.7 g/s
  • Hopper capacity: 1.3 kg

If you’ve got some cash to splash, and an espresso machine to match, you might want to consider something at the “pro” end of the prosumer range. Enter the Victoria Arduino Mythos One, which would look just as at home in a coffee shop as it would next to the Slayer in your kitchen.

The Mythos One represents two years of development to solve some of the most common issues facing baristas. The result is a new generation of grinders with two brand technological features: the Clima Pro and Clump Crusher systems.

The Clima Pro ensures the mill maintains a consistent temperature, not just from start to finish, but across a whole day of grinding, and in any climate. Even if you’re not running a cafe, this feature will ensure you get the best taste out of your beans. The Clump Crusher minimises waste and reduces the need to purge between grinds, by way of an anti-clump screen and chute. It also makes for a fluffier grind.

It’s not a small piece of tech, with a 1.3 kg capacity hopper designed for cafe use. But it is slim, so you can tuck it away neatly next to your espresso maker. Doses are programmed through three buttons on the front. It’s an incredibly efficient system that allows you to adjust on the fly down to hundredths of a second. Grind size is adjusted by an easy-to-use knob, with infinite, stepless adjustments.

Burrs are a hefty 75mm, which you’d expect from a grinder at this price point, and are made from titanium-coated steel for added precision and durability. You’re going to get through a lot of grinding before these need replacing.

5. Mazzer Mini – Best for Small Spaces

Specifications

  • Dimensions (HxWxD): 16.5” x 6.8” x 13.2”

  • Burrs: 58 mm flat steel
  • Grinding adjustment: Infinitesimal collar adjustment
  • Output: 1.5 g/s
  • Hopper capacity: 600 g

Prosumer grinders, by their nature, are not small. Most were built for the commercial environment but found their way into homes when prosumer-grade espresso machines took off (2).

If you really don’t have space, consider a top-of-the-line hand grinder. But if you have a little room to manoeuvre, the Mazzer Mini is one of the most compact options.

Its footprint is 6.8″ x 13.2,” and it’s well under the standard 18″ cupboard clearance. Even with the large 600 g bean hopper! Sure, it weighs a hefty 22 pounds, but that’s a good sign of a sturdy build. It has a pretty sleek look, despite the doser parked on the front. Best of all, it comes in an array of colours to coordinate with the rest of your coffee bar.

It grinds with a pair of 58 mm flat steel burrs and uses a step-less adjustment, so you can perfectly dial in your espresso. It’s capable of filter grind, but it’s not the most versatile coffee grinder out there. I’d suggest this one for primarily espresso drinkers.

The most notable feature of the Mini is the doser, which speaks to its past commercial use. You can set it to dose between 5.5 g and 9 g with each pull of the lever. The main advantages of a doser for home users are less mess and better consistency. The Mazzer Mini is also available in a doserless version, and you can read more about the difference in the Buyer’s Guide.

If you’re looking for a compact grinder and prefer the single dosing workflow, the Niche Zero is another great option.

6. Eureka Mignon Specialita – Best for Quiet Grinding

Specifications

  • Dimensions (HxWxD): 13.78” x 4.72” x 7.1”

  • Burrs: 55 mm flat steel
  • Grinding adjustment: Infinitesimal worm gear
  • Output: 1.5 – 2.5 g/s
  • Hopper capacity: 300 g

Eureka’s Mignon series of grinders is a common entry point for the prosumer grinder market. They’re reasonably priced, quiet, have great burr sets, and are easy to use. Each model in the line-up has its selling point, but I’m partial to the Specialita.

It’s a bit higher-end than some others, with a larger 55 mm burr set for fast grinding. It also has remarkably low retention, so it’s suitable for single dosing. The touchscreen display is effortless to use, even before you’ve had your first coffee of the day.

The entire Mignon series shares a similar aesthetic, with a boxy modern design. For example, the Specialita is available in various colours, including exotic things like pink-gold and lime green. Mignon grinders are the quietest on the market because Eureka uses a sound-insulated thick metal casing and dampening rubber.

If quiet is really a priority, you might prefer the Mignon Silenzio, which has a lesser burr set but was designed with silence in mind. Silenzio is the Italian word for silence.

The Specialita uses the same patented step-less micrometric adjustment as the more expensive Atom, so it’s easy to transition from espresso to filter. And like the Atom, you can take it apart for cleaning without having to recalibrate.

