{"product_id":"mahlkonig-e64-ws","title":"Mahlkönig E64 WS – Espresso Grinder (Grind-by-Weight)","description":"\u003cdiv class=\"ccc-mobile-wrapper\"\u003e\n\u003ch2\u003eMahlkönig E64 WS – Home Espresso Grinder with Grind-by-Weight and Grind-by-Sync\u003c\/h2\u003e\n\u003cp\u003eAs you hook the portafilter into the fork, the grinder recognizes the weight and the display shows 0.0 g. The motor starts automatically, the 64mm special-steel burrs go to work, and the grounds fall into the portafilter. 12.0, 15.0, 17.8, 17.9, 18.0 grams – the grinder stops. Not after six seconds, not on an estimate, but at the weight you programmed. Tomorrow, the day after, in three months: the same 18.0 grams. The beans age, humidity shifts, the hopper empties – the dose stays constant.\u003c\/p\u003e\n\u003cp\u003eThe Mahlkönig E64 WS is Mahlkönig's first home espresso grinder with Grind-by-Weight and the new Grind-by-Sync technology. Introduced at HostMilano 2025, it's built on the same 64mm grinding mechanism as the professional Mahlkönig SD64, bringing a feature to the home kitchen that used to be reserved for the trade: dosing accurate to 0.1 gram, reproducible on every shot. Coffee Coaching Club is a partner of Mahlkönig in Switzerland.\u003c\/p\u003e\n\u003ch3\u003eGrind-by-Weight\u003c\/h3\u003e\n\u003cp\u003eMost electric espresso grinders grind by time. Set five seconds, and the grinder grinds for five seconds. The amount of grounds that results depends on many variables: how dense the bean is, how humid it is, how full the hopper is, how fresh the roast is. In practice, that means an 18-gram target turns into 17.4 grams one time and 18.7 grams the next. If you extract by weight ratio (1:2 as a starting point), that gives you a different extraction dynamic every time – even when the output looks right.\u003c\/p\u003e\n\u003cp\u003eThe E64 WS solves this with a built-in scale right under the portafilter fork. The grounds are weighed in real time as they fall from the burrs. The motor stops as soon as the programmed weight is reached – with a resolution of 0.1 gram. Shot-to-shot deviation stays in the tenth-of-a-gram range – more precise than most manual weighings with an external scale.\u003c\/p\u003e\n\u003cp\u003eWhat that means for taste: understanding your extraction requires a stable variable. Dose is the most fundamental one. Once it's constant, grind-size changes, bean swaps and temperature variations actually become visible in a clean way. Without a constant dose, every change is a guessing game. That's the real value of Grind-by-Weight at home.\u003c\/p\u003e\n\u003ch3\u003eGrind-by-Sync – when grinder and machine talk to each other\u003c\/h3\u003e\n\u003cp\u003eGrind-by-Sync is an interface that connects the E64 WS to compatible Mahlkönig devices. Specifically: the Mahlkönig Sync Scale or the Mahlkönig Xenia. In a Sync setup, the Sync Scale measures actual extraction time or output weight. If the shot falls outside your recipe parameters, the system reports back to the grinder: finer or coarser, automatically, to bring the next shot closer to the recipe.\u003c\/p\u003e\n\u003cp\u003eImportant context: Grind-by-Sync is an ecosystem feature. With non-Mahlkönig machines, the E64 WS works as an excellent Grind-by-Weight grinder, but without automatic grind-size adjustment. Anyone using the Sync Scale gets full automation. For everyone else, GbW remains the core feature. Functions can be extended over time through over-the-air software updates.\u003c\/p\u003e\n\u003ch3\u003eElectronic grind-size adjustment in micron steps\u003c\/h3\u003e\n\u003cp\u003eThe E64 WS has no ring, no dial for grind size. Burr distance is set electronically via a sensor-controlled motor (Disc Distance Detection, DDD) and shown on the display in microns. A single micron corresponds to roughly a one-second difference in extraction time – a precision that has been rare at this price point until now. Zero-point calibration is tool-free and guided on the display: you move the burrs together until they touch, set the zero point, done. After a burr change, the grinder is back at its reference point within minutes.\u003c\/p\u003e\n\u003cp\u003eThis includes a ball-joint spout that flexibly adapts to different portafilters, and a metal clump buster (now included as standard). The LED display has adjustable ambient lighting at the spout – the colour can be matched to your setup, if you like.