Option-O · GrinderLagom Mini 2
The most compact precision electric grinder on the market — a single-dose, all-metal, USB-C powered conical with near-zero retention that pulls double duty as a travel and countertop minimalist grinder for filter and light-duty espresso.
The short version
A purpose-built single-doser that proves tiny can be serious: all-metal CNC construction, P5-grade bearings, and genuine omni-range capability in a footprint smaller than most hand grinders.
Accept the strict duty cycle, the unmarked stepless dial, and the slow grind speed at espresso settings — this is a 1-2 cups-per-session machine, not a batch workhorse.
Why people buy it
- Smallest footprint of any electric grinder we know of (65 × 95 mm base) with a genuine all-metal, anodized build that should last years
- USB-C PD3.0 power means one less proprietary brick — runs from a laptop charger or power bank for genuine travel use
Why they don’t
- Strict duty cycle (90 s rest between shots, 30 min rest after 6 min cumulative grinding) makes it unsuitable for pulling more than a few consecutive doses
The full tally
- Smallest footprint of any electric grinder we know of (65 × 95 mm base) with a genuine all-metal, anodized build that should last years
- USB-C PD3.0 power means one less proprietary brick — runs from a laptop charger or power bank for genuine travel use
- Near-zero retention and strict single-dose workflow eliminate purging entirely, which matters when rotating expensive small bags
- Mizen 48MS conical burrs cover the full range from espresso to coarse filter with medium-high clarity
- Strict duty cycle (90 s rest between shots, 30 min rest after 6 min cumulative grinding) makes it unsuitable for pulling more than a few consecutive doses
- Espresso grind is slow — roughly 45–60 seconds for 18 g — and the unmarked stepless dial requires a personal notation system to repeat settings
- Not ideal as a primary grinder for very light roast espresso; Option-O themselves recommend the Lagom Casa for that use case
What the community knows
Years of owner threads, distilled — well regarded.
Excellent conical grinder for filter and light espresso work with thoughtful design refinements (USB-C, burr carrier, auto-shutoff) and strong build quality, but duty-cycle limits and modest espresso performance cap its appeal — best for owners who've already committed to…

Worth knowing before you buy — Most owners wish they'd sized up to a single-dose platform if serious espresso is the goal — the Mini 2 shines for filter and manual lever work.
Known weak points — Duty-cycle constraints under sustained espresso grinding; motor thermal limits documented in extended grinding sessions
Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners who primarily pull espresso — especially very light roasts — tend to outgrow the duty cycle and grind speed and step up to the Lagom Casa or Lagom P64. Filter-focused owners who need faster throughput often move to a larger single-dose flat-burr grinder.

Common questions
Can the Lagom Mini 2 grind for both espresso and filter coffee?
Yes. The stepless adjustment covers the full range from fine espresso to coarse filter. However, Option-O notes that if very light roast espresso is your primary use, the Lagom Casa is a better choice. Espresso grind for 18 g takes roughly 45–60 seconds at the machine's ~200 RPM.
What power supply does the Lagom Mini 2 need?
It requires a PD3.0-compliant USB-C adapter rated at 20V / 5A (100W). A standard USB-C phone charger will not work. It accepts 100–240V universally, and can also run from a compatible power bank.
What is the duty cycle, and why does it matter?
Allow at least 90 seconds of rest between grind cycles, grind no more than 4 shots within a 10-minute window, and rest at least 30 minutes once cumulative grinding has exceeded 6 minutes. This limits the grinder to low-volume home use and rules out entertaining or batch grinding.
Are the Mini 2 burrs compatible with the original Lagom Mini?
No. The Mizen 48MS burrs in the Mini 2 use a different mount system and are not backwards compatible with the first-generation Lagom Mini.
What is the retention like?
Option-O targets less than 0.2 g retention. No purge dose is needed when switching beans or grind settings.
