KoMo Mio

Whole grain breakfast breadCombine the freshest-ever look in grain mill design with impeccable grinding performance and what do you get? The iconic NEW KoMo Mio! Rarely has a grain mill introduction created excitement like the buzz for the Mio. One PHG newsletter reader responded immediately: "Are you kidding? Sign me up!" and their enthusiasm has been echoed by many. The striking cabinet of the KoMo Mio is solid European beechwood with trim made of Arboblend, an amazing new injection-moldable bioplastic. Made of wood lignin and cellulose fiber and sometimes referred to as liquid wood, Arboblend is attractive, lightweight and strong. Consisting of 100% renewable materials, it enables product designers to use wood in ways that were previously impossible. Arboblend's low cost has also allowed KoMo to make the Mio available at a price so low that, for a mill at this quality level, it's nearly as incredible as the Mio's revolutionary construction.

Inside the Mio's sharp exterior is an exceptionally advanced, yet admirably simple, milling mechanism. Precisely fitted corundum-ceramic burrs grind to any texture you choose, from exceedingly fine flour to coarse meal or cracked grain. All by simply rotating the grain mill's hopper to align with your choice on the front texture setting scale. The Mio is as natural in its approach as the materials it's made of and the grains it turns into nutritious, delicious, fresh whole grain flour.

Assorted whole grain breadsPower & capacity: All KoMo electric grain mills are equipped with specially developed motors that provide reliable and efficient power. The Mio, with its strong 400 watt motor produces 8-9 ounces of flour per minute for bread flour texture. Its large solid beechwood hopper holds 2 lb., 11 oz. of grain.

All dry grains can be ground with the KoMo Mio mill, including soft or hard wheat, oat groats (dehulled oats), rice, triticale, kamut, spelt, buckwheat, barley, rye, millet, teff, quinoa, amaranth, sorghum, soybeans and dent (field) corn. It will also grind lentils, dry beans (pinto, red, garbanzo/chickpeas, kidney & more), and dried, non-oily spices. It isn't suitable for herbs, oilseeds like flax or sesame, popcorn, or fibrous materials.

Dent (field) corn and soybeans can be ground to any texture from cracked to meal to very fine flour. For these very large-kerneled grains, grind first with the stones opened widely to produce cracked grain, then a second time if you want flour. The KoMo Mio will grind oats to a wonderfully soft, fine textured flour, but open the stones about five clicks (or so) wider than you would for a hard grain like wheat, otherwise the soft oat flour will fill the stones' furrows and in-feeding will stop. Opening the stones further will give you a cereal grind for porridge, or coarser yet for cracked oats, similar to steel-cut.

Easy to live with: As with all KoMo grinders, cleanup of the Mio is minimal and easy, and full access to the milling stones takes just seconds, without tools. A sealed lid keeps everything clean between uses. Sound level is a big issue with many grinders; being among the world's quietest-running grain mills, KoMo's products are kind to your ears and your nerves.

Rye seed breadA 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.

Choose from 110V or 230V models: The KoMo Mio grain mill is available in the standard 110V version for use on U.S. power, or a 230V version for use overseas. Mills with 230V power are equipped with a Euro plug. For more details about the Mio mill, click the specs tab above.

At Pleasant Hill Grain, our experience spans the milling spectrum from home-use to commercial. As the exclusive U.S. importer of Austrian-made KoMo mills, Pleasant Hill Grain is proud to represent their fine European craftsmanship to our customers. We'd be delighted to visit with you about a KoMo mill or any aspect of your milling needs. We'd appreciate your business, and we look forward to serving you in any way we can!

Whole Grain Nutrition: Harvest the Benefits!

Imagine that for years, your children ate mainly candy. Imagine that you did, too. Imagine an entire nation on a candy diet. Imagine the health consequences.

