Option-O Lagom 01 – single-dose grinder with 102 mm flat burrs and PCS
Buy the Option-O Lagom 01 in Switzerland: single-dose grinder with 102 mm Mizen blind burrs, PCS pre-crusher and 200–1700 rpm. Partner of Option-O, Bern and Zurich.
The Lagom 01 is a flat burr grinder by Option-O for espresso and filter. The housing is CNC-machined, anodized aluminum, and all critical parts are made to 0.01 mm. Option-O names home use, the brew bar, the roastery and the coffee lab as its settings. According to Option-O, the Lagom 01 with Mizen 102OM burrs is a qualified filter grinder of the World Brewers Cup 2026 to 2029.
What defines the Lagom 01
Precision to 10 microns
The critical components are made to ±0.01 mm or tighter. The unibody housing keeps the stack-up of tolerances small, so the burrs are cleanly aligned to each other from the factory. Every critical part goes through quality control, and the precision is retained even after disassembly.
Very low retention with static reduction
According to Option-O, static reduction makes the Ross Droplet Technique (RDT) optional, even in dry air. It is maintenance-free and self-cleaning. The grounds fall evenly into the portafilter. Option-O still recommends a short distribution step, for example with a WDT tool. Typical dynamic retention: under 0.1 g.
Mizen burrs in XL blind burr format
Option-O developed the Mizen burrs in-house over about a year of testing, starting from a classic geometry and tuned for modern light roasts. As blind burrs they come only in 102 mm diameter. Without screw holes and with a slightly larger outer diameter, the effective grinding surface grows by about 18 percent compared with standard 98 mm burrs, in the same housing. According to Option-O, the goal is good aroma separation and a sweet, juicy cup.
Preliminary Crushing System (PCS)
The patented PCS feeds the beans evenly with an auger and pre-breaks them before they reach the burrs. In Option-O's tests, filter brews ran up to 15 seconds faster at the same grind setting, and for espresso the grind could be set 2 to 5 marks (8 to 37 µm) finer with otherwise identical parameters. Both point to fewer fines. Grinding takes 1 to 3 seconds longer, and peak motor load drops by up to 40 percent. Higher rpm increases the share of fully pre-broken beans. The PCS is only available with the 102 mm configuration.
Redesigned Chute Knocker
The knocker at the chute is magnetically assisted. A short press on the trigger releases remaining grounds from the chute, so the full dose ends up in the portafilter or cup.
The details in everyday use
Modular platform
The platform sits lower, which protects the base plate if a portafilter falls. From the factory it magnetically holds the included portafilter holder for 58 mm baskets or the included dosing cup. It can also be combined with shaker cups or tamping stations for other portafilter sizes.
Workflow for baristas
You add the beans, and the grinder does the rest. That includes auto-purge, automatic shut-off, speed control, stepless grind adjustment, static reduction and an easy-to-read scale.
Grind adjustment with zero point
You calibrate the zero point yourself, without stickers. The scale is easy to read from the front, in the espresso range as well as the filter range. A removable limiter prevents the burrs from being set below zero and restricts the adjustment range if needed. After disassembly for cleaning, the grind setting returns exactly to its previous position.
Durable and repairable
Option-O uses standard components wherever possible, including the motor. That makes maintenance and repair easier should a part ever need replacing.

Who the Lagom 01 is made for
For anyone who wants to grind espresso and filter with one grinder and dose single portions. Option-O tuned the Mizen burrs for light roasts. Burr sets are like engines: which one you prefer is subjective. That is our opinion, one of many.
You can find all models of the brand in our Option-O collection. A comparison with the Weber Workshops EG-1 and Lagom P80 is on EG-1 vs. Lagom P80 vs. Lagom 01. For anyone who wants to grind affordably and precisely, there are grinders from Varia and hand grinders from Comandante and Timemore.
The grinder pairs with a machine you can narrow down in our coffee machine advisory tool, for example from La Marzocco or a lever from Flair Espresso. Scales: compact and precise from Normcore, with app and flow-rate display from Acaia. WDT tool and puck screen are available from Normcore or from Weber Workshops. Financing available.
A free consultation appointment narrows down the choice. If you want to test several grinders side by side, book the espresso machine and grinder comparison in the showroom, in Zurich with Option-O among others. It is an option, not a requirement.
Frequently asked questions
What does the Preliminary Crushing System (PCS) do?
The PCS feeds the beans evenly and pre-breaks them before they reach the burrs. With it, Option-O measured filter drawdowns up to 15 seconds faster at the same grind setting and, for espresso, grind settings 2 to 5 marks finer with otherwise identical parameters. That points to fewer fines.
Which burrs does the Lagom 01 come with at your shop?
We carry the Lagom 01 with the Mizen 102OM blind burrs and PCS, in black or silver. Option-O also offers SSP 102HU blind burrs and the 98 mm configuration with screw mounting without PCS. If you are looking for one of these versions, write to [email protected].
Is the Lagom 01 suitable for filter and espresso?
Yes. The stepless adjustment ranges from French press to espresso, and the scale is readable from the front in both ranges. According to Option-O, the Lagom 01 with Mizen 102OM burrs is a qualified filter grinder of the World Brewers Cup 2026 to 2029.
Do I have to reset the grind setting after cleaning?
No. You can disassemble the grinder for cleaning and put it back together, and according to Option-O the grind setting returns exactly to its previous position. You calibrate the zero point yourself, without stickers.
What is included?
Option-O lists a magnetic portafilter holder for 58 mm baskets and a magnetic dosing cup. For portafilters in other sizes, the platform can be combined with tamping stations.
Can I see the Lagom 01 before buying?
In our showrooms in Bern (Gerberngasse 44) and Zurich (Hagenholzstrasse 50b) you can see a wide selection live, but not every model is set up at all times. Write to [email protected] before your visit. Delivery throughout Switzerland and to Liechtenstein in 2–4 working days, Click and Collect in Bern and Zurich.
Tip from the roastery: For espresso with plenty of body and for milk drinks, we roast Cozy Chocolate and Nutty Delight. If you are looking for maximum body without acidity, reach for Very Nutty. For the curious who enjoy something fruity, also as filter, there is Wild Peach. That is our recommendation, one of many.
