Grind Quality

The Lagom 01 is built around a flat steel burr set of either 98mm or 102mm, with the 102mm version using Mizen 102OM or SSP 102HU Blind Burrs.
Blind mounting — screwing the burr onto the motor shaft from behind — gives roughly 18% more usable grinding surface than a conventional carrier, and reviewers consistently report exceptionally uniform particle distribution.
Stepless adjustment moves in 7.5-micrometre increments at each major mark, and the entire range from espresso to filter sits within less than one full rotation, which makes dialling in precise but quick.
What you get in the cup is the modern flat-burr signature: high clarity, defined acidity, and a clean separation of flavour notes.
One long-term owner noted that the burrs needed around 50 pounds of seasoning before the profile settled into its potential — a real consideration if you are paying this much and want results from day one. Lower RPM settings on the 200–1,700 range narrow the particle distribution and emphasise clarity; higher speeds add body.
That tunability is genuinely useful rather than a spec-sheet checkbox.
Build Quality
Option-O machines the chassis from 6061-T6 aluminium and the 01 weighs 16kg, which sits on the counter like a small espresso machine. The review sample from Kaffeemacher came in at 15.3kg; the slight discrepancy comes down to burr carrier and accessories.
The footprint is 17cm wide by 30cm deep and 36cm tall — narrow, but tall and very deep, so you need to plan counter space accordingly.
Disassembly for routine cleaning is effectively tool-free: a thin pin releases the burrs, and once you reassemble, the grind setting returns exactly to where it was. No recalibration, no drift. The new adjustable zero-calibration system also removes the need for sticker-based reference marks. Everything feels over-engineered in the right way.
Workflow

This is where the 01 justifies a chunk of its price. Single-dose loading, magnetic 50g catch cup, optional magnetic portafilter holder, auto-purge, and auto shut-off combine into what owners describe as a near-perfect daily routine.
Retention is under 0.1g, which is essentially zero in practical terms, and the chute design keeps the path clear with just an occasional wipe on dry days.
One quirk worth flagging: the magnetic dosing cup is sized to reach under a wide chute, so it works well but looks ungainly compared with the sleeker Niche Zero or the pricier Weber EG-1.
The 01 has no anti-pop or anti-static system; static is mostly a non-issue with flat burrs at this size, but very dry winter conditions can leave a small amount of grounds clinging near the exit.
Noise
The 01 is loud. A 15g dose is pulverised in roughly one second, after which the motor spins up to purge, producing a short but intense peak. One owner reported sore ears and temporary ringing after a seasoning session without hearing protection.
The pitch is low and not unpleasant — less shrill than a Weber EG-1 — but this is a grinder you operate with earplugs if you are running back-to-back doses or seasoning fresh burrs.
Who It Suits

The Lagom 01 is an endgame grinder in the most literal sense: a single purchase intended to cover espresso, milk drinks, and filter for the next decade or more.
It suits someone who already owns a capable hand grinder such as the 1Zpresso K-Ultra and wants the convenience of electric without giving up grind quality, or a buyer stepping up from a Niche Zero or a DF83 V2 who wants bigger burrs, lower retention, and a more refined workflow.
It does not suit casual users. A 98mm flat burr at 2,500 dollars is obscene overkill for someone making a single daily V60.
One experienced owner put it bluntly: unless you regularly push extractions well beyond 2% TDS, or you specifically want the 01 for very long, low-ratio filter brews, a mid-tier flat or conical will land in the same flavour neighbourhood for a fraction of the price.
Value and Comparison
At the official 2,650 USD price, the 01 is the cheapest entry into true 100mm-class flat burr territory. The closest alternatives — EK Omnia, Weber EG-1, the various Titus options — all start noticeably higher or offer less refined workflows.
Against the Baratza Forte BG or the Eureka Mignon Specialita, the comparison is almost unfair: those are competent domestic machines, the 01 is a different category of object.
The honest value question is whether the jump from a 64mm or 80mm flat burr justifies roughly four figures of extra spend. For most home baristas, no.
For someone building a long-term setup around light-roast filter and modern espresso, and who will actually use the stepless, RPM-tuneable, ultra-low-retention workflow every day, the 01 is one of the more defensible ultra-premium purchases on the market.
Buy the Lagom 01 if you are an experienced home barista building a long-term, light-roast-focused setup and you will genuinely use the 98/102mm flat burr performance, stepless dialling, and near-zero-retention single-dose workflow every day. Skip it if you make one or two brews a day, do not push extractions hard, or simply want a solid electric grinder — a Niche Zero, DF83, or a strong 64mm flat will cover you for a tenth of the price.
