Change the grind by a few microns, the beans age a day, the kitchen humidity shifts, and yesterday’s 18-gram dose is 16.8 or 19.4 this morning. You end up with a scale on the counter, a timer you no longer trust, and a shot that only lands when you stand there and watch it.\u003c\/p\u003e\n\u003cp\u003eThe Mahlkönig E64 WS is built around the idea that it shouldn’t have to be that way.\u003c\/p\u003e\n\u003cp\u003eThe Mahlkönig E64 WS Home Espresso Grinder brings Grind-by-Weight and Mahlkönig’s Disc Distance Detection, technology that used to live on café grinders, onto a home counter that is about six inches wide. Special steel 64 mm flat burrs share a grinding chamber with Mahlkönig’s SD64. A load cell under the portafilter fork stops the motor at the weight you programmed, to 0.1 g. Set the burr gap from the screen in microns, not from a collar you hope you can find again tomorrow. Hang a portafilter, pick a recipe, grind.\u003c\/p\u003e\n\u003cp\u003eWS stands for Weight \u0026amp; Sync. Pair the grinder with a compatible machine or the Mahlkönig Sync Scale, and grind size can follow the shot, not the other way around. Compact enough to live under a cabinet. Quiet enough for an early kitchen. Backed by Espresso Parts' parts inventory and support when you need a flapper, a hopper, or a human.\u003c\/p\u003e\n\u003ch2\u003eMahlkönig E64 WS Home Espresso Grinder Features That Deliver\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003e64 mm Special Steel Flat Burrs\u003c\/strong\u003e\u003cbr\u003eThe E64 WS uses 64 mm special steel flat burrs in the same grinding chamber as Mahlkönig’s SD64. At roughly 1,950 RPM idle they move 2–3.5 g per second depending on grind, so an 18 g espresso dose typically lands in about 7–8.5 seconds. The particle set is built for balanced, sweet espresso on the medium and darker roasts most home machines actually drink well: café DNA without a café footprint.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrind-by-Weight to 0.1 g\u003c\/strong\u003e\u003cbr\u003eA load cell under the portafilter fork tares the basket and stops the motor at the programmed dose. Change grind size, change beans, wait a day, and the weight still lands. Independent testing has shown dose standard deviation around 0.07 g when the fork is set up correctly. That is the difference between weighing every shot and pulling the shot.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eElectronic Micron Adjustment (Disc Distance Detection)\u003c\/strong\u003e\u003cbr\u003eThere is no grind collar. A motorized Disc Distance Detection system measures burr gap and displays it in microns. Save grind position to a recipe. Recalibrate zero from the screen, no tools. This is the same DDD idea Mahlkönig put on its pro line, scaled into a 12.8 lb home body, so you can set it and come back to it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePortafilter Recognition\u003c\/strong\u003e\u003cbr\u003eProgram up to ten portafilters. Hang one on the fork, and the grinder can load the matching dose. A ball-joint spout aims into 58 mm baskets. Customizable chute lighting is the vanity feature. Portafilter memory saves a weekday morning.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrind-by-Sync\u003c\/strong\u003e\u003cbr\u003eConnect the E64 WS to a compatible La Marzocco or Sanremo machine, a Mahlkönig Xenia, or the Mahlkönig Sync Scale. Shot data can come back to the grinder so grind size follows extraction instead of living as a guess you chase after every bag. Confirm the current compatibility list at purchase. The list grows as Mahlkönig adds partners.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHopper First, Single-Dose When You Need It\u003c\/strong\u003e\u003cbr\u003eThe native workflow is a 250 g hopper. Permanent retention in published tests is low, around 0.3 g. Exchange retention is real, around 3.8 g. Purge after idle time or when you change coffee. A bellows and anti-popcorn lid ship in the box so you can single-dose without buying a third-party kit. This hopper grinder can single-dose. It is not a purpose-built zero-exchange single-doser.