Mahlkonig E64 WS & PUQ Press Gen 6 Mini Bundle

The Mahlkonig E64 WS is the pick for home espresso, and the Mahlkonig X54 suits home brewers who switch between espresso and filter. Both bring the brand's commercial grind engineering down to a footprint and noise level that fit a kitchen counter.

Grind-by-Sync on the E64 WS works two ways at home. Paired with Mahlkonig's Xenia espresso machine, the grinder reads each shot's weight and time and corrects the grind size for the next one. With any other espresso machine, the Mahlkonig Sync Scale does the same job: it weighs the shot under the portafilter and sends the result to the grinder over Wi-Fi through the Mahlkonig Sync app.

Mahlkonig lists the Sanremo and La Marzocco Sync machines alongside its cafe grinders, the E65 and E80 GbS models, rather than the E64 WS, so if you own one of those machines, ask a Crawford advisor before counting on a direct connection. Without Sync, the E64 WS still grinds by weight and you set grind size yourself.

Not for grind-by-weight. The E64 WS has its own scale in the portafilter holder and stops at your target dose without any accessory. The Sync Scale adds the other half of Grind-by-Sync: it weighs the finished shot and tells the grinder whether to go finer or coarser, so the grind keeps following your recipe as beans age.

If you own Mahlkonig's Xenia espresso machine you do not need it, because the machine measures the shot itself. Third-party espresso scales such as Acaia or Varia do not feed Grind-by-Sync. Crawford Espresso sells the Sync Scale on its own and as the E64 WS & Sync Scale bundle.

All five suit a home espresso bar. They differ in how they dose. The E64 WS weighs each dose on 64mm burrs and is the only one with Grind-by-Sync. The Mahlkonig X64 SD uses the same 64mm burrs but is a single-dose grinder with no scale, so you weigh beans yourself, which suits switching coffees often. The Mahlkonig X54 is a timed 54mm all-round grinder for espresso and filter at a lower price.

The Eureka Atom W 65 also grinds by weight, on 65mm burrs with a 1.2 kg hopper, but stands about 21 inches tall and weighs over 26 lb. The Fiorenzato AllGround Sense grinds by weight on 64mm burrs and handles filter as well as espresso. Choose the E64 WS for weighed espresso doses in the most compact grind-by-weight body here, with the option to automate grind adjustment later.

E64 WS grinders built after April 2026 ship with a redesigned metal flapper at the grind chute and an updated portafilter fork, both improved by Mahlkonig after the first production runs. Grinders shipped by Crawford Espresso come from the current batch.

The E64 WS uses 64mm special steel flat burrs, holds 250 g of beans, and measures 6.06 inches wide, 8.58 inches deep, and 15.35 inches tall with the hopper, at 12.8 lb. It runs on standard 100 to 120V household power at 200 W.

Grind-by-weight means the machine weighs the dose as it grinds and stops at the target weight, rather than running on a timer. Weighed dosing removes the drift that bean level and humidity introduce, so every dose lands on recipe without manual correction.
