Designed around grind-by-weight precision and high-speed espresso preparation, the Eureka Mignon Stark W Coffee Grinder combines Eureka’s patented weighing technology with 65mm diamond-treated flat burrs and a commercial-style AC motor in a compact home espresso format. Built for users who want tighter dose consistency and faster workflow, the Stark W focuses heavily on repeatability, low retention and quieter daily operation.

Instant Grind-by-Weight

The Stark W uses Eureka’s patented Instant Grind Weighing Technology to weigh coffee during grinding rather than relying purely on timed dosing. Factory pre-calibrated from first use, the system is designed for fast setup and dose consistency within ±0.2g while remaining stable against vibration, accidental knocks and uneven bench surfaces during daily operation.

Diamond Burr Performance

At the centre of the Stark W are 65mm diamond-treated flat burrs paired with Eureka’s high-performance AC motor platform. The blind upper burr design removes screw holes from the grinding surface to reduce retention and improve grind consistency, while the diamond treatment helps maintain burr sharpness and stable particle distribution over significantly longer use periods.

Built for Espresso Workflow

The Stark W combines Eureka’s oversized King Size Grind Dial with a 2.8” touchscreen interface for precise grind adjustment and simplified dose programming. Three programmable doses, continuous mode and a lock function are built directly into the display, while the heavy-duty universal fork supports a wide range of portafilter styles, including bottomless portafilters.
