Option-O Lagom 01 - Coffee grinder

Option-O Lagom 01 – 102mm Single-Dose Grinder with Pre-Crushing System

You put 18 grams of light roast beans into the hopper. You press the button. Before the burrs even start working, you hear the PCS – a short, controlled crunch, the pre-crusher breaks down the whole beans into uniform fragments. Only then do they fall onto the 102mm Mizen Blind Burrs. The brushless motor pulls through smoothly, without any drop in RPM. Six seconds later, 18 grams are in the magnetically held cup. You tap the chute knocker once, and the rest falls cleanly. You set up a pour-over, same grinder, same grind size range – just a few clicks coarser. What comes out tastes clearer and sweeter than what you're used to from 98mm grinders. That's not imagination. That's 18 percent more grinding surface and a pre-crusher that prevents beans from arriving chaotically at the burrs.

The Lagom 01 is Option-O's flagship – a single-dose grinder that combines two things that previously didn't exist in this combination: 102mm Blind Burrs (instead of the industry-standard 98mm) with an 18 percent larger grinding surface, plus the patented Preliminary Crushing System (PCS), which breaks down whole beans into uniform fragments before they reach the burrs. Coffee Coaching Club is a partner of Option-O and carries the Lagom 01 in both available configurations.

The Preliminary Crushing System – why the burrs only work after it

Anyone who honestly looks at an espresso grinder always finds the same compromise: whole beans hit the burrs uncontrollably. They come in bursts, pushing more on one side than the other, and the motor reacts with load peaks. The result: a proportion of very fine particles (fines) that doesn't come from the desired grind but from this chaotic entry.

The PCS addresses exactly that. An auger-like mechanism guides the beans controllably into a pre-crusher, which breaks them down into smaller fragments before they reach the 102mm Mizen Blind Burrs. What Option-O measured in its own tests: drawdown times for filter coffee are up to 15 seconds faster at the same grind size – a clear indication of fewer fines and a more uniform particle distribution. For espresso, the grind can be pulled two to five clicks finer (8–37 microns) with otherwise identical parameters. This doesn't mean that every bean automatically tastes better. It means the grind size range in which you can work cleanly becomes larger. Our observation in the showroom: The effect is most clearly noticeable with light roasts, and more subtle with classic dark espressos. This is one perspective, one of many.

As of April 2025, the PCS is pre-installed at the factory on all Lagom 01s with 102mm Blind Burrs. The PCS is not available for the 98mm configuration – the 98mm burrs use a different carrier mechanism.

Mizen Burrs – developed for modern light roasts

Option-O developed the Mizen burrs in-house, with a clear focus: light roasts, single origins, fruity profiles. After a long testing phase, the geometry and surface properties have been optimized for a sweet, juicy cup characteristic with clear aroma separation. Anyone addicted to the subtle nuances of a light bean – peach, bergamot, black tea – will find more of it on the Lagom 01 than on a typical 98mm espresso grinder.

Three burr configurations are available. The 102mm Mizen Blind Burrs (Option-O recommendation) utilize the full PCS, have ~18 percent more grinding surface due to the elimination of screw holes, and deliver the lowest retention. The 102mm SSP HU Blind Burrs are an alternative for those seeking a brighter, clearer profile with a bit more acidity – compatible with the PCS. The 98mm Mizen-OM (with screw mounting) is the right choice if you want to remain flexible and leverage the broader 98mm burr market – without PCS, but with access to all 98mm third-party sets.

Tool-free disassembly and Zero-Calibration

What's surprising in the showroom: You can completely disassemble, clean, and reassemble the grinder without tools – and your grind size will be exactly where it was. The Zero-Calibration system remembers the position, no stickers, no notes, no re-searching for the sweet spot. The grind size indicator is located at the front and is clearly legible even in extreme ranges (very fine for espresso, very coarse for French Press). A removable safety limiter protects the burrs from accidental adjustment below zero.

Variable RPM and magnetic modular platform

The brushless DC motor (1300W peak power) delivers variable speeds from 200 to 1700 RPM. Lower RPMs (around 400-600) reduce thermal stress and are particularly interesting for very light roasts. Higher RPMs (around 1200-1500) increase the proportion of fully pre-crushed beans before the burrs – the RPM thus becomes an additional tool for cup characteristics, not just for speeding up the grinding process.

The modular platform at the bottom magnetically accommodates either the included 58mm portafilter holder or a dosing cup. Aftermarket holders and alternative portafilter sizes can be retrofitted. The lower height reduces the risk of damaging the platform when clamping.