Whole grain pancakesNatural whole grains contain a myriad of health-essential nutrients, from proteins to vitamins and amino acids. But "white flour" consists only of the starchy endosperm of the wheat kernel. In its natural form the endosperm provides wholesome energy, but it's the least nutrient-rich part of the grain. Removed are the nutrient-packed bran, wheat germ, and wheat germ oil. Then to make it extra white, industrial processors go further, chemically bleaching it, and returning just enough of a few vitamins to stave off beriberi and rickets. They're allowed to call the end product "Enriched Flour" but a truthful label would read "Impoverished Flour." This snow white, denutritionalized substance is a commodity worth billions of dollars annually to its merchandisers because of a commercially useful characteristic: Unlimited shelf life. No matter how long it sits in the mass distribution channel, it can't go bad precisely because there's actually nothing left in it that can go bad. Nutritionally, it's bad when bagged. A few companies have grown enormously rich marketing this pseudo-food on the basis of convenience, ease, and its dazzling white appearance. But a blind eye was turned to the consequences of replacing real whole grain flour with something that looks special, yet is virtually devoid of nutrition. In essence, candy. So widely has this nutritional travesty become accepted that we call it—and think of it as—wheat flour. But to depart further from natural grain flour would scarcely be possible. Then to make matters worse, artificial sweeteners, flavors and colors, appetite stimulants and preservatives are added to many of our foods. "Artificial" tells you those things aren't naturally food. But have you ever wondered what they actually are, then? Did you know some of them are actually petroleum derivatives? What unintended side effects might those complex counterfeit compounds have on us? 

The human body is an absolute marvel; scientists have a long way to go to understand a tenth of how we work. But as capable and as resilient as our bodies are, common sense and history teach that we need wholesome, nutritious food to remain healthy and strong. The denatured byproducts being mass marketed today don't provide what we need, because they've been profoundly altered by processes in which real nutrition is considered last, or not at all.

Homemade artisan whole grain breadsThere's a great solution to this problem. By grinding grains in your kitchen and using the whole grain flour while it's fresh, you get the nutrition needed for strength and health. You also get far tastier food, with genuine character—incomparably more satisfying than today's mass marketed pretenders. After transitioning to whole grains, putting out a plate of white styro-bread will elicit comments like "Why are you giving us this... and where's the good stuff?". Even flour labeled as "whole grain" in stores falls far short of what you can easily grind yourself, because unless it's ground while you wait, the essential Vitamin E in true whole grain flour would go rancid in days (meaning that it's probably been removed), and all nutrients begin steadily oxidizing-away from exposure to oxygen as soon as grain is millled. What's in those bags is not whole grain flour if it's been sitting on a shelf for even a few days; that's literally impossible.

Making real food is more than doable, it's downright fun with help from Pleasant Hill Grain! A grain mill like the KoMo Classic is the place to start. And to make whole grain bread quickly, easily and with consistently wonderful results, nothing beats a quality stand mixer that's capable of mixing and kneading bread that's ready to pop in the oven — quickly and without hand kneading. These machines make it easy to turn the corner to a far better and more enjoyable way of eating!

  • Savings over KoMo Classic not worth it!
    By on - Verified Buyer
    My first experience with a grain mill was my brother's Komo Classic. Having a hard time swallowing the large price tag, I decided to go with the Mio instead. Due to quality control issues, I had to have a replacement sent for the first one. The second was in better shape but still had quality control issues. The truth is, the $150 savings is just not worth it. The Classic seems like it will last a lifetime... the Mio not so much. I returned my Mio and ordered a Classic instead and am SO HAPPY with my choice!

    Melissa, we're glad you love the KoMo Classic--we agree, it's awesome! And we'd also like to throw in this update: brand-new products like the Mio often have a little wrinkle or two to be ironed out, and the issue you experienced with the Mio has been resolved now. Thank you so much for your business, and for taking the time to send in the review!

