Fenwick M2 grinder review
ReviewsFlat burrs, stepless adjustment, and a hopper that holds too much.

Intro
A grinder is the part of the setup that decides how your espresso tastes. The M2 is the cheapest flat-burr option here with genuinely stepless adjustment.
Adjustment
Stepless means you can land between settings, which matters more than the burr material at this price. The collar has enough friction to stay put.
| Spec | Value |
|---|---|
| Burrs | 58 mm flat |
| Adjustment | Stepless |
| Hopper | 250 g |
| Retention | ~1.4 g |
Retention
Around 1.4 g stays in the chamber, so single-dosing needs a purge shot or a bellows. Not a dealbreaker, but plan for it.
Verdict
The right first upgrade if you already own a decent machine and cannot work out why your shots move around.