Who is the Lagom 01 for?

The Lagom 01 is for anyone who wants a flagship-level tool and whose focus is on light roasts, single origins, and fruity profiles. Those who want to resolve the compromise between espresso and pour-over – both from the same grinder, both at a high level – will find the Lagom 01 a tool that uncompromisingly fulfills both tasks. Cafés and roasteries looking for a specialized grinder for their single-origin programs that doesn't have to run parallel to the standard espresso grinder but takes on the main work.

The Lagom 01 is not for everyone. If you are looking for classic dark espressos with a dense body and creamy crema, a Weber Workshops EG-1 with CORE burrs offers a different characteristic – more body, more crema, less aroma separation. If you want 80mm in a more compact form: Option-O Lagom P80 with 80mm Mizen burrs and a 500W motor. If you want 58mm variability and 63mm compatibility in one grinder: Varia VS6 (exclusive Swiss importer). A detailed comparison of endgame options is available at EG-1 vs. Lagom P80 vs. Lagom 01.

The Lagom 01 is the grinder for anyone who knows what 102mm Blind Burrs and a pre-crusher are good for – and for anyone who wants to try it. If you want it, you know why.

What goes well with it

The Lagom 01 shows its potential with thermally stable machines that cleanly extract light roasts. La Marzocco Linea Mini R with a saturated grouphead and brew-by-weight is the natural combination – both devices rely on stability with small variables. The La Marzocco Linea Micra or the GS3 are also suitable partners. For manual lever extraction with precise grind control: Flair Espresso 58+2 (exclusive Swiss importer).

For brew-by-weight (on the La Marzocco Mini R via connected scale license): Acaia Lunar in the USB-C version. For a standalone espresso scale with app and flow rate display: also Acaia Lunar. For puck prep: Weber Workshops Moonraker as premium or Normcore WDT Tool as an affordable option (exclusive Swiss importer). For airtight bean storage: Airscape. For precise coffee water: Apax Labs mineral concentrates (exclusive Swiss importer). Background information on burrs, pre-crushing, and particle distribution in our Sensorics World.

Frequently asked questions

What does the Pre-Crushing System (PCS) really do?

The PCS breaks down whole beans into uniform fragments before they reach the burrs. Option-O has measured significantly faster drawdown times for filter coffee (up to 15 seconds) and a wider usable grind range for espresso (2–5 clicks finer possible). This indicates fewer fines and a more even particle distribution. In the cup: noticeably more clarity and sweetness, especially with light roasts. With classic dark espressos, the effect is more subtle.

What is the difference between the 102mm Mizen Blind Burrs and the 102mm SSP HU?

The Mizen Blind Burrs (Option-O recommendation) deliver a sweeter, juicier cup characteristic with balanced aroma separation – more forgiving during dial-in, ideal for all-round use. The SSP HU Blind Burrs deliver a brighter, clearer profile with present acidity and punchy characteristics – requiring a bit more care during dial-in, but yielding very clear aromas. Both use the PCS and are suitable for both espresso and filter.

When does the 98mm configuration make more sense?

If you already use a collection of 98mm third-party burrs or want maximum flexibility in burr selection. The 98mm configuration does not use the PCS – the grinding characteristics are closer to classic 98mm grinders. For most buyers, we recommend the 102mm configuration with PCS.

How loud is the Lagom 01?

Comparatively quiet thanks to the brushless DC motor and the CNC aluminum unibody. In our showroom, the Lagom 01 runs during tastings without disturbing conversations.

What does Zero-Calibration mean in practice?

You can completely disassemble the grinder (e.g., for cleaning or burr changes), reassemble it, and the grind size will be exactly where it was before. No stickers, no marking with a pen, no re-dialing in. This is a practical difference in everyday use that only becomes truly noticeable after a few months.

Is the Lagom 01 suitable for filter and pour-over?

Yes. The stepless adjustment covers espresso to French Press. With the Mizen Blind Burrs and the PCS, it functions as an all-rounder that covers both worlds equally well – this is one of its central strengths compared to espresso-specialized grinders.

Can I see the Lagom 01 before purchasing?

Yes. The Lagom 01 is in daily use in the showrooms in Bern (Gerberngasse 44) and Zurich Oerlikon (Hagenholzstrasse 50b). Bringing your own beans is welcome – PCS behavior and Mizen characteristics are best demonstrated with your favorite beans.

How quickly is the Lagom 01 delivered in Switzerland?

2 to 4 working days throughout Switzerland and to Liechtenstein. Click and Collect in Bern and Zurich. Financing available through Heylight.
