KoMo Duett

Whole grain sourdough bouleA perfect all-around grain milling solution, the KoMo Duett provides both freshly ground flour and flaked grains. Its beautiful cabinet, constructed of solid beechwood and furniture grade beech veneer, contains separate motors that allow you to grind and flake simultaneously or independently. Included with the KoMo Duett is a handmade ceramic bowl with a cool, smooth surface that complements the mill's warm finish.

The Austrian-made KoMo Duett lets you start the day with delicious fresh flakes in the morning, make fine flour at midday for an afternoon cake, and crush poppy seeds for both. It's offered in a choice of models, the Duett 100 and the Duett 200. The two share the same flaker, but on the grinder side the 200 model features an extra large motor for high speed flour output. The cabinets and hoppers of the two models are identical.

Oats are a naturally soft grain and more of our customers roll oats than any other grain in their Duett—but many other grains including wheat, rye, barley and millet can be flaked too, with a little preparation. These grains are normally dry and hard. To soften them, hold them under running water briefly in a strainer. Then spread the grains on a cloth or towel to let them dry over night or for at least 3-4 hours. This time will vary depending on the grain used, but a little experimentation will help optimize the process. The softened grain will flatten nicely into flakes, similar to commercially available rolled oats. Contact with water also starts an enzymatic process that makes it easier for your metabolism to assimilate the minerals in the grain.

  • “The service was excellent. The mill arrived very promptly and I received patient, kind help to learn how to operate it.”

    – Barbara T., IN

whole grain nut seed breadCapacity of the grinder hopper is 2 lb., 10 oz. The 360 watt motor of the Duett 100 produces 8-9 ounces per minute for bread flour texture, while the 600 watt motor of the Duett 200 turns out 10-11 ounces per minute. Both grinders have precisely fitted corundum-ceramic burrs and are adjustable to grind to any texture you choose, from exceedingly fine flour to coarse meal (or just cracked if you wish). All by simply rotating the hopper to align with your choice on the front texture setting scale. The flaker has a 6.4 oz. hopper and its 140 watt motor flakes 2.8 to 3.5 oz. of oats per minute. Flake thickness is adjustable from .3mm to .65mm. 

If you want the full range of capability from grinder to flaker, the KoMo Duett offers significant savings compared to buying a mill and a flaker separately. The grinder side will grind hard or soft wheat, oat groats (dehulled oats), rice, triticale, kamut, spelt, buckwheat, barley, rye, millet, teff, quinoa, amaranth, sorghum 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 Duett 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.

  • “Every once in a while we come across an Internet shop that sets new standards for dependability and excellence of service. I’ve learned if you sell it, then it's the best value anywhere.”

    – Ben Reisz, Kuwait

Fresh oatmeal with flaked oatsThe Duett's flaker is perfect for rolling all softer grains like oat groats. As with all KoMo grinders, cleanup is minimal and easy and access to the milling chamber takes just a moment and requires no tools.

Choose from 110V or 230V models: The Duett 100 mill is available in the standard 110V version for use with U.S. electrical power, or a 230V version for use overseas. The 230V mills are equipped with a Euro plug. Selecting a model and clicking the specs tab will show more details about Duett mills.

If you prepare food for someone with a food allergy, see KoMo's optional interchangeable insert system. This ingenious solution lets you grind different types of grain in the same mill while keeping food types completely separate.

Pleasant Hill Grain carries a wide range of whole grain products, including oat groats.

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!

KoMo Protects and Restores Forests

  • I would buy the KoMo Duett mill again and highly recommend it.
    By on
    I researched grain mills for months and agonized over this purchase because of the price. It is my first and hopefully the last mill I’ll ever need. I’ve had this mill for about a year and have no regrets. It does an excellent job of milling grains and flaking oats. I love that both functions offer a wide range of fine to coarse settings. Besides the high quality craftsmanship the other big selling feature to me is that it is so attractive that I don’t have to store it & pull it out every time I want to use it and I know this has led me to use it more frequently. Cleaning it is also very easy. The only problem I ran into was the top magnet holding the wooden front of the flaker came loose recently when I removed it to adjust the coarseness setting & the magnet would fall right into the flaker. Luckily the machine was always off when this happened. I tried to glue it back in, but that didn’t work because I think the magnet was so strong. The easy fix was to screw a thin metal faceplate across and over the top of the magnet.

