Modern countertop grain mills make it easy for anyone to grind fresh, flavorful flours. There are dozens of flour mills from which to choose. Fortunately, the search for an ideal mill can begin with three basic decisions — what power source to use, the appropriate milling mechanism and the maximum flour temperature to tolerate. Many mills are appropriate for family use as well as in a bootstrap business. The decision comes down to price, quality, versatility and convenience features.
Manual Mills. For the energetic, athletic, disciplined person, a manual mill (particularly the large flywheel type) can be a superb choice, with a low chance of nutrient-damaging heat buildup. But most manual mills require work, so be realistic — if there’s no flour, there can be no bread.
Electric Mills. If the primary objective is getting the flour ground and the bread on the table without any fuss, frills or fanfare, then an electric mill’s primary drawback — loss of use during power outages — may be acceptably rare. The zippiest, cleanest, easiest mills in this category are relatively inexpensive, and they do one heck of a job, then go back in the cupboard.
Convertible Mills. Many mill manufacturers have devised ways to make their mills convertible from manual to electric or vice versa, so grinding continues with or without power. It is important to select a convertible mill that works properly in either mode because some don’t.
Each grain mill has some mechanism for crushing, beating or grinding grain into meal, usually in a range of textures from coarse to fine. Some mechanisms are more versatile than others: They grind hard, soft, oily or wet items. Aside from the increasingly popular “oat roller,” two milling mechanisms dominate the home mill market: burr and impact.
Burr mills are the most common. They have two grinding plates, one fixed and the other rotated by a power source. The grain is fed into a gap between the burrs, which are grooved to aid the shearing and crushing of the grain. Composite stone burrs are constructed by pressing natural or artificial stones (and sometimes metal cutting blades) in a bed of cement. Metal burrs/plates, some of which are flat and some cone-shaped, are constructed of hardened cast steel or other metal. Basically, stone burrs tend to crush the grain, and metal burrs tend to break and shear it.
Impact mills employ two flat stainless steel heads with concentric rows of “teeth” that spin within each other at high speeds. Grain drops into the mechanism and is hammered, rather than ground, into flour. These very fast, efficient electric-only mills handle most dry, non-oily grains, but can only produce fine, not coarse, flours.
Heat is generated when grains are crushed between burrs or slammed around by metal pins. As milling time or speed increase, heat increases, which raises the risk of damage to nutrients and gluten. But when does heat buildup become a problem? Here’s what scientists either suspect or have documented:
112 to 115 degrees Fahrenheit. Heat-sensitive vitamins may begin to deteriorate, and the baking quality of gluten could be at risk of deterioration. This would be the upper limit for the super-safe miller.
122 degrees. Some enzymes are destroyed or become inactive, and some deterioration of gluten has been observed. (The baking performance of gluten declines progressively between 122 and 158 degrees with virtually all functionality lost by 167 degrees.)
More than 140 degrees. Losses in bread quality are clearly apparent; enzymes, heat-sensitive vitamins and probably many other healthful components are destroyed.

Readers’ Grain Mill Reviews
A Spiritual Practice
I purchased a Nutrimill grain mill in January 2003, and I love it. It can grind 4 cups of wheat into fine flour for bread making in about five minutes.
The mill fits on the kitchen counter, underneath the upper cabinets. It holds 20 cups of grain at a time, and its impact grinding mechanism is self-cleaning. Even though it’s marketed as being the quietest mill there is, it’s still pretty loud.
I buy my organic, high-protein wheat in 50-pound bags from the local Mennonite bulk food store at a very good price, and store it in recycled bakery icing buckets.
The actual bread-making process has become almost a spiritual practice for me, from grinding to kneading to slicing the finished breads. I listen to old-time music on my little kitchen radio, and the day’s problems literally melt away. We rarely eat meat, so we depend on our ‘staff of life’ to provide the protein missing in our diets. I substitute a half cup each of ground flax seed, wheat germ, soy flour and oat bran for 2 cups of the flour in the recipe, so I know the bread is super healthy. Our bread is so much cheaper to make than it would cost to buy a similar multi-grain one, and certainly cheaper than meat! The investment in the Nutrimill is paying off in money saved and improved health.
