In brief

The Lagom P100 is a single-dose grinder with 98 mm flat burrs in a body small enough for a home counter. Option-O says an offset design lets it fit burrs this large into a compact footprint. It grinds from French press to Turkish fine.

It is no longer in Option-O's shop. An archived US listing from September 2026 shows every variant sold out, and that listing now returns a missing page. Option-O has not announced a discontinuation or named a replacement, and its product page is still up.

That makes the P100 a used-market buy. It suits someone who drinks light roasts as espresso and filter and wants large burrs without a café-sized machine.

What it does well

  • Dickson Tan's 18 g in gave 18.0 g out, even without RDT
  • Auto mode stops the grinder and purges the chute when beans run out
  • Option-O says alignment is permanent, even after tool-free disassembly
  • Dickson Tan found espresso clear and forgiving, with no undrinkable shots

Where it falls short

  • Option-O's shop no longer lists it, so new stock is gone
  • Dickson Tan says the portafilter can vibrate off the fork
  • Shots run fast; Dickson Tan had to adjust his technique
  • Heavy for its footprint at 14.8 kg, per Option-O

What it does well

Retention is close to zero. Option-O claims under 0.1 g with or without RDT. Dickson Tan, reviewing his own P100, found that 18.0 g of beans gave 18.0 g of grounds without spraying.

The workflow is mostly automatic. Option-O fits two switches: an auto mode that stops and purges when beans run out, and a manual on/off. Tan valued the auto mode for removing a step.

Alignment is designed in. Option-O specifies critical parts to better than 0.01 mm and says the alignment is permanent. You can open the grind chamber without tools and keep your setting, according to Option-O.

It is fast and versatile. Option-O quotes up to 5 g a second at espresso fineness and variable speed from 200 to 1,700 rpm. Tan used it for both espresso and filter and described his filter brews as sweet, juicy and tea-like.

Where it falls short

It is no longer sold new, so a buyer depends on the used market and Option-O's support. Check the burr set fitted, since Option-O offered more than one.

The espresso style is specific. Tan says shots taste "closer to a concentrated filter than a traditional espresso," with less body. He also found shots ran fast and had to change his ratios and technique.

There are workflow niggles. Tan reports the portafilter can vibrate off the fork and cause a mess. He found the dosing cup flimsy and missed a hopper lid.

It is heavy. Option-O lists 14.8 kg, and Tan found it awkward to lift. Plan where it will live before buying.

Who should buy it, and who shouldn't

Buy one used if you single-dose light roasts, pull longer-ratio shots, and also brew pour-over. Tan gives it his highest recommendation for exactly that buyer.

Skip it if you want thick, traditional espresso from darker roasts. Skip it too if you need a hopper that holds a day of beans, or a grinder still under a new warranty.

How it compares

The Mahlkönig EK43 is the obvious reference: the same burr diameter, but a much larger café machine with a hopper. Mahlkönig EK43 vs Lagom P100 shows the two dials side by side.

The Kafatek Monolith Flat Max is a current 98 mm single-dose grinder, built to order. The Turin DF83 V2 gives up some burr size but is easier to buy new.

For a smaller-burr comparison, see DF64 Gen 2 vs Lagom P100. The grinder finder lists other current options.

Owning it

Routine cleaning needs no tools. Option-O says its lock-ring design opens the grind chamber in under two minutes without losing your setting. It recommends a routine clean once or twice a year; see how to clean a burr grinder.

Expect a break-in period. Tan noticed a foam smell at first that faded after a few weeks. If you change burrs, follow how to replace grinder burrs and recheck the zero.

Option-O says the burr chamber and motor are modular and can be separated for repair. It offers a one-year limited warranty and lifetime support. Your starting points for each brew method are in the settings chart.
