Mahlkönig E65S GbW vs Mazzer Kony S
Two answers to the same question — the split below is the whole argument.
Mahlkönig
CA$3,199–3,999 · US$2,300–2,800
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…

Mazzer
CA$3,200–3,450 · US$2,500–3,600
This is a café workhorse, not a kitchen-counter single-doser: 63mm conical burrs at low RPM buy you thermal stability and dose consistency shot after shot through a rush. Accept the size, th…

Where they actually differ
Measured side by side, they tie on all 6 counts we track — the choice is price, size, and taste in hardware.
The E65S GbW leans the balanced middle; the Kony S leans syrup and body. Pick the cup, not the machine.
The counter’s vote
Looks barely figure in either machine’s record — the counter can sit this one out.
E65S GbW: Minimalist commercial form (stainless steel, compact depth) wins kitchen-approval on professional look; color-lock hopper is thoughtful but not praised as a design highlight.
Kony S: Functionally transparent industrial design — no design-purchase pull, neutral counter presence; buyers cite engineering reputation and cafe heritage, never aesthetics.
Where they tie: espresso duty · brew range · reliability record · built to last · value per dollar — don’t let a spec sheet invent a difference.
So — which one?
Take the E65S GbW if —
- Bright, separated cups are the goal
Take the Kony S if —
- Syrupy, traditional cups are the goal
The data cannot split them. Take the cheaper one, or the one whose looks you can live with — then stop reading reviews.
Known weak points
E65S GbW
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.
Kony S
High retention requires manual chaining or single-dosing workaround; conical burrs slow to dial on espresso (<0.5g micro-steps difficult); motor noise and ventilation design common minor complaints in residential spaces.
