The KoMo Mio Grain mill is my new grain mill. Whole grain baking is best done with FRESH milled flours straight from the grain. That’s how the highest level of nutrition is received from the grains. A grain mill like the KoMo Mio is an essential kitchen tool for serious bakers.

FULL DISCLOSURE: Pleasant Hill Grain gave me this KoMo Mio grain mill for a fair and honest review and to help them launch this new product with a GiveAway. We are SO excited to help launch this amazing mill!
KoMo Mio Grain Mill Review:
If you are a long time follower of our blog you will know I have deep dived into Artisan Sourdough bread baking in addition to making my other yeasted breads. Now I’m excited to take my baking up to the highest level of creativity and nutrition by blending the freshest flour blends for all sorts of delicious breads and cereals. Are you a whole grain baker? Do you want to get really creative with flour blends? This mill may be a great fit for you!
When Pleasant Hill Grain approached Kayti and I about helping them launch their KoMo Mio Grain Mill I was all ears.
The KoMo Mio is a big step up in useability from my old impact mill. Here’s why I like this mill:
- It’s very easy to use and requires no special cleaning. Just dust it off as necessary.
- The KoMo will grind a large variety of whole grains and beans into flours and cracked cereals. That makes it very versatile for lots of different uses from making your own cereals and muesli to an infinite variety of flours you can blend just before baking for the BEST nutrition possible.
- It is MUCH quieter than my old mill
- The flour comes out the spout in front rather than blowing out the sides due to its wonderfully well constructed cabinet.
- It’s pretty sitting on my counter and doesn’t take a lot of room. So It’s always handy to use.
I put the KoMo Mio through its paces. I’m VERY satisfied with it. Watch my YouTube Review!
I spent decades making my own flours and baking whole wheat breads for our family with my old impact mill. Then the kids grew up, my lifestyle changed and the homemade breads went down the list of priorities. Now I’m baking bread again and loving it!
My first bread made with KoMo Mio milled whole wheat flour:
I’m adding sourdough artisan breads and recipes into our diet. I am thrilled to get back into milling flour blends and exploring more delicious recipes. Both the long cold rise artisan breads and the quicker yeast breads. You will be seeing more bread and whole grain recipes on the blog in the future.

I’ve got a loaf of our whole wheat sourdough bread rising in the fridge now. I ground the flour from whole wheat berries in my KoMo Mio mill. I’m using a finer pastry flour milling to create a lighter flour with our hard red wheat. Are you a kitchen scientist? This is Foodie fun!
I have never seen a grain mill with this newer, more modern two tone look. Now that I have it unboxed and sitting on my counter, I just love it. The construction of this mill is superb, eco friendly and it’s very pretty.
Benefits of adding Arboblend to the construction of this mill:
What is Arbolend? Look at the colored parts of the Mio (the white and red on this mill). THOSE ARE the Arboblend components of the KoMo Mio grain mill.
- Arboblend seals the grain mill in a better way than wood because it’s a liquid wood plastic blend that is MOLDABLE for a better fit and seal than wood can give. The flour stays IN the mill until it comes out the spout.
- Arbolend is eco-friendly too. I applaud and support sensible efforts to reduce the plastic in our oceans and landfills. Arboblend is completely biodegradable. So when I look at the two toned styling on this Mill I appreciate it.
- Arboblend is lightweight (Thank you KoMo!)
- Finally, For a grain mill of this quality The KoMo Mio has VERY low pricing largely due to the use of Arboblend.
- A lifetime mill: The excellence of engineering and construction that goes into every KoMo electric grain mill means that your mill can be expected to last a lifetime in normal use. Only the finest materials are used to make KoMo mills, and the European beechwood used in crafting their beautiful cabinetry is sustainably harvested.
The KoMo Mio Grain Mill Review:
I’m Falling more in love with this grain mill each time I use it. It’s SO easy to use and clean. Watch our KoMo Mio unboxing video and our KoMo Mio review video in this post to see it in action.
This grain mill is highly crafted with a sleek European two toned look and is made with eco friendly biodegradable materials.
For more in depth information on the KoMo Mio visit the “Pleasant Hill Grain website.

