KoMo grain mills

KoMo mills were the heart of the old Natural Europe shop. This page replaces the original product listing with an independent overview of the current range, built from KoMo's own published specifications.

Who makes KoMo?

KoMo is an Austrian company from Tyrol. According to KoMo's own timeline, Peter Koidl began building grain mills under licence in 1985, launched his own Penningberger Kornmühlen (PK) designs in 1993, and registered the KoMo brand on 1 February 2002. The name stands for Koidl and Mock: the German mill designer Wolfgang Mock contributed his developments to the partnership from 2001 until 2014, when he left to concentrate on what became Mockmill.

KoMo belongs to a small cluster of Tyrolean and Salzburg mill makers (Osttiroler and Salzburger among them) that still build household stone mills by hand. Buy From Europe, our sister directory, keeps a list of companies based in Austria if you want to explore other makers from the same region.

KoMo mills are recognisable by their beech housings with traditional box joints, quiet 250–600 W motors and corundum-ceramic millstones that the maker describes as self-sharpening.

Approximate figures as published by KoMo (checked November 2026). Output is for fine wheat flour; coarse settings run several times faster. KoMo states a 12-year warranty on the models whose spec pages list one.

How to choose a size

  • One or two people, a loaf or two a week: Fidibus 21, Magic or Fidibus Medium. 500 g of wheat takes about five minutes on the finest setting.
  • Families, daily baking: Fidibus Classic or KoMoMio. Same 360 W drive and 85 mm stones; the Mio's 1.2 kg hopper holds a full kilo-flour bake in one fill, the Classic has the solid-beech joinery.
  • Batch bakers and big households: the 600 W Fidibus XL Plus mills about 200 g a minute, so a 2 kg weekly bake takes ten minutes instead of twenty.
  • Corn and legumes: dry popcorn maize, chickpeas and lentils work; run them through a coarse setting first, then again fine.
  • Never: oily seeds (flax, sesame, poppy, sunflower) or damp, sprouted grain that hasn't been fully re-dried. They smear and glaze the stones.

Caring for corundum-ceramic stones

Start the motor before you pour in grain and never close the stones fully while the mill runs empty. If flour comes out warm and slow, the stones have probably glazed: run a handful of hard wheat or rice on a coarse setting. Brush the milling chamber dry; never wash the stones. Spare stones, hoppers and switches are sold as parts by KoMo, so a mill rarely needs to be replaced.

KoMo or Mockmill?

The two brands share a designer. Wolfgang Mock worked with KoMo from 2001 until 2014, then left to concentrate on what became Mockmill. In practice the choice is less about “which inventor” and more about housing, hopper and how the mill lives in your kitchen:

  • KoMo’s current household range uses beech housings with box joints, 75–100 mm stones depending on the model, and hoppers from about 700 g to well over a kilogram. They are designed to sit on the counter as furniture.
  • The Mockmill 100 and 200 use a compact composite housing, 90 mm corundum-ceramic stones and a 1,100 g hopper. They take less space and, on the 200, a 600 W motor gives about twice the fine-flour output of KoMo’s 250–360 W Fidibus models (200 g versus about 100 g a minute, using each maker’s published figures).

If you already like the look of a wooden mill and bake for one or two people, a Fidibus 21, Magic or Medium is the usual KoMo starting point. If you want more throughput in a smaller footprint, compare those figures side by side in the grain mill comparison and read the electric grain mill buying guide.

Frequently asked questions

Which KoMo mill is best for a small household?

KoMo itself sizes the Fidibus 21 and Magic (250 W, 75 mm stones) and the Fidibus Medium for 1–2 people, and the Fidibus Classic and KoMoMio (360 W, 85 mm stones) for 3–5 people. All of them mill roughly 100 g of fine wheat flour a minute, so the real differences are hopper size, stone size, housing and price.

Do KoMo millstones need sharpening?

No. KoMo uses corundum-ceramic stones that the maker describes as self-sharpening. If they glaze, run a small amount of hard grain such as wheat or rice on a coarse setting.

Can a KoMo mill grind coffee or oily seeds?

KoMo lists coffee beans for the Fidibus Classic, but oily seeds such as flax, sesame or sunflower clog any stone mill. Use a flaker or a separate seed grinder for those.

Where are KoMo mills made?

In Tyrol, Austria. KoMo says production has run since the mid-1990s in partnership with a Tyrolean workshop where most employees are people with disabilities.

How does a KoMo mill compare with a Mockmill?

They share a designer (Wolfgang Mock worked with KoMo until 2014) but not a factory. KoMo mills are wooden-cased Austrian machines with a range of stone and hopper sizes; the Mockmill 100 and 200 are compact German composite mills with 90 mm stones and, on the 200, a more powerful motor.
