Thank you this is really helpful. I have not had a similar experience and gbw on my grinder has always been roughly above 0.3-0.5g, even after calibrating multiple times with a 1kg weight. Reaching out to Mahlkonig currently to see what they think. It wasn’t a flag for me initially bc I thought the grinder needed to settle but I’m finding that the gbw system should be extremely precise out of box and even after calibrating.
Yes and also eureka mignon. The motor on e64ws doesn't stall, I've had the eureka stall, but the e64ws does have far better made carriers which also helps it not stall.
The e64ws is precise to 0.001mm thanks to it's servo motor, the Eureka has that small knob that graduates off either an M5 or M6 threaded rod, can't remember but either way that's either 0.8mm or 1mm pitch on not more than 6mm, making dialling in as accurately as the E64ws impossible.
The GBW aspect on the e64ws is simply better. It is smoother and more accurate.
The e64ws grounds are also fluffier if that is important.
The e64ws is basically an e65s built for home. An exceptional grinder, while the Eurekas are not built to that standard.
A few different ways. You can adjust while it spins by hold grind button and adjust or input a gap and the motor will adjust to setting. You hold the grind button while it lowers.
No, it doesn't stall. The e64ws has a very efficient motor.
If the input is too large , 100 microns for example. The grinder won't allow that large an adjustment and will ask you to grind first.
You can also set it so that it doesn't automatically adjust to a different recipes gap. I have mine set to auto and have not had any issues.
The grinder also has the option to help with your brew. Set weight and time. It will then adjust based on how long you input for time taken to get to your weight. That particular feature has been spot on. So impressive.
After awhile it's easy to get the hang of the adjustments and how they relate to extraction time. I now know for every micron I get 1 second change in extraction time with my coffees.
E64ws makes it so simple and is the easiest grinder to dial in.
It's not always adjusting though, maybe it's my specific use case.
I buy 1kg beans, put them in 200 gram ziplock bags and freeze them. I load about 100 gram of beans every 2nd day. My grind hasn't changed for the entire kg, doing that.
The only time I adjust my grind size is for a new type of coffee.
You can also not use that feature and manually adjust and spin as you usually would, if you're more comfortable with that. Again it's nothing like the Eureka motor which is very inefficient and stalled frequently on me.
| Grinder | Burrs & size | GBW style | Best use case | Notable strengths | Main drawbacks |
| --- | --- | --- | --- | --- | --- |
| Baratza Vario W+ | 54 mm flat steel burrs, home‑oriented | GBW only, into bin | Home espresso + filter | Versatile, compact, good value; designed for home duty | Lighter build than Forte; GBW not into PF by default |
| Baratza Forte AP | 54 mm flat **ceramic** flat burrs | Time or GBW, PF or bin | All‑purpose, espresso‑forward; home or low‑volume café | Commercial‑grade build, 260 stepped settings, by‑time or by‑weight, PF holder, stronger motor than Vario | Louder and pricier than Vario; still 54 mm vs 64–75 mm class |
| Eureka Mignon Libra | 55 mm flat, espresso oriented | GBW into PF | Compact home espresso GBW | Quiet, small footprint, accurate GBW into PF | Less heavy‑duty than Atom; retention only “okay” |
| Eureka Atom W65/W75 | 65/75 mm espresso burrs | GBW, hands‑free PF | Prosumer / light‑commercial espresso bar | Fast, quiet, very slick PF‑docking GBW workflow | Large, expensive; overkill for light use |
| Mahlkönig E64 WS | 64 mm GBW espresso grinder | GBW, hopper‑fed | High‑end home / prosumer espresso | Very consistent, “pro” feel, strong value in 64 mm GBW segment | Bigger and more industrial feel; louder than a Mignon |
| Fiorenzato All Ground Sense | 64 mm multi‑purpose burrs | GBW, multi‑mode | Smart, feature‑rich home grinder (espresso + brew) | Highly regarded performance, flexible modes, modern UX; often rated ahead of Eureka GBW line overall | Retention only average; price above entry GBW options |
So, the grinder is setup and grinding. Coming from a Eureka Specialita Turbo no tears yet. Look, I enjoy gatekeeping from time to time as much as the next guy. I get it, it's not a $3K Mahlkonig, it's not built as robustly as commercial machines, and the location of final assembly is different. Having gotten that out of the way, if given the choice of a $750 Libra on a flawed Mignon platform, or this for a few hundred more, you will have to begrudgingly agree that the choice is rather simple. Eureka charges > $1K for the Atom, same flawed platform, same sparse features.
You get most of what makes the big boys great, the OS, DDT, local cell, GBS, in a price that is palatable for the average home user. And to be fair, you also get the retention that comes with a flat burr hopper fed grinder. Frankly, I think the price point is right on the money. Unless you are the proud owner of a E65 and still making payments on your credit card, I really don't understand your obsession with railing against this product.
My complaints with it, for others who may be interested, are exactly the same as other posters:
1. The manual is terrible. That's because you have to scan QR codes to get into the detailed software and hardware manuals. The included books are useless.
2. The chute slides to its lowest position during the grind causing the grinds to fluff up on the upper fork. Not good. I have to jam something behind the chute as another owner did.

Hey. So, the E64 is doing great. Excellent GbW, nice aesthetics, gorgeous large screen, and tactile scroll wheel. Used the onboard app to dial in a new bean, not rocket science but it got it there quickly. Overall a really nice, relatively quiet grinder, with excellent countertop presence and aesthetics.
I am SN 130
I would try another one. The other two grinders are nice and I’ve considered the Fiorenzato, but don’t have the UI large interface GbS and trick tech.
Coming from a Eureka this is a step up, but then again so is the price tag.
Mahlkönig has a 10% code as well.
I'm also an owner, yeah the Disc Distance Tech ("DDT") is very space tech. You change a the distance and then hear a slight high-pitched buzz as the discs adjust. What's interesting, to me, is how it's able to adjust for a finer grind, with left over ground up beans inside the burr chamber. I don't hear the burrs crushing any beans as they adjust.
Hey. I just unpacked my black E64WS. Grinder is great, light years ahead of Eureka's grinding platform, but noise wise, these two are pretty comparable. The Mignon series really were quiet.
My biggest complaint is that the silver grinds chute will slip and revert to its lowest most position during the grinding process. This causes the fluffy grinds to clump up on the upper fork, and not neatly in the PF. I have to hold the chute with a finger to have the coffee clump in the PF only. My serial number is between 100 and 150. Another owner stuck something back there, and it looks like I will have to do same.
Thanks. It is a big disappointment that this is happening. I guess this is what I get for compromising on my initial quest for GBW Italian made grinder.
I wasn't aware of the Mahlkonig manufacturing being done outside of Germany for the E64 WS. But now I am. lol
After reading all of the trash talking because of the secondary manufacturing I was expecting a cheap-ish build quality. I was pleasantly surprised with it being quite the opposite.
I opted for a refund while the bugs get sorted out. I'll look to go with something different. The Mazzer Mini G and Fiorenzato F64 EVO Pro are the two that I'm leaning towards.
What is the manufacturer date of your E64 WS? Mine was 11/2025 with a unit number of 195.
I am stepping up from a Eureka too. The Eureka Oro Mignon single dose. Prior to stumbling upon the E64 WS I was leaning heavily towards the E65W GbS. Totally overkill for home use, but YOLO.
Ahhhhh funny you mention the Ceado Rev. For a hot minute that unit was top of my list. Since it wasn't available at the time I ascended deeper into the rabbit hole in search of GBW grinders.
Fortunately I have no height restrictions on my counter so my options remain wide open. Decisions. Decisions.
