Option-O · Flat burrLagom 01
A 98/102mm flat-burr single-dose grinder built like a tank, aimed at the buyer chasing near-zero retention and lab-grade consistency across espresso and filter.
The short version
This is a giant-burr single-doser for people who have already owned three grinders and know exactly what they are chasing.
Accept the price, the size, and the fact that a 98/102mm flat burr trades some classic body for clarity, and it delivers benchmark consistency.
Why people buy it
- Exceptionally low retention and tight particle distribution for a burr this large, independently verified in lab testing
- Tool-less (near tool-less) disassembly that returns to the exact same zero calibration after cleaning
Why they don’t
- Loud in operation, measured around 89 dB in independent testing
The full tally
- Exceptionally low retention and tight particle distribution for a burr this large, independently verified in lab testing
- Tool-less (near tool-less) disassembly that returns to the exact same zero calibration after cleaning
- Genuine one-grinder-for-espresso-and-filter versatility, especially with the 102HU burr option
- Serious industrial build (CNC 6061-T6 aluminium, 1300W BLDC motor) meant to last decades
- Loud in operation, measured around 89 dB in independent testing
- Big and heavy for a home counter, and a full bag of beans will not fit under the hopper
- Entry price is high for a single-dose grinder and dialing in the alternate burr sets takes more effort than a simpler machine
What the community knows
Years of owner threads, distilled — strongly recommended.
The Lagom 01 commands respect in the serious espresso-and-filter segment for championship-proven engineering and single-dose precision, but premium price (CAD$3850) demands that skill and commitment justify it — it punches at the capability ceiling, not the value line, and the…

Worth knowing before you buy — Most owners wish they had bought it sooner if they were committed to single-dose espresso; few regret the price once skill catches up to the machine.

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — People land here from a Niche Zero, P64, or P100 once they've hit a wall on light-roast clarity or want one grinder to cover both filter and espresso duty. From here there isn't much further to go except lateral moves to other giant-burr rigs like the Weber EG-1 or Kafatek M98V — it's largely an endgame purchase rather than a stepping stone.

Before it arrives
What completes this grinder — the faded pieces can wait.
Coffee scale with timer — Espresso is a ratio. A 0.1g scale with a built-in timer is the single biggest consistency upgrade for any manual machine.

- Dosing cup — Pairs with single-dose grinding — grind into the cup, swirl, and transfer to the portafilter cleanly.
- Grinder cleaning kit — Brushes and grinder tablets keep retention and stale grounds in check.
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.

Is the Lagom 01 good for both espresso and filter coffee?
Yes, reviewers and owners consistently describe it as a genuine dual-purpose grinder, with the 102HU burr option in particular praised for switching cleanly between pour-over and espresso settings.
How loud is the Lagom 01?
Independent lab testing measured it at about 89.2 dB, making it one of the louder grinders in its class.
Worth comparing
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.
