Komo Mill Comparison Essay

Reviewing the new Mockmill 200 home mill

Let’s take a look at the Komo Fidibus 21 (Harvest 250) compared to the new Mockmill 200.


For clarity, I did purchase the Komo mill – but the Mockmill was graciously provided for comparison purposes. My goal is to be as impartial as possible in this review. 


Both of these mill designs are largely the designs of Wolfgang Mock (the Mo in Komo and the Mock in Mockmill). They are notably similar in design – though there are some obvious differences. 


Both of these mills are the closest in price – with the Komo Fidibus 21 priced at $399 USD and the Mockmill 200 at $349 USD. 


The Komo mill includes a 250 watt motor and 2.95” corundum-ceramic stones. It is housed in a nice beechwood cabinet. It is rated to mill ~150g of flour per minute. The mill includes a 12 year warranty.


The Mockmill 200 includes a 600 watt motor and 3.54” corundum-ceramic stones. It is housed in a liquid wood cabinet that seems a lot like a plastic housing. It is rated to mill -200g of flour per minute. It includes a 6 year warranty.


To get the closest equivalent Komo mill based on motor and stone sizes, you would need to purchase the Komo XL at $699 USD.

Wolfgang has clearly embarked on a quest to make home milling affordable. The new Mockmill 100 is currently priced at $259 USD. His goal may truly be to have a mill in every home. Why you should use fresh milled flours is another topic for another day. 


My thoughts on the mills outside of performance. 

There is no question that the cabinet of the Komo mill is much more solid feeling and I find it more aesthetically pleasing than that of the Mockmill. 


The Mockmill 200 shares a common cabinet and stone size with the Mockmill 100. The primary differences are the motors and possibly how the stones are dressed. The Mockmill 200 seems a little more solid than the 100 I have. This might be simply because of the extra couple pounds of weight or might be design changes between the preproduction and production models. I feel the need to note that the 200 mill I received had a cracked cabinet. This was clearly the result of shipping damage as the box was physically damaged. It does highlight, however, the slightly less rigid nature of the cabinet. 


Physical disassembly for cleaning is much simpler with the Komo mill. The hopper simply unscrews and the top stone lifts out to provide access to the milling chamber. To disassemble the Mockmill, you must first fully unscrew the adjustment lever. Pressing the tabs on the back of the hopper while lifting allows it to be removed. The top of the milling chamber is then unscrewed allowing the top stone to be removed. It is a lengthier disassembly and reassembly process.

The mill also needs to be “readjusted” after reassembling. 


Ease of adjustment from coarse to fine is also a little simpler with the Komo. You simply turn the hopper to make the adjustment. A wide range of adjustment is fully available. The Mockmill uses an adjustment lever which has a limited adjustment range. The range can be extended by loosening the lever (unscrewing slightly), moving the lever back to the other end of the range and retightening. It is relatively easy to do once you’ve done it a couple times. 


The mills are both adjusted for the finest flours at the point where the stones are just very lightly touching. 


oth mills have a couple common things worth noting. 

They both have small “loose” springs that apply upward pressure on the top stone. Be careful not to have them fall out and get lost. 

Both mills accumulate some amount of flour in the milling chamber. This can be several grams. The Komo seems to be slightly worse than the Mockmill. It is worth periodically cleaning the mills. 


I decided to choose a couple of grains that I thought might highlight the mills performance. I chose a heritage soft wheat and a Jasmine rice. 


Some basic observations:

The Komo is generally quieter while milling than the Mockmill. For the soft wheat, the Komo was 8db quieter at 88db vs 96db for the Mockmill. Both are loud. 


The flip side is how long you get to listen to the mill. The Mockmill delivered significantly faster milling times taking 1:30 to mill 300g of the soft wheat vs 4:15 for the Komo. 150g of rice took 0:39 vs 1:07. 


Flour temperatures with the faster milling times of the Mockmill were 7f cooler for the wheat and 2f for the rice. 


Let’s talk about the flour – the Mockmill 200 simply produces finer flours. Finer flours produce superior breads. Charts are included showing extraction rates for different sieve sizes. 

Notable is also milling corn. While the shallow grooves in the Komo stones make single pass milling impossible, the Mockmill makes fine corn flour is a single pass. (The Komo Classic is able to do the same).


If I was to summarize the categories that each would win:

  • Physical Appearance –  Komo
  • “Solidness” of cabinet – Komo
  • Adjusting Coarseness – Komo
  • Warranty – Komo
  • Noise Levels – Komo
  • Ease of Cleaning (Assy / DisAssy) – Komo

  • Price – Mockmill
  • Motor Power – Mockmill
  • Stone Size – Mockmill
  • Milling Speed – Mockmill
  • Flour Fineness – Mockmill
  • Flour Temp – Mockmill 


If I was to choose which categories are most critical – they would be price, milling speed, flour temperature and flour quality. In each of these critical areas, the Mockmill clearly outperforms the Komo. 


To Wolfgang I would say “well done”.

