Mahlkönig · Flat burrE65S GbW
A commercial-grade 65mm flat burr grinder with a built-in load cell for real-time grind-by-weight dosing, aimed at cafes that need speed and repeatability without babysitting a separate scale.
The short version
This is a workhorse cafe grinder that happens to weigh your dose as it grinds, not a home single-doser dressed up in commercial clothes.
Buy it for the GbW accuracy and portafilter-detection workflow, and accept that it wants a hopper of beans and daily volume to justify its size and price.
Why people buy it
- Real-time load-cell dosing hits target weight reliably, typically within a couple tenths of a gram once calibrated
- Fast grind speed (roughly 4-7 g/s) keeps queues moving during rushes
Why they don’t
- Scale drifts a few percent over a session and needs periodic recalibration for single-dose accuracy
The full tally
- Real-time load-cell dosing hits target weight reliably, typically within a couple tenths of a gram once calibrated
- Fast grind speed (roughly 4-7 g/s) keeps queues moving during rushes
- Portafilter detection auto-selects presets and starts grinding hands-free, cutting training time
- Active cooling and upgraded internals keep grind temperature stable across long, heavy-use sessions
- Scale drifts a few percent over a session and needs periodic recalibration for single-dose accuracy
- Discontinued by Mahlkönig in favor of the newer E65W GbS (Sync) line, so long-term parts support is a question mark
- Sizeable, hopper-fed commercial footprint that is overkill and pricey for most home setups
What the community knows
Years of owner threads, distilled — a niche favourite.
Commercial-class flat-burr workhorse with GbW precision and decades-long durability if calibration discipline is maintained; narrow niche because duty-cycle constraints and model discontinuation limit home use, while GbW adds $300–500 premium over base E65S with minimal…

Worth knowing before you buy — Most owners ask themselves "Do I actually grind 66 lbs/day?" before buying—heavy investment that shines only in sustained-use workflows.
Known weak points — Software glitches on startup reported in early units; thermal cutoff triggered if duty cycle exceeded; scale calibration drift if portafilter weight not zero-referenced before use.

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners moving from single-dose home grinders (Lagom P64, Eureka Atom/Olympus) upgrade to the E65S GbW mainly for speed and hands-free GbW workflow in higher-volume settings; those wanting bigger burrs or more throughput step up to the Mahlkönig E80S/E80 Supreme, while Mahlkönig's current commercial line has moved on to the E65W GbS with wireless Sync integration.

Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new grinder gets blamed for it. A balanced burr set: rotate origins freely — it will keep up.

Common questions
Is the Mahlkönig E65S GbW still sold new?
Mahlkönig's own product page lists this exact model as no longer available, having been succeeded by the E65W GbS (Sync) grinder, though open-box and dealer stock still circulate through specialty retailers.
How accurate is the grind-by-weight dosing?
Independent testing found deviations as small as about 0.2 grams under normal load, though some long-session owner reports note drift of a few percent that requires periodic recalibration.
Is this a good grinder for home use?
It can work at home if you want commercial speed and GbW precision, but its hopper-fed design, footprint, and price point are built around cafe volume rather than single-dose home habits.
Worth comparing

EK43S
The shop-counter version of coffee's most influential bulk grinder: same 98mm flat burrs and 1300W motor as the full EK43, just shorter so it fits under a cabinet. Built for cafes grinding retail bags and pour-over by the pound, and adopted by plenty of home fanatics who don't mind the footprint.