\u003c\/p\u003e\n\u003ch3\u003eAt a glance\u003c\/h3\u003e\n\u003ctable class=\"ccc-compare-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrinding type\u003c\/td\u003e\n\u003ctd\u003e64mm special-steel flat burrs (same grinding chamber as Mahlkönig SD64)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBurr compatibility\u003c\/td\u003e\n\u003ctd\u003eSSP 64 mm burr sets fit (approx. 0.1 mm thicker than original – recalibrate the zero point after a change; according to Mahlkönig, fitting non-original burrs may affect the manufacturer's warranty)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDosing system\u003c\/td\u003e\n\u003ctd\u003eGrind-by-Weight (built-in scale, 0.1 g resolution)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSync function\u003c\/td\u003e\n\u003ctd\u003eGrind-by-Sync (with Mahlkönig Sync Scale or Xenia)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrind-size adjustment\u003c\/td\u003e\n\u003ctd\u003eElectronic, in micron steps, Disc Distance Detection (DDD)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor speed\u003c\/td\u003e\n\u003ctd\u003e~1950 RPM (idle, not variable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrinding rate\u003c\/td\u003e\n\u003ctd\u003e2 to 3.5 g\/s (depending on grind size)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax. daily output\u003c\/td\u003e\n\u003ctd\u003e2.5 kg (home use, not for continuous café operation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHopper capacity\u003c\/td\u003e\n\u003ctd\u003e250 g (single-dose possible with bellows)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnectivity\u003c\/td\u003e\n\u003ctd\u003eMahlkönig Sync App (iOS\/Android), over-the-air firmware updates\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003eLED, adjustable ambient lighting at the spout\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutlet\u003c\/td\u003e\n\u003ctd\u003eBall joint, adjustable for different portafilters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNoise level\u003c\/td\u003e\n\u003ctd\u003ebelow 65 dB (lab value)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWhat's included\u003c\/td\u003e\n\u003ctd\u003eE64 WS, 250 g hopper, bellows, metal clump buster, anti-popcorn lid, manual\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions with hopper (W × H × D)\u003c\/td\u003e\n\u003ctd\u003e15.4 × 39 × 21.8 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (net)\u003c\/td\u003e\n\u003ctd\u003e5.8 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage \/ power\u003c\/td\u003e\n\u003ctd\u003e220–240 V \/ 200 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection rating\u003c\/td\u003e\n\u003ctd\u003eIPX1, protection class I\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColours\u003c\/td\u003e\n\u003ctd\u003eMatte black, matte white\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturing\u003c\/td\u003e\n\u003ctd\u003eDesign by Mahlkönig (Hamburg), manufactured in China\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWho the E64 WS is for\u003c\/h3\u003e\n\u003cp\u003eThe E64 WS suits home baristas who want an electronically controlled grinder with reproducible dosing and who value convenience over tinkering. If you pull one to four shots a day with the same bean, save your recipes, and don't want to bother with an external scale every time, this delivers exactly that. Adding the Mahlkönig Sync Scale gives you the full Sync ecosystem.\u003c\/p\u003e\n\u003cp\u003eThe E64 WS isn't for everyone. If you switch between several beans daily and work consistently single-dose, you'll find in the \u003ca href=\"\/en\/collections\/varia\"\u003eVaria VS6\u003c\/a\u003e (exclusive Swiss importer) or the \u003ca href=\"\/en\/collections\/weber-workshops\"\u003eWeber Workshops EG-1\u003c\/a\u003e an alternative optimised for single-dose.

The E64 WS is a hopper-first grinder – retention in hopper mode is around 4 grams, which needs to be purged when you change beans. Its strength lies in automating dosing, not in variability.\u003c\/p\u003e\n\u003cp\u003eImportant to know: the E64 WS is designed as a home grinder. It's built for one to two espressos back to back, not for continuous commercial use. Daily output maxes out at 2.5 kg, and commercial use isn't covered by the warranty.\u003c\/p\u003e\n\u003ch3\u003eOrder directly online\u003c\/h3\u003e\n\u003cp\u003eThe Mahlkönig E64 WS can be ordered directly in our webshop.
