Breville Smart Grinder Pro vs Kinu M47 Classic
Convenient electric versus heirloom manual. The Breville Smart Grinder Pro at $200 grinds into the portafilter with timed dosing — fast but high-retention with more fines. The Kinu M47 Classic at $349 is an all-steel German hand grinder with a 10-year warranty and precise, durable grinding, by hand. Choose the Breville for convenience and price; choose the Kinu for build quality, longevity, and grind precision.

The Smart Grinder Pro is hands-free convenience: 60 settings, 0.2-second timed dosing, grinds into the portafilter, good for daily multi-cup use. The Kinu M47 Classic is a precision manual grinder machined entirely from solid stainless steel in Germany, with 47mm conical burrs, a 0.01mm bearing tolerance, a tactile stepless click ring, and a 10-year warranty — the build-quality and longevity benchmark among hand grinders.
Grind quality and durability favor the Kinu. The Breville's high retention (~18g in, 16g out) and excess fines hurt espresso consistency; the Kinu's tight tolerances and stepless adjustment produce cleaner, more precise espresso grounds, and its all-metal body is effectively indestructible. The trade is manual effort and a 35g capacity.
Convenience and price favor the Breville. At $200 versus $349, it's cheaper, grinds at a button press, doses by time, and handles filter and espresso for a household. The Kinu is for someone who values craftsmanship, a decade-plus warranty, and grind precision over speed, and doesn't mind hand-grinding every dose.
Buy the Smart Grinder Pro ($200) for hands-free convenience and a lower price. Buy the Kinu M47 Classic ($349) for heirloom build quality, longevity, and precise manual grinding.
