Mahlkönig EK43 vs Option-O Lagom P100
Two grinders cross-shopped at the same money. The Lagom P100 is numbered 0–10; the EK43 is numbered 0–16.
Which to buy
Choose the
EK43 if you…
- grind from a full hopper — about 1,200 g
- grind straight into retail bags — it has a bag clamp
- want to buy new from Mahlkönig
Choose the
Lagom P100 if you…
- single-dose — retention under 0.1 g with or without RDT, Option-O says
- want to set burr speed, from 200 to 1,700 rpm
- want stepless adjustment with fine markings — each 0.1 line moves the burr 7.5 microns

The same number means different things
Both grinders use a numbered dial, which makes it tempting to copy a number straight across. Setting 5 sits at grind index 9 on the EK43 but 26.8 on the Lagom P100 — far enough apart to change the cup.
Converting a setting
If a recipe quotes a setting for one of these grinders, read across for the equivalent on the other. Rows are spaced evenly by grind size, not by dial number — on a conical burr those are not the same thing.

The shape of each dial
Where the connectors bunch, that grinder’s dial is compressed and single steps count for more. Comparing the two shapes tells you which gives finer control, and where.

Dialing in the EK43
The grinder that changed what filter coffee was supposed to taste like, and still the reference for high-clarity brewing. Its very large flat burrs produce an unusually narrow particle distribution, which is why coffee ground on an EK often tastes cleaner at the same nominal setting than it does elsewhere. Stepless, so treat the numbers as targets.
Dialing in the Lagom P100
A large flat-burr single-dose grinder aimed at people who want commercial burr size at home. As with the rest of the Lagom range, the burr set you fit changes the grind character more than the dial position does.
