Grind setting conversion
DF64 DF64 Gen 2 vs Option-O Lagom Mini
Two grinders cross-shopped at the same money. The DF64 Gen 2 is numbered 0–90; the Lagom Mini is numbered 0–50.
| DF64 Gen 2 | Lagom Mini | |
|---|---|---|
| Brand | DF64 | Option-O |
| Scale | Numbered dial | Numbered dial |
| Dial range | 0 – 90 | 0 – 50 |
| Burrs | Flat | Flat |
| Espresso → filter | 26 numbers | 18 numbers |
| Filter → coarse | 52 numbers | 20 numbers |
The same number means different things
Both grinders use a numbered dial, which makes it tempting to copy a number straight across. Setting 25 sits at grind index 11.3 on the DF64 Gen 2 but 49 on the Lagom Mini — 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.
DF64 DF64 Gen 2
Option-O Lagom Mini
Dialing in the DF64 Gen 2
A 64mm flat-burr single-dose grinder that became popular precisely because it puts commercial burrs at a domestic price. Espresso is the design centre; the burr choice you fit matters more to grind character than the dial does.
Dialing in the Lagom Mini
A compact single-dose grinder designed around burr swapping, so its character depends heavily on which set is fitted. Stepless. Low retention is the main reason to own it — it is built for people who change coffees constantly.
