About the Hario Mini-Slim Pro

The Hario Mini-Slim Pro is a manual hand grinder with 38 mm conical burrs and stepped adjustment. At its coarsest it reaches about 1000 µm, so Percolator and French Press sit partly beyond its range. Each click moves the grind by roughly 50 µm.

Methods the Hario Mini-Slim Pro covers

All 18 are worked out from this grinder's range and burr geometry. Its maker doesn't publish settings, and nobody has measured it that we can cite. Start there and adjust to taste.