I researched the KoMo Mio company before I agreed to this give a way. The KoMo grain company are one of the best in the industry, in my opinion. They make wonderfully high quality grain mills out of eco friendly materials and the company has a decidedly environmentally friendly approach to their business. That excited me and so do all the great reviews I read on their mills.
Pleasant Hill Grain company is a company Homemade Food Junkie supports. Great products and Customer Service.
A small family run company from the heart of Nebraska with excellent, responsive customer service. They also are a full line kitchen shop with products that promote a healthy foodie lifestyle. My kind of place!

There are accessories available to make this grain mill even more awesome. Take a look at their KoMo Mio Product page for more details.
- A grain sifter is available to keep your flour grind evenly textured.
- Also, for our gluten free friends this grain mill has an insert to prevent contamination of the different flours.
Features:
- Grinds super fine flour
- Quickly adjusts to coarse grinds and cracked cereals too
- Solid beechwood & Arboblend Cabinet is well sealed against flour leaks
- Long life corundum-ceramic burrs
- Virtually no cleanup required
- Optional gluten-free grinding liner
- Long 12 year U.S. warranty
- Handmade in Germany

- The Mio is easy to set up and use. Plug it in, choose your grind setting and pour in your grains or beans. Don’t forget to set a bowl under the spout to catch your flour!
- The construction of this grain mill is LOVELY. It’s VERY well built and should last many many years.
- The grain mill is well sealed and made with Eco Friendly bio-plastic seams and it’s solid .
- The grain hopper is large and stable with a lid heavy enough to hold the ricocheting grains as they bounce around in the bowl.
- Clean up is very easy. Just wipe it with a cloth and put it away.
- The manufacturer says this mill will not need to be opened to adjust the ceramic grinding stones. They come perfectly placed and aligned. BUT you can open it easily for whatever reason, So Yay!
The only con I found to this mill is that the grain hopper (wooden bowl on top) was initially difficult to turn to adjust the grind setting. As I have used the mill several times the bowl is getting much easier to adjust. So this is a heads up if you’re wondering how to turn that bowl. Use two hands and twist firmly. It will loosen up with a few uses.

Thanks for this review. I’m considering purchasing one but have a few questions-Does the Arboblend touch the grain in any part of the process or is the Arboblend solely placed on the outside of the mill? What materials touch the grains during the whole process? Is this mill the exact same as the KoMo classic but just using the Arboblend instead of wood?

