Option-O Lagom P64

What it does well

Retention is very low. Option-O claims under 0.2 g without RDT for most beans. Kaffeemacher measured 0.2 g of permanent retention and found no temporary retention, so the grinder empties almost completely.

Alignment is built in. Option-O says each critical part is held to ±0.02 mm or better and that alignment survives full disassembly. Kaffeemacher reports good reproducibility of grind settings and a very narrow particle distribution.

It is flexible. Speed is adjustable, and Option-O has sold several 64 mm burr sets for it, from espresso-focused to filter-focused. Kaffeemacher tested the Mizen 64ES set and found it convincing for both espresso and filter.

The build is serious for its size. Option-O specifies a CNC-machined aluminium body, a 300 W brushless motor and dual angular contact bearings. Kaffeemacher calls it "extremely robust" and measured the ground coffee at about 28 °C after six shots in a row.

Where it falls short

Static is the main complaint. Kaffeemacher says it "can practically only be used meaningfully with a water spray." Without it, an 18 g dose came out between 17.7 and 18.2 g.

Option-O's FAQ disagrees in part. It says the RDT step is optional after break-in for most coffees. Expect to need it with some beans, and plan for it either way.

Option-O calls it ultra-silent, but Kaffeemacher measured 83.8 dB and called it moderately loud. It did describe the sound as smooth rather than harsh.

There are smaller limits too. The portafilter fork only fits 58 mm portafilters, per Option-O. Kaffeemacher found that very light beans can occasionally block it at low speed, and it called the included WDT tool crude.

Who should buy it, and who shouldn't

Buy one used if you single-dose, switch between espresso and pour-over, and want flat-burr clarity in a small footprint. It rewards people who like tuning speed and burr choice.

Skip it if you want to fill a hopper and grind on demand all week. Skip it too if spraying beans before each dose sounds like a chore. Kaffeemacher would not use it in its beginner courses for that reason.

Because it is off sale, check which burr set a used unit carries. Option-O's FAQ lists SSP and Mizen sets, some espresso-focused and some for filter, so they suit different brews.

How it compares

The DF64 Gen 2 is the most common cross-shop: the same burr size in a single-dose body, and still sold new. See DF64 Gen 2 vs Lagom P64 for both dials side by side.

The Niche Duo is another current single-dose flat-burr choice. The Turin DF83 V2 steps up to larger burrs in a similar workflow.

If you are weighing it against a commercial machine, Mahlkönig EK43 vs Lagom P64 shows how different the two dials are. You can browse others in the grinder finder.

Owning it

Cleaning is quick. Option-O says the grind chamber comes apart in under two minutes and that returning to the prior setting is painless. Kaffeemacher found two hex screws give access to the burrs.

Option-O suggests routine cleaning once or twice a year; see how to clean a burr grinder.

Burrs are a standard 64 mm size. Option-O's shop lists Mizen 64 mm sets, though both showed as sold out. After a swap, follow how to replace grinder burrs and recheck your zero point.

Option-O offers a one-year limited warranty plus lifetime support, and says most part swaps can be done with its instructions. Option-O's shop also carries a notice for anyone buying a second-hand Option-O grinder, worth reading first.