7. Fellow Ode – Best for Single Dosing

Specifications

  • Dimensions (HxWxD): 9.4″ x 4.2″ x 9.5″

  • Burrs: 64 mm flat steel
  • Grinding adjustment: 31 stepped settings
  • Output: not specified
  • Hopper capacity: 80 g

Many new products get their start on crowdfunding sites, but there aren’t many that go on to succeed in the long run. To be fair, Fellow was already an established coffee gear brand when they put the Ode up on Kickstarter, but the reaction it received was undeniable: $200,000 in 94 minutes. Two years later and not only is the Ode still selling, it’s also taken out a Specialty Coffee Association (SCA) award for Best New Product in 2021 (3)

So why all the hype? Well, the minimalist black design makes it stand out from the crowd, but it’s what’s inside that counts. First are the 64mm flat burrs, a larger size than what’s normally seen in home grinders. Then there’s the PID motor that gives a more consistent grind, while reducing both heat and noise. Finally, there’s a grinds knocker to ensure none of your ground coffee stays in the chute. Again, it’s a feature normally only seen on commercial machines, but we’d say it’s almost essential on a single dose grinder.

Before you go getting out your credit card, there’s one thing you need to know: the Ode doesn’t grind for espresso. This was a conscious decision by the designers, not a shortcoming of the machinery. They decided to focus on doing one thing well rather than try to cater to everyone, especially at this price point. But if you’re looking for a grinder for pour over, French press or cold brew, the Ode has got you covered.

8. Rancilio Rocky – Budget Pick

Specifications

  • Dimensions (HxWxD): 13.8″ x 4.7″ x 9.8″

  • Burrs: 50 mm flat steel
  • Grinding adjustment: 55 stepped settings
  • Output: 0.69-0.97 g/s
  • Hopper capacity: 300 g

The Italian Rancilio brand is known for its range of quality espresso machines. So when it comes to producing a grinder, you know that they’ve got the end use in mind. 

The Rocky is designed for home use, but it shares the same quality of burrs as the Rancilio professional line. It does of course miss out on some of the user-friendly features of more expensive machines. There’s no programmable dosing here, just a pulse button beneath the hopper.

You can adjust the grind size by twisting the bean hopper, with 55 stepped options. This is where the Rocky holds its own, with the ability to produce both super fine grounds at one end and an extra coarse grind at the other. If you have the doserless version you can grind straight into the portafilter, or remove the portafilter holder to grind for French press or pour over.

The budget cost is more obvious when it comes to the output. Grinding less than 1g of espresso per second, you’re going to be waiting longer for your coffee. But if you’re eyeing off a grinder at this price point, we’re assuming you’re not running a busy cafe.

9. Fiorenzato F4E V2 – Great Value

Specifications

  • Dimensions (HxWxD): 17” x 6.7” x 9.4”

  • Burrs: 58 mm flat steel
  • Grinding adjustment: Infinitesimal collar adjustment
  • Output: 1.5 g/s
  • Hopper capacity: 500 g

I love the Fiorenzato F4E V2 for a great value pick, which nicely balances price with function. It’s not the cheapest grinder on the list, but it delivers beyond what its price would suggest.

The 58 mm flat steel burrs deliver uniform, fluffy grounds, and the micrometric collar adjustment gives you the kind of control typically found on far more expensive grinders. It has the low retention of a more expensive grinder and gives it the versatility for single dosing.

Though it has a wide range of grind settings, it’s best if you used it as a dedicated espresso grinder. The step-less adjustment is quite stiff, requiring some muscle to move, and it doesn’t have an arrow to mark your place.

It has a friendly style, sleek lines, multiple colour options, and a narrow frame that suits domestic use. It’s topped with a 500 g hopper but will still fit under standard cupboards, and the large stainless steel catch tray keeps any mess under control. The aluminium body has been designed for noise dampening, so it’s one of the quieter coffee grinders for the price.

You operate the latest version of the Fiorenzato F4E with a light-up colour touchscreen, where you can choose a single shot, double shot, or manual timing. The portafilter locks in for a hands-free operation.

You’ll find the Rocket Faustino flat burr coffee grinder around the same price point, which looks great next to Rocket espresso machines. But I’d venture that the much bigger burr set in the F4E makes it a better value.

How to Choose the Best Prosumer Coffee Grinder

You might be surprised to learn that choosing a grinder can be just as complicated as selecting an espresso machine. Many factors can influence the grind quality, workflow efficiency, and price. This detailed buyers guide is here to walk you through all of them.

It’s All About The Burrs.

The burrs are the heart of your coffee grinder. Their size, shape, and material largely dictate the quality of your ground coffee.

Burr Shape

There are two main burr shapes, flat and conical, and the debate rages as to which is better. Flat burrs sit atop one another horizontally, and the distance between them determines grind size. Conical burrs grind vertically, with one sitting inside the other (4).