Hi kk, I used chat GPT to answer this since I did not know the answer. Here is what chat replied to your question:1. Q:Does Arboblend ever touch the grain during milling? A;No. Arboblend does not contact the grain during the actual grinding process: Arboblend® is used in the external housing and trim of the mill (e.g., the body panels, lid, and exterior parts of the hopper) but not inside the grinding chamber where the grain is processed. Loewen META trading GmbH +1 Q: What materials touch the grains during the whole process? A;The interior surfaces that come into contact with the grain — that is, where the grain passes through — are the hopper interior, the grinding stones, and the grinding chamber. Arboblend remains on external surfaces and doesn’t serve as a food contact surface during milling. The Stone Mill | So: Arboblend is solely part of the exterior structure, not a material the grain touches when it’s being ground. 2.Q: What materials do touch the grains during milling? A:When you grind grains, the following materials are involved in direct contact with the grain and the flour output: Corundum-ceramic grinding stones (burrs) — these are the actual milling surfaces. Grains are crushed between these stones into flour or meal. Loewen META trading GmbH Beechwood hopper interior — the grain sits in and flows down from the hopper. The visible wood surfaces inside the hopper contact the grain before it enters the stones. Loewen META trading GmbH Food-safe plastic or similar liner inside the grinding chamber — many KoMo mills have a BPA-free plastic component around the grinding path that prevents grain from hitting the housing directly. Several product specs list the grinding chamber materials as such. The Stone Mill | Arboblend does not contact the grain — it is an external biodegradable material used for the casing aesthetic and structural trim. 3.Q: Is the KoMo MIO the “same as Classic” except for Arboblend? A; Effectively, yes — with a few noted differences: Commonalities between Mio and Classic: Both use corundum-ceramic grinding stones, the same grinding technology and grain contact surfaces. KoMo - Shop Both have infinitely adjustable grind settings and similar power/milling rates (~360 W, ~100 g/min for fine flour). KoMo - Shop Both are designed for the same home milling use cases and cover similar grain types. KoMo - Shop Differences: Housing materials: Classic is typically solid wood throughout the exterior casing, giving a traditional, higher-end appearance. KoMo - Shop Mio uses a combination of wood and Arboblend bioplastic trim on its exterior surfaces (including the lid and edges) for design, color options, and sustainability. Loewen META trading GmbH Hopper size: According to manufacturer comparison sheets, the Mio often has a slightly larger hopper capacity (e.g., ~1200 g vs ~1000 g). KoMo - Shop User discussions from independent forums also reinforce that the internal mechanism (stones and motor) is essentially the same in both models, with the main differences being housing materials and aesthetics. Reddit Summary Aspect KoMo MIO KoMo Classic Grain-contact materials Corundum-ceramic stones, beech hopper, food-safe interior plastic Same Arboblend present? Yes (external housing trim) No Does Arboblend contact grain? No N/A Internal grinding mechanism Same as Classic Same Aesthetic and materials Modern with Arboblend & wood combo Traditional solid wood
I hope this helps you! FYI: I still have my koMo Mio mill and after years of use it still works great!

I am looking at this mill among others. It looks great, but my concern would be the one con you mentioned about it being tough to turn the grind setting. I have a mild disability but it gives me a weaker left side, and I worry that I could not turn it with ease. You say it loosened up some, do you think it would work for me, or is it still pretty firm? I do not have a lot of strength in my left arm and hand. I would be interested in what you have to say. If it is still rather stiff to turn, I might look at a different all wood model, which seem to turn quite easily. Thanks!

@Diane, Thank you so much, this does sound doable for me as I can use both hands, just not very strong on the left. I would do as you suggest and mostly leave it on a setting I use the most. I think I will get in touch with Pleasant Grain and order one. Thanks for your quick response. I do appreciate it.

Hi Lou, I just went over and turned it so I can give you my most recent experience. I use two hands to turn it and it works quite easily. There is slight resistant at each adjustment but with one hand on each side of the bowl It turns with no trouble.
I found a flour size I often use and leave it there. I use the finest setting for my bread flours and I love the texture of the sourdough bread I am getting. Even with whole wheat.
So I can recommend it for you if you can use both hands without pain and exert just a small amount of pressure to twist the bowl. And I do really enjoy this mill. It has never failed to give me the results I want with lots of different grains. I most often use wheat, rye and corn. Happy Baking!

That Arboblend is marketed as completely biodegradable doesn't mean what you may think it means. It is in no way the solution or even not part of the problem in terms of plastics in the environment.
This being said, no one is really even taking a swing at that problem so there is trivial added harm by your use of Arboblend. You won't see most of the consequences in your lifetime, anyhow. ;-)

Hi Chui, Thank you for bringing this up. I agree, Plastic harm in the environment affects all living things. I find it incredibly frustrating that we are continuing to ignore the problems caused by our unabated use of plastic and its consequences. I do think we are starting to see the impacts of this problem.
This komo mill is a compromise of sorts in this area. Pure wood mills tend to warp over time and that is the problem Arboblend was intended to solve. I really love this mill.
It works great. And since my last mill was 100% plastic I think this one is a step forward in reducing the plastic footprint. Not a complete solution but hopefully a move in the right direction. Happy Baking!

I would go to a dealer for the answers to these questions. I do own this mill but I have no idea how you can buy it in India. Try asking pleasant hill grains. This is their link in their website to this mill. https://pleasanthillgrain.com/komo-mio-grain-mill-flour-grinder-wood-stone-colors Best of luck!
