Sanremo · Flat burrX-One
Sanremo's flagship commercial grinder uses a patented weigh-before-grinding system and 98 mm vertical flat DLC burrs to replace three separate grinders in one compact bar footprint — with near-zero retention and no purging required between doses.
The short version
The X-One is a serious commercial workstation grinder that trades price and complexity for genuinely novel dosing technology: beans are weighed before they touch the burrs, the chamber clears after every shot, and two hoppers plus a bypass drawer cover almost any café programme. The one thing a buyer must accept is a significant capital outlay — street prices run upward of $6,900 USD — and a reliance on complex electronics and a motor inverter that make long-term serviceability a real question for buyers outside a Sanremo dealer network.
Why people buy it
- Patented weigh-before-grind system eliminates post-grind dosing error and removes the need to purge between size changes
- Empty-chamber design means near-zero retention; each dose starts completely fresh with no stale carry-over
Why they don’t
- Street price of ~$6,900 USD places it firmly in the commercial tier — hard to justify for home use or small operators
The full tally
- Patented weigh-before-grind system eliminates post-grind dosing error and removes the need to purge between size changes
- Empty-chamber design means near-zero retention; each dose starts completely fresh with no stale carry-over
- Dual 1.2 kg hoppers plus a third bypass drawer effectively replace three separate grinders on one footprint
- 98 mm DLC-coated vertical flat burrs handle everything from espresso to French press without swapping hardware
- Street price of ~$6,900 USD places it firmly in the commercial tier — hard to justify for home use or small operators
- Complex electronics, touchscreen, motor inverter, and auger-feed mechanics add failure points that general technicians may not be able to service
- At 580 mm tall and 22 kg it is large and heavy; genuinely compact only compared to owning three separate grinders
What the community knows
Years of owner threads, distilled — the community is split.
Premium engineering and weigh-by-bean workflow genuinely shine, but electronic complexity, unproven parts longevity, and home-use-specific friction (dual hopper design, tall footprint, resale uncertainty) create real hesitation even among prosumers at this price point.

Worth knowing before you buy — Most serious buyers at this price ask: spend the same on a proven mechanical grinder plus invest heavily into espresso machine and accessories instead.
Known weak points — Electronic solenoid/touchscreen complexity concerns cited but not yet documented as widespread failures; dual-hopper mechanical wear unknown; parts availability unproven long-term.
“It's still a hopper (dual) machine with a limited ability to easily switch between more than 2-bean types, 23-inches tall! Has complex electronics, mechanicals and touch screens – all that I would want to run from.”
“The large 98mm burrs produce incredible coffees at all grind sizes and brew methods, and the innovative weigh-by-bean technology ensures a low retention workflow, seamless swapping between recipes, and easy cleaning.”
“Seems like every possible box is checked and it is truly an endgame grinder. Of course they are going for $6900.”

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Operators who outgrow a single-hopper on-demand grinder (Mahlkonig EK43S, Mythos 2, or similar) typically step up to the X-One when they need to consolidate regular, decaf, and single-origin grinding into one workflow with commercial-grade grind-by-weight accuracy. Downgrade rarely makes sense; owners who leave the X-One tend to be exiting commercial service or switching to a gravimetric machine system (e.g., Mahlkonig E65 GBW) where dealer support is broader.

Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new grinder gets blamed for it. These burrs lean bright — washed single-origins with real acidity are where they earn their price.

Common questions
What makes the X-One different from a standard grind-by-weight grinder?
Standard GBW grinders weigh the dose after grinding into a portafilter. The X-One weighs the beans before they enter the burrs, then grinds exactly that amount into a cleared chamber — so the dose precision is upstream of any grinding loss, and no purging is needed between shots or size changes.
Can the X-One handle filter coffee as well as espresso?
Yes. The 98 mm DLC flat burrs and wide RPM range (800–1500) are engineered for both espresso and filter methods. Baristas can save separate recipes per brew method and switch between them on the touchscreen without changing hardware.
Is the X-One suitable for home use?
Technically possible — it runs on 110 V / 60 Hz via its inverter — but at roughly $6,900–$7,500 USD, 22 kg, and 580 mm tall it is designed for commercial bars producing high daily volume. Most home users would find it over-specified and difficult to service independently.
How many recipes can the X-One store?
The touchscreen supports up to 12 custom recipes, each storing grind size (burr distance), RPM, and target dose weight. Recipes can also be uploaded and exported via USB.
What are the X-One's hopper capacities?
Each of the two main hoppers holds 1,200 g of beans. A third bypass drawer accepts loose beans for single-dose or specialty use — espressoparts.com states the hoppers dose 5–30 g per cycle.

Mahlkönig
EK43S
The shop-counter version of coffee's most influential bulk grinder: same 98mm flat burrs and 1300W motor as the full EK43, just shorter so it fits under a cabinet. Built for cafes grinding retail bags and pour-over by the pound, and adopted by plenty of home fanatics who don't mind the footprint.

Ditting
804 Lab Sweet
A Swiss single-dose lab/shop grinder built around 80mm cast-steel burrs tuned for roundness over sharpness — the burr set that put the word sweet into grinder marketing. Discontinued and replaced by the 807 Lab Sweet, but still floating around used and in cupping labs.