The geometry of flat burrs makes them easier to align correctly, which leads to greater consistency. But the trade-off is that they can heat up more with heavy use, though home users have little to fear.
Conical burr grinders usually offer lower grind retention, and they can grind at lower rpm because gravity is working in their favour. That means quieter operation and less popcorning. Like David Schomer of Seattle’s Espresso Vivace, some experts also prefer a conical burr set for a richer shot of espresso (5).

I favour conical burrs because they produce micro-particles that add flavour and body to the shot compared to flat burrs.

Some coffee connoisseurs insist that there is a taste difference between the burr shapes. A conical burr grinder set is better for brighter coffees, whereas flat burrs enhance darker chocolate notes. But there is little evidence to support this.

Burr Material

The main impact of the burr material is on durability and longevity. Most grinders have hardened steel burrs at the prosumer level, whereas lower-end burr coffee grinders favour ceramic.

At the more expensive end, you’ll find titanium burrs or titanium nitride-coated burrs. These materials don’t affect grind quality, but they should last much longer.

Burr Size

Finally, let’s talk size. Though it’s easy to be persuaded that bigger is always better. This is not necessarily true. Bigger burrs grind faster, which is useful in a commercial environment. But in a home setting, the alignment of the burrs has a much greater impact on quality than the size.

What Do You Like to Brew?

When we talk about prosumer coffee grinders, we’re talking about something suitable for use with prosumer espresso machines. But if you often enjoy filter coffee, you should either look for a grinder versatile enough for any brew method or budget for two grinders.

Most coffee grinders at the prosumer level can achieve filter or espresso grind, but some are difficult to switch between the two settings.

Single Dosing or a Bean Hopper

With a single dosing grinder, you weigh out exactly the beans you need for your brew, add them to the grinder, and grind until they’re done. The advantages are obvious, especially if you don’t drink a ton of coffee.

Dosing by weight is more accurate than dosing by time. You don’t have beans going stale, and the design is more compact without a hopper.

They’re also great if you regularly change coffees, and they tend to be low retention.

But a hopper has pros too.

The beans’ weight in the hopper provides a steady pressure feeding the beans into the burrs, eliminating popcorning and producing a move-even grind (6). And not having to weigh out your beans saves time in your morning routine.

Does Grind Retention Matter?

Grind retention refers to two possible issues within the grinder. Either the weight of beans you put in doesn’t match the weight of grounds you get out. Or the weight matches, but some of what comes out is stale grounds trapped during the last use. Neither is ideal for brewing consistent coffee, so the best coffee grinders for home use tend to be low retention.

Stepped or Step-less Grind Adjustment?

Most prosumer espresso grinders offer step-less adjustment because you need a sufficient level of control to dial in espresso. That is not to say that a stepped model can’t make good espresso, but you run the risk of that perfect extraction being trapped between two settings. If you only make espresso, especially if you often switch coffees, a step-less adjustment is a way to go.

On the other hand, if you regularly switch from filter to espresso, a stepped grinder will make it easier to return to your place.

Do I Need a Doser?

Dosing grinders are more common in commercial settings than the home, but there are a few reasons you might want one. They work by grinding the coffee into a dosing chamber, and then a lever is pulled to dose a specific amount into the portafilter. This is a quick, practical, and mess-free option that eliminates some concerns about grind retention.

However, since the doser only operates when it’s full, you run the risk of grinding more than you need and letting some go stale. Dosing grinders are also less flexible, as they’re primarily used for espresso.

Lately, with improvements in grind retention, home users more often opt for single dosing grinders rather than dosers.

The Verdict

Just like your choice of the espresso machine, your choice of grinder will have a big effect on your coffee.

For an excellent all-around grinder, I love the Ceado E37S. It’s fast, quiet, versatile, and easy to use. If you don’t have the budget for the Ceado, the runner-up Eureka Atom 75 is nearly as impressive at two-thirds the cost.

FAQs

Steel burrs don’t heat up more than ceramic burrs during grinding. This is a common myth. The truth is that steel burrs have higher thermal conductivity, but this transfers heat away from the coffee beans (7).

A faster motor grinds coffee more quickly, so the beans don’t have as much time to heat up — not to mention you’ll get your coffee faster. However, higher rpm also leads to more popcorning and likely a louder grinder.

Yes, you can use a hand grinder with a prosumer espresso machine. Indeed, something like the manual 1Zpresso JX Pro is a far better budget choice than opting for an electric blade grinder. Just remember that the finer the grind, the more work it will be. So if you drink a lot of good espressos, you’ll need strong arms!