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHome Footprint, Home Volume\u003c\/strong\u003e\u003cbr\u003eAbout 6\" wide, 8.6\" deep, 15.4\" tall with hopper, 12.8 lb. The motor is specified for home and residential use, not a café bar. Manufacturer lab noise is rated under 65 dB. It is still a 64 mm flat burr grinder, just a quiet one. Matte Black and Matte White. Wi-Fi, Sync app, and over-the-air updates keep the software current. Connect it.\u003c\/p\u003e\n\u003ch2\u003eWho the Mahlkönig E64 WS Is For\u003c\/h2\u003e\n\u003cp\u003eThe E64 WS is for the home barista who no longer wants a scale, a timer, and a notebook next to the machine every morning. For the espresso drinker who runs one or two house coffees, pulls one to six drinks a day, and wants the dose to be the least interesting part of the ritual. For the buyer who wants Mahlkönig micron control without stepping up to a $2,000+ E65S GbW.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIt’s the right fit for:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHome baristas with a mid- or high-end espresso machine who want weight-based dosing and digital grind control in one compact body.\u003c\/li\u003e\n\u003cli\u003eHouseholds that keep beans in the hopper and value repeatability over rotating a new bag every other day.\u003c\/li\u003e\n\u003cli\u003eBuyers who want Grind-by-Sync now or want the option when they add a compatible machine or Sync Scale.\u003c\/li\u003e\n\u003cli\u003eAnyone stepping up from a timed 50–55 mm home grinder who is tired of chasing dose after every grind tweak.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eLook elsewhere if:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eYou change coffees every shot and want near-zero retention between doses. That job belongs to the Mahlkönig X64 SD or another true single-dose grinder.\u003c\/li\u003e\n\u003cli\u003eYou need café throughput. Stay on the E65S GbW or E80. The E64 WS is specified for home duty.\u003c\/li\u003e\n\u003cli\u003eYou want one grinder to live equally at espresso and French press. The X54 is the all-purpose tool in this family. The E64 WS is espresso-first.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eMahlkönig E64 WS vs. Mahlkönig X54\u003c\/h2\u003e\n\u003cp\u003eThe X54 is Mahlkönig’s all-purpose home grinder: 54 mm Hamburg-made flats, stepless collar, timed presets, espresso through French press, $599. It is the right tool when one machine has to cover every brew method on the counter.\u003c\/p\u003e\n\u003cp\u003eThe E64 WS is a different job. Larger 64 mm flats, a built-in scale, electronic micron adjustment, portafilter recognition, and Sync. It costs more because it removes the two variables that wreck weekday espresso: dose weight and grind position you cannot see. It does not try to be the household’s pour-over grinder.\u003c\/p\u003e\n\u003cp\u003eChoose the X54 when you want one quiet all-purpose grinder and timed dosing is enough. Choose the E64 WS when espresso is the main drink and you want the dose and the grind number to hold still.\u003c\/p\u003e\n\u003ch2\u003eMahlkönig E64 WS vs. Mahlkönig X64 SD\u003c\/h2\u003e\n\u003cp\u003eThe X64 SD is built around single dosing: 64 mm flats, bellows, anti-popcorn, and an almost hopper-free workflow. It is the cleaner tool if you weigh beans, grind, and purge every drink, and you switch coffees constantly.\u003c\/p\u003e\n\u003cp\u003eThe E64 WS can single-dose with the included bellows. Its native life is the hopper plus grind-by-weight. Permanent retention is low. Exchange retention matters if you rotate beans. If freshness per bag is the religion, buy the X64 SD. If weekday speed and a programmed 18.0 g are the religion, buy the E64 WS.\u003c\/p\u003e\n\u003ch2\u003eMahlkönig E64 WS vs. Mahlkönig E65S GbW\u003c\/h2\u003e\n\u003cp\u003eThe E65S GbW is the café benchmark: bigger body, far higher throughput, higher price, same grind-by-weight philosophy. It is oversized for most kitchens and correctly sized for a bar.\u003c\/p\u003e\n\u003cp\u003eThe E64 WS puts weight-based dosing and DDD into a home footprint at roughly half the spend. Same brand idea. Different duty cycle.\u003c\/p\u003e\n\u003cp\u003eChoose the E65S GbW if you are serving a line. Choose the E64 WS if you are serving a household.