Its ultra-slim all-metal profile — aluminum body, wood accents, no plastic in the build — sits on a counter without claiming the footprint that most capable grinders demand as the price of admission. The magnetic dosing cup auto-aligns at the base for a clean, contained workflow that takes up no more room than the grinder itself. It is, by a meaningful margin, one of the most considered designs in its class.\u003c\/p\u003e\u003cp\u003eThe 38mm 6-core conical burrs are CNC-machined from high-nitrogen SUS420 stainless steel at HRC58 hardness — a spec that indicates burrs built to stay sharp through years of daily use rather than gradually degrading toward dullness. At 190 RPM driven by a 96W DC motor, the grinding speed is deliberately low: less heat transferred to the coffee during grinding, less fine particle generation, and a quiet operating level that makes early morning use something other than an event. The straight-through grinding path — bean in at the top, grounds out at the bottom — minimizes retention naturally, and the included bellows purge the remaining particles at the end of each dose.\u003c\/p\u003e\u003cp\u003eThe stepless adjustment offers 0.01mm precision across the full range from fine espresso to coarse French press — the resolution that fixed-step grinders approximate and stepless grinders actually deliver. Finding the exact grind size for a specific bean, a specific brew method, or a specific extraction target is a matter of small, precise movements rather than jumping between predetermined positions. The GU38 performs best for filter brewing — pour-over, drip, Aeropress — where the 38mm conical burrs produce consistent, clear results, and handles espresso capably for the home barista dialing in on a single-boiler or prosumer machine.\u003c\/p\u003e\u003cp\u003eTool-free burr access for cleaning, a removable burr set, and an included brush make maintenance straightforward. All coffee-contact parts are BPA-free. One-year hassle-free replacement warranty with 24\/7 customer service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct details:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e38mm 6-core conical burrs — CNC-machined high-nitrogen SUS420 stainless steel, HRC58 hardness\u003c\/li\u003e\n\u003cli\u003e96W DC motor | 190 RPM — low speed, low heat, low noise\u003c\/li\u003e\n\u003cli\u003e0.01mm stepless adjustment — infinite precision across the full grind range\u003c\/li\u003e\n\u003cli\u003eUltra-slim 3.5\" profile — all-metal aluminum body with wood accents\u003c\/li\u003e\n\u003cli\u003eStraight-through grinding path — minimal retention by design\u003c\/li\u003e\n\u003cli\u003eMagnetic dosing cup — auto-aligns for mess-free dosing\u003c\/li\u003e\n\u003cli\u003eBellows included — purges remaining particles at end of grind\u003c\/li\u003e\n\u003cli\u003eTool-free burr access for cleaning\u003c\/li\u003e\n\u003cli\u003eAll coffee-contact parts BPA-free\u003c\/li\u003e\n\u003cli\u003e1-year hassle-free replacement warranty | 24\/7 customer service\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhy we love it:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e3.5\" ultra-slim profile fits where most capable grinders cannot — the counter space problem solved without sacrificing build quality\u003c\/li\u003e\n\u003cli\u003eAll-metal aluminum body with wood accents — no plastic in the construction, a build that looks and feels as considered as it is\u003c\/li\u003e\n\u003cli\u003e38mm 6-core CNC conical burrs at HRC58 hardness — built to stay sharp through years of daily use\u003c\/li\u003e\n\u003cli\u003e190 RPM low-speed motor minimizes heat transfer and fine particle generation — the grinding speed that serves the coffee rather than rushing it\u003c\/li\u003e\n\u003cli\u003e0.01mm stepless precision finds the exact grind size that fixed-step grinders can only approximate\u003c\/li\u003e\n\u003cli\u003eStraight-through grinding path and included bellows keep retention minimal — single-dose workflow without significant carry-over\u003c\/li\u003e\n\u003cli\u003eMagnetic dosing cup auto-aligns for a clean, contained, mess-free workflow\u003c\/li\u003e\n\u003cli\u003ePerforms exceptionally for filter brewing — pour-over, drip, and Aeropress results are consistent and clear\u003c\/li\u003e\n\u003cli\u003eHandles espresso capably for the home barista working within the 38mm conical burr's considerable range\u003c\/li\u003e\n\u003cli\u003eTool-free burr access makes cleaning a routine rather than a deterrent\u003c\/li\u003e\n\u003cli\u003eBPA-free throughout — nothing in the grinding path that shouldn't be near coffee\u003c\/li\u003e\n\u003cli\u003eThe entry point into single-dose grinding done properly — and a genuinely capable daily grinder at that\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eNative Manor Note:\u003c\/strong\u003e The GU38 occupies a specific and honest position in the Geimori lineup — between the portable T38 and the flat-burr GU64, it is the countertop grinder for the home brewer who wants single-dose workflow, real build quality, and stepless precision in the smallest possible footprint. It excels at filter coffee and handles espresso with care and attention — the grinder that rewards the brewer who is learning what dialing in actually means, without the investment the GU64 represents. At 3.5\" wide in an all-metal body that looks like it belongs on the counter, it is also, by a considerable margin, one of the best-looking grinders at its price point. That matters too.\u003c\/p\u003e","brand":"Wirsh","offers":[{"title":"Black","offer_id":63618187526513,"sku":"SLCG202605B","price":179.99,"currency_code":"USD","in_stock":true},{"title":"White","offer_id":63618187559281,"sku":"SLCG202605W","price":179.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/7221\/4641\/files\/Geimori-GU38-Black-Side_dcdfd84e-dc96-4620-990b-0e5afecf437c.jpg?v=1778921846","url":"https:\/\/nativemanor.co\/products\/geimori-gu38-single-dose-coffee-grinder-electric-burr-coffee-grinder-with-38mm-conical-burrs-stepless-adjustment-zero-retention","provider":"Native Manor","version":"1.0","type":"link"}