  • New price, Previous Quality
    By on - Verified Buyer
    This mill is as quiet and grinds finely and as promised. I like not having to pay for the fancy woodwork of the original models. I previously had a classic Nutrimill and the Komo mio seems to fit my needs better at a now similar price. Thanks to all who have posted reviews in the past. The person I called to ask additional questions was extremely helpful as well. I’m told not to grind popcorn but I may void the warranty anyway just because I feel it will handle it without too much problem for the small quantities I do.

    We would strongly encourage you not to mill any popcorn. As with other stone burr mills, the risk with popcorn is not from eventual damage due to wear, but from a single kernel breaking a stone--because popcorn, while it is brittle, is also very hard, almost like glass. Thanks for your review, Roland.

  • KoMo Mio Grain Mill
    By on - Verified Buyer
    This grain mill seems to work quite well. I have two issues with it, though: it has a high-pitched squeal when grinding hard grains such as kamut (otherwise, it is just loud), and the flour is much warmer than I feel it should be.

    Jimmie, we suspect you're setting the stones too tightly together. We suggest backing the tension off just a little (by simply rotating the hopper counter-clockwise). Over-tightening of burrs does create excess heat. You should get flour that delivers ideal baking performance without any overheating or squealing, just by loosening things up a little. Thanks for your review!

  • High Quality
    By on - Verified Buyer
    I had only used the KitchenAid grinder attachment to mill grain before this, and its finest setting was still a ways from store-bought flour. This mill gives a very fine result, is straightforward and easy to use. I was wondering if the price difference from the "Classic" meant a lesser product, but I think it's just a bit smaller with some plastic trim. Very happy with the results.

    Just to clarify, while the trim on the Mio is, in a sense, "plastic", it's a wood-based material with polymer characteristics, not the petroleum-based material usually associated with the term. Thanks for your review Nathan!

  • Excellent, elegant flour mil
    By on - Verified Buyer
    Thanks to the whole team at KoMo. This is a solid mill that makes great flour. I got it for my wife's birthday so she can make the fresh, stone-ground sourdough she's always dreamed of. We're thrilled with it! We had an old Whisper Mill before this that finally gave out, and I'm honestly delighted at how technology has progressed. The Mio model is so affordable and still has everything we're looking for.

  • Even better than expected
    By on - Verified Buyer
    I previously was using my mom's old stone grinder from the 70s which grinds well but it's slow, super loud and very dusty. I went back and forth about which model to get and went with the Mio because of its tiny footprint on my baking counter. It is fast and no dust at all. Love it! I have used it for wheat, spelt and rye so far and I'm in love. It has taken my sourdough breads to another level!

  • Easy to use and quiet.
    By on - Verified Buyer
    This is a snap to adjust for fineness of grind and quiet to use. My previous mill (a high speed impact type) worked well but I needed hearing protection when I ran it. Not so with this mill. It’s about as loud as my stand mixer when grinding. The range of adjustment for fineness of grind is much wider than my previous mill. I have been able to grind from a coarse “grits-like” texture to fine flour. I believe it can grind more coarsely but I have not needed to do so yet. Finally, it is very attractive and fits easily on my countertop under my upper cabinets. It’s very convenient to leave it out and grind what I need just as I am ready to use it. I’m very happy with this mill so far.

  • Super competent mill and nice looking as well!

    Excellent mill! It is a huge improvement on the kitchen aid attachment I was previously using. Super fast and not too noisy.

  • Love this mill!
    By on - Verified Buyer
    This is our first experience of using a grain mill. I'd heard they were loud and messy but this one is no louder than the mixer on high and I only have to wipe down the machine and the counter it's sat on after using it. The kids (2 and 3 months) love watching the flour coming out the spout. We like the simple design (load at the top and flour at the bottom) and easy clean up. We use it for grinding hard winter wheat for bread and other baked goods like muffins and banana bread. The flour is perfect! The last load we sprouted and dehydrated before grinding - those were hands down the best muffins I've ever eaten!!!