\u003c\/p\u003e\n\u003ch2\u003eMahlkönig E64 WS vs. Eureka Atom W 65 \/ Libra-class grinders\u003c\/h2\u003e\n\u003cp\u003eEureka’s weight-based home grinders win on price and a simpler interface. They do not give you Mahlkönig’s micron DDD, portafilter memory, or the Sync ecosystem. If the budget is the constraint and you only need a scale in the fork, Eureka is a rational buy. If you want grind position you can read, save, and send to a machine, the E64 WS is the more complete instrument.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Takeaway\u003c\/strong\u003e\u003cbr\u003eThe X54 wins on all-purpose range and price. The X64 SD wins on single-dose freshness. The E65S GbW wins on café speed. Eureka wins on a lower ticket. The Mahlkönig E64 WS is the choice for the home barista who wants genuine grind-by-weight, micron grind control, and a path into Grind-by-Sync: café ideas, home size, espresso first.\u003c\/p\u003e\n\u003ch2\u003eWhat’s Included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eE64 WS grinder (Matte Black or Matte White)\u003c\/li\u003e\n\u003cli\u003e250 g hopper\u003c\/li\u003e\n\u003cli\u003eBellows\u003c\/li\u003e\n\u003cli\u003eMetal clump-buster \/ flapper\u003c\/li\u003e\n\u003cli\u003eAnti-popcorn lid\u003c\/li\u003e\n\u003cli\u003eUser manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eRecommended with this grinder: 58 mm dosing funnel or ring (grounds run fluffy), WDT tool, and the Mahlkönig Sync Scale if you want Grind-by-Sync without a compatible machine.\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I still need a coffee scale?\u003c\/strong\u003e\u003cbr\u003eA: Not for dosing. The built-in load cell tares the portafilter and stops at the programmed weight. Keep a scale under the cup if you track brew ratio. You need the Mahlkönig Sync Scale, or a compatible machine, only if you want Grind-by-Sync to nudge grind after the shot.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the E64 WS single-dose?\u003c\/strong\u003e\u003cbr\u003eA: Yes, with one important nuance. The included bellows and lid make single-dosing possible. The native design is still a hopper grinder with grind-by-weight. Permanent retention is low. Exchange retention is real. If you change coffee every shot, the X64 SD is the cleaner tool. If you live on one or two house beans, the E64 WS is the faster morning.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this an all-purpose grinder like the X54?\u003c\/strong\u003e\u003cbr\u003eA: No. The E64 WS is espresso-first. The X54 is the all-purpose grinder in this family. Buy the tool that matches the drink you actually make most days.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What does WS mean?\u003c\/strong\u003e\u003cbr\u003eA: Weight \u0026amp; Sync. Grind-by-weight is onboard. Grind-by-Sync is the connection to compatible machines and the Sync Scale.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does Grind-by-Sync work without a Mahlkönig Xenia?\u003c\/strong\u003e\u003cbr\u003eA: Yes. Listed La Marzocco and Sanremo models and the Sync Scale are part of the ecosystem. Compatibility changes. Check the current list before you buy a machine around this feature.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How loud is it?\u003c\/strong\u003e\u003cbr\u003eA: Mahlkönig rates laboratory noise under 65 dB. Independent peak measurements run higher, as they do on every flat-burr grinder. It is quiet for the class. It is not silent.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do the grounds need a dosing funnel?\u003c\/strong\u003e\u003cbr\u003eA: Strongly recommended. The grounds run fluffy. A 58 mm funnel or ring keeps the dose in the basket and helps the scale read cleanly. We stock them next to this grinder for a reason.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How is this different from the E65S GbW?\u003c\/strong\u003e\u003cbr\u003eA: Same philosophy, different job. The E65S GbW is a café grinder. The E64 WS is the home version of weight-based dosing and electronic grind control. If you are pulling drinks for a household, buy this. If you are serving a line, stay on E65S or E80.\u003c\/p\u003e\n\u003ch2\u003eAbout Mahlkönig\u003c\/h2\u003e\n\u003cp\u003eMahlkönig is often regarded as the King of Grinders in specialty coffee, and for good reason.