A fast affordable fully adjustable home stone mill that produces fine flours has finally arrived. It excels in every area that is truly important to the home miller. There just might be a new Sheriff in town. 


After trying to make the manual WonderMill Junior Deluxe grain mill work for me, I decided to switch to an electric grain mill.  After much research I purchased the KoMo Medium Electric Grain Mill from Pleasant Hill Grain. Despite having a ton of questions and speculation after my previous grain mill experience, I’ve been in love with this mill since day one. I’ve now had it nearly 2 years. Let me tell you more!

**I want to take a moment to state that I was not compensated for this review. I paid in full for my KoMo Mill. These words are all purely from my own experience. 

**For more information on wheat berries, including USA sources, see my post: East Coast Bulk Food Sources. Part One: Wheat Berries and Flour


Why I chose an electric grain mill:

I first owned a manual mill. After trying multiple ways to use that mill I concluded that the amount of time and effort a manual mill demands just did not fit my busy lifestyle with kids. I needed a hands-free, fast mill. I knew in choosing electric I would be giving up the ability to grind oily seeds/nuts but I found all those could be ground with my Ninja food processor and my coffee grinder. (If you’re wondering, wheat berries cannot be ground in a food processor…I tried :). You can read a thorough account of my experience with that manual mill by checking out my other post:  A Mom’s Honest Review Of The WonderMill Junior Hand Grain Mill.


Why I chose KoMo Mill: 

Durability and appearance. I didn’t want another plastic appliance for the kitchen. I’ve always felt that plastic both looks and acts cheap. However many (all?) competitive electric mills on the market have a mostly plastic exterior. The KoMo Mill with is crafted wooden housing looks like a work of art and looks beautiful on my counter. I don’t feel the need to hide it away like all my other appliances. Then durability…well it comes with a 12 year limited warranty which I find to be an amazing testament to KoMo’s faith in their product. I love when a company makes a product that they expect to last.


What impressed me about the Komo Mill:

Ah where to begin….short answer: everything.

Longer answer would be the satisfying of my initial concerns/questions:

  • quality of product
  • noise/how loud
  • consistency of ground grain
  • practicality for daily use.

Quality of product:

KoMo’s 12 year warranty had me hopeful from the start.  Upon arriving, the first thing I noticed was it’s heavy solid weight (about 15lbs). It stays put on my counter, no shaking, rattling, or moving (of the mill, my counter, or the contents in my cabinets underneath). The millstones are made of corundum and ceramic. To be honest, I don’t know much about materials, but the company claims this makes them more than rock hard which means minimal wear after years of use. The most I’ve ground at a time is 15lbs. I paused for a minute or two every 5 five minutes, for really no good reason. The mill was warm but kept on grinding with zero issues and no change in effort. I stopped at 15lbs because that was all I needed, not because I was worried about continuing. After two years of use I’ve yet to even scratch the hardwood exterior. I opened it up once just for curiosity of what the millstones looked like. In short, I’ve had no issues what so ever, the quality appears to be as awesome at the company claims.

Noise/How loud is the KoMo Mill:

I was dying to know this answer before purchase. I read so many reviews of competing companies and noise level was a hot topic. KoMo says 70dB when finely grinding hard Spelt grain but that still doesn’t give me an idea as I don’t often think of sounds in dB.  So just how loud is this mill? Well first let me clarify that when you first turn the mill on, BEFORE adding grain the mill is only a quiet hum, comparable to a microwave (mill MUST be running before grain is added!! and CANNOT be shut off until all grain in hopper is ground!!). I find it tolerable to be in the same room as this mill because it doesn’t have that obnoxious high pitched shrill sound of so many tools. There is a noticeable difference (dulling of pitch) when grinding with the lid on versus off. Everything below is the noise with grain actively being ground.

Can I hold a conversation standing next to the mill?  No…You can shout a word or two and probably be heard, but it will stop all conversations in the room. Step  about 6 feet away and you can talk loudly, or around the corner into another room and you can have a more normal conversation again.

Can I still hear my kids yelling and arguing?  Sorry, but yes. However you can still pretend you can’t hear them 😀

Food processor/blender? Quieter than my 1500 watt Ninja food processor/blender because it does not have the same obnoxious “shrillness” or electric motor “whine”. I find the KoMo mill much easier on my ears than my Ninja. If I’m using the Ninja for more than a few minutes, I put it in another room and shut the door. When I turn on the Ninja my kids cover their ears. With the KoMo they ask if I’m done but there’s no distress. The KoMo is still very loud, but I can be in the same room as it the whole time I’m grinding 10lbs of grain.

Coffee Grinder? Louder

Lawn mower? Quieter (and I don’t feel like I need ear protection)

Weed Eater? Quieter than a gas one but louder than an electric one…and certainly a low grinding sound and not the high pitch whine.

Kitchen Aid Mixer? Much louder

Vacuum cleaner? Little louder

WonderMill Junior Deluxe Manual Grain Mill? (what I owned before) Much louder (but minus the whole counter and all cabinet contents rattling).

