The Short Version
The Mahlkonig E64ws offers near-surgical precision and auto-adjustments, but its app and lack of auto purge fall short, making it a powerful yet imperfect tool for espresso consistency.
In This Article
This might just change your routine: The Mahlkonig E64ws is a grinder that delivers unmatched consistency for espresso extraction. After five years of single dosing, I’ve finally found a machine that feels like an extension of my hands—until it doesn’t. The flat burrs deliver precision that’s almost surgical, but only if you’re willing to tweak the water temp from 94 to 92 degrees. Dialing in is a process, not a chore, and once you hit the sweet spot, it’s seamless. The auto grind adjustment, a recent update, is a game changer—it learns from shot times and adapts without micromanagement. Pair that with the auto portafilter feature, and you’ve got a setup that feels almost intuitive.

Precision Meets Progress
The E64ws isn’t just about speed; it’s about control. Unlike the Varia vs3, which felt like a guessing game, this grinder gives you tools to lock in results. The flat burrs, though, demand a calibration ritual. Lowering the water temp isn’t a hack—it’s a necessity. The machine’s ability to adapt to shot times is a critical feature for anyone chasing consistency. And let’s not ignore the portafilter’s auto-lock, which eliminates the fumbling of manual setups. It’s not perfect, but it’s closer than most.
Where the Grind Falls Short
The app, however, is a letdown. It’s a ghost in the machine—useless unless paired with their scale. No auto purge option? That’s a missed opportunity. But here’s the twist: some issues might be region-dependent. Vibration? None. Noise? None. The only complaints are software quirks that feel like a half-baked update. If you’re in the market, weigh those flaws against the precision you’ll gain.
