KoMo Duett Mill

A 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 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. At the same time this contact with water starts an enzymatic process which makes it easier for your metabolism to assimilate the minerals in the grain.

  • “Makes beautiful flours of all kinds of grains and beans. So happy... I would buy it again in a heart beat. You can't go wrong. ”

    – Sondra O., ME

Capacity 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 (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, 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.

The 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.

  • 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.

  • 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.

  • I would buy the KoMo Duett mill again and highly recommend it.

    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.