Consistency of ground grain:

Love this aspect of the mill! I was very doubtful after my experience with a manual mill, but the KoMo mill doesn’t disappoint. First off you can adjust the grind from very fine to very coarse. You’re never going to have the complete silky smoothness of grocery store flour because fresh ground flour contains the whole seed including the germ (nutrient rich interior) and the bran (hard exterior). The result is that speckled appearance you see in the photos. Wheat germ and bran are removed from commercial white flour (along with any nutrients) so you have a silky feel. Fine grind with my KoMo Mill produces a nice soft flour. You’ll be able to feel a very fine texture to it when you rub it between your fingers, but nothing you would ever notice in baked goods. (*Fresh ground does bake differently than commercial and comes with some learning curves…future post topic for sure!)

Consistency? 100% absolutely! It’s all the same, no mix of a few bigger pieces. Whatever you set it at is what you get. If I grind a lot at one time, I will feel the flour after 5 lbs and might rotate the hopper one click finer before continuing. To me there is a slight increase in grain size as the stones warm up, but it’s all the flour, not sporadic bits like the manual mill I had.  I like that I can grind fine for baked items and then a few clicks coarser for breads. Then I can easily rotate the hopper to very coarse and slightly crush my oat groats for steel cut oats. I love being able to easily make small and large adjustments to the coarseness as I grind. Since the hopper moves with audible and easily felt “clicks” you can also remember what settings you like.

Practicality for daily use:

The only commercial flour I have bought since owning the KoMo Mill is self-rising flour (for these amazing 2-ingredient biscuits that are a must for holidays and rival those buttery KFC/Popeye’s buicuits!). Yes using fresh ground flour for all your baking needs from cookies to breads, does come with a learning curve and a difference in taste. That’s to be expected though, when going from compact, flavorless commercial flour, to fluffy nutrient filled fresh ground flour. So for me the positives far outweigh my frustration when a recipe doesn’t come out as I thought.

As I wanted, the KoMo Mill is fast and hands off. Once the wheat is poured into the hopper I only need to occasionally rotate the bowl catching the flour as it fills up. I can pour 2 lbs of wheat berries into the hopper and wait a few seconds before its low enough to set the lid on. 1lb hard red spring wheat berries took 2 minutes and 30 seconds to finely grind. There is no cloud of flour coating my kitchen either like I read in many reviews of other electric mills. I might notice a fine dust on the hood of my oven, but there’s no need to wipe down even the entire counter the mill is on. The mill grinds very efficiently and with little/no waste. One cup wheat berries finely ground, measured 14oz flour immediately after. By the next day this settled to 12oz. (With the manual mill I had, 1cup wheat berries = 10oz ground flour). I simply plug in, grind, un-plug. No clean up, no taking apart, super-duper easy. The only thing that stops me from using the mill at any point in any day is the noise (sleeping kids, holding a conversation, etc) but that would be the same case with a manual mill (in addition to physical labor).


General information about KoMo Mill that I love:

The KoMo Mill was intentionally designed to not need additional accessories and add-ons to operate. If you’ve read my review of my previous manual mill, then you know I bought additional accessories to try and make grinding easier. From day one with the KoMo Mill I have been able to plug in and go, I’ve never had to even think about buying something else for it.

The KoMo Mill was also intentionally designed to be user-accessible should they hear a strange noise and need to open it up. I’ve never had to do this, but did open it once out of curiosity to see the millstones. You simply continue to turn the hopper counter-clockwise and it lifts off. Then put it back on just as easily. No panic, warranty voiding, cursing, etc

What else can it grind?

My entire review has only referred to grinding wheat berries and spelt. I did try garbonzo beans once for a pancake recipe. It had a different grinding sound to it which was mildly unnerving, but it came out great, as did the pancakes. According to their distributor, Pleasant Hill Grain, the KoMo Mill grinds “soft or hard wheat, oat groats (dehulled oats), rice, triticale, kamut, spelt, buckwheat, barley, rye, millet, teff, quinoa, amaranth, sorghum and dent (field) corn. They will also grind lentils and dry beans (pinto, red, garbanzo, kidney & more).”


What discourages me about the KoMo Mill:

Alright, alright, if I HAVE to stretch and find a dislike it would be that I can’t grind popcorn in the mill for cornmeal. Popcorn is too hard and will void your warranty, so I don’t dare try! I knew this fact before I bought the mill and it didn’t deter me, and it would not stop me from recommending this mill to others. I was also unsuccessful at grinding popcorn in my manual mill.



I paid $460 for my KoMo Medium Electric Grain Mill when I bought it from Pleasant Hill Grains about 2 years ago. I’ve never regretted the purchase. The price tag felt like a lot, and was double that of my previous manual mill, but the ease of use and quality of ground flour, makes me feel that my money was well spent. I’m confident that this mill will last a long time. Should there be an issue, I have faith that as a company that takes such pride in their product, they would also stand by their product.

If you’re looking for an electric grain mill then I would highly recommend that you look into the KoMo Mill line. Pleasant Hill Grains was an easy and informative distributing company to work with, I see no reason why I wouldn’t reach out to them again if I had another purchase.