  • Komo Duett 200: It Does
    By on - Verified Buyer
    I expected that the KoMo Duett would grind our wheat berries well, and it does. I expected it to flake the oat groats well, and it does. The grind is easily adjustable from coarsely cracked to fine flour. It's fast, and not terribly noisy (though not quiet). What really pleases me is that we no longer have to have a bin of flour for my bread making or a bag of oatmeal for baking or breakfast. Bins of different wheat berries and oat groats will last much longer and keep our kitchen much tidier. I can mix my hard red wheat berries and the hard white right into the hopper. Out of the Duett comes my bread flour. Our flour and oat meal will be fresher. An added benefit is that the Duett is a very handsome appliance, and cleanup after operation is minimal.

  • Great, Easy to Use and Flexible Grain Mill
    By on - Verified Buyer
    I bought this mill to replace a 42 year old, yes that's how long I've been grinding my own flours, Marathon Uni-Mill! I dithered and stalled for months before I finally made this purchase. I only wish I had opted to do it sooner!! My old mill was locked into one setting and was on the verge of dying a slow death so I finally gave in and bought the KoMo Duett and have been having a great time grinding things I had not been able to grind for many years, i.e. , wheat, rice, garbanzo, rye, barley and bean flours to make all kinds of things. Love the multiple settings on the mill allowing such flexibility to grind big beans on one setting and put back through on a finer setting. Makes beautiful flours of all kinds of grains and beans. So happy I made the purchase. I would buy it again in a heart beat. You can't go wrong.

  • KoMo Duett 200 works great!
    By on - Verified Buyer
    I am only beginning to explore freshly milled and flaked grains, but I can tell already they are much better than store bought flour and oatmeal. My bread, oatmeal and granola somehow feel more nourishing. This is my first mill and flaker but they have been very easy to use and are quite attractive on my counter. I was concerned that it might create a lot of dust, but that has not happened. Only a little from the flaker right around the bowl. The mill seems pretty loud, although I have nothing to compare it with. I just wear earplugs.

  • KoMo Duett Long term review: Attractive, functional, and economical
    By on - Verified Buyer
    After owning a KoMo Duett 100 mill, purchased from PHG, for five years, I thought it was time to write a review. The Duett 100 has been a wonderful addition to our kitchen. We have milled over 500 lbs of grain and flaked several hundreds pounds of oats and other grains. The mill performs flawlessly each and every time. As the millstones have begun to wear slightly it has become possible to mill flour finer than the when the mill was purchased. We use the mill for making "stone ground" texture flour, cornmeal, and the like, as well as very fine flour (that we sometimes sift) for sourdough, commercial yeast, and chemically leavened breads. We also use it for milling soybeans, chickpeas, and similar foodstuffs. The only tiny imperfection in the unit's design is the thickness adjustment on the flaker, which tends to get stuck in the "fein" (thin) position, and requires a pair of pliers to loosen. Even after 5 years, the attractive wood cabinetry of the unit garners compliments from visitors. I expect to get many decades of use out of this unit, and consider it to be an excellent buy.

  • Wonderful Flaker and Mill
    By on - Verified Buyer
    We love our mill. It allows us to be gluten free at a much lower cost. We use the flaker the most, pretty much daily. The mill is great to use with several drier grains. We even use a mix of 2:1 rice to oat goats in it and the flour is great.

  • Best Rolled Oats
    By on - Verified Buyer
    Actions speak louder than words: Every weekday morning I put 1/2 cup of oats in my KoMo Duett 100 and roll them for a delicious breakfast with dried blueberries and milk. Best rolled oats.

  • Love the Dual Purpose of the KoMo Duett Flaker and Mill
    By on - Verified Buyer
    I have been using a KoMo Classic for milling hard and soft wheat berries for about a year. My wife purchased the KoMo FlicFloc Oat/Grain Flaker as a gift to roll oat groats. We quickly realized that flaking oats almost daily (family of 5) was becoming a chore. My family LOVES the flavor of freshly rolled oats. We decided to purchase the KoMo Duett Flaker and Mill and could not be more satisfied. My 80 year old mom can now roll her own oats in the powered flaker. I also upgraded to the Duett 200 model with the 600 w-3/4 HP motor. I bake 3-4 loaves of bread weekly and put about 3200 grams of berries a week through the mill. I do see a notable difference in milling time with the upgrade in motor. I purchased the KoMo Flour sifter accessory and use that now on my KoMo Classic.

    Great service from Pleasant Hill Grain. Great product from KoMo. Worth the purchase if you have the need to mill and flake. You won't be disappointed.