Toddler Loves Mom’s Bread
I started grinding my own flour in early 2003 after purchasing a Whisper Mill. I had been baking all of my family’s bread using store-bought whole-wheat flour. I knew that the nutritional quality had deteriorated in the purchased flours I was using.
The Whisper Mill has proven itself to be a great buy. I have ground both hard and soft wheat, buckwheat groats and soybeans. Our everyday bread is oatmeal/whole wheat. This is what I have fed my 4-year-old since he started eating bread. It is remarkable how sweet a loaf of bread made with freshly ground wheat tastes. My family continues to encourage my baking by showing their appreciation for my wholesome, homemade goodies with big smiles. And nothing makes me feel more satisfied than watching my 4-year-old bite into a big piece of buttered bread that I made myself. I know what he is putting into his mouth — something I would never know with purchased commercially produced bread products.
Maximum Nutritional Value
For about 25 years, my sole mill experience has been using a Bosch grain mill.
Although I may use it only a couple of times a month, at one point in time, I was making bread every week and needed to grind the grains. I have never had a moment’s problem with the mill. The set of earplugs is useful in blocking out the high-pitched motor sounds.
It is very satisfying to know I’m maximizing the nutritional value of the grain at mealtimes.
Trading Trout for Wheat
We live in Illinois, near St. Louis, and local wheat is not as rich in gluten as the hard, western red wheat. We camp out West regularly and bring back a few bushels of wheat every couple of years. Last time, on the way home after a fishing trip, I stopped at a grain elevator alongside of the railroad in western Colorado. The operator suggested his discharge chute would burst my plastic trash bags in which I had proposed to collect wheat from his elevator, so he directed me to Delmar Eichenberg, a local farmer. We visited Delmar, admired Native American artifacts he had collected, ended up trading fresh trout for a few bushels of his wheat, made a new friend and plan to repeat the visit soon.
I use a Vita-Mix to grind 2 cups at a time, which takes 1 1/2 minutes to turn wheat berries into fresh flour. I sometimes add dried cranberries, walnuts and raisins to the bread. We have five generations of our family here on the farm, and all enjoy it immensely. Warm, it’s irresistible; cold, it’s great with jelly, butter or plain; toasting even enhances the flavor. Ingredients are about 12 cents for a pound and a half loaf.

Evolution of The Loaf
It all started as a general interest in healthful eating. As vegetarians, bread is an important and exciting part of our diet. After our exposure to Zingerman’s bread (Ann Arbor, Mich.), we knew we would never find satisfaction with grocery store bread again. The excellent “chew” and hearty crust in these rustic, old-world and beautiful loaves is incomparable.
Several hundred hum-drum grocery loaves later, we began to put the pieces together:
1) The bread machine we got for Christmas one year,
2) The Laurel’s Kitchen Bread Book that lay dormantly on a shelf,
3) The availability of whole wheat berries just a short drive away at an Amish bulk food store,
4) The purchase of a hand-crank mill called “Our Very Best Grain Mill.”
Our plan was to make Desem (Day’-zum) bread once a week as outlined in Laurel’s book. Desem is Flemish for “starter”and is a unique way to bring wholesome wheat bread into your life. Desem deserves recognition because the ingredients are so pure and simple: wheat, water and salt. It was glorious and a memorable homesteading experience.
I refer to it as a memory now … because it only lasted about three weeks. Yes, we soon realized this hand-grinding plan was too time consuming. We exchanged the first mill for an electric model, The Grain Master Whisper Mill, with which we’ve been quite happy. It is fairly quiet (like a modest vacuum noise) and clean, but most importantly — it’s fast! It grinds in a few minutes what took 30 by hand.
Somewhere after the Grain Master purchase, our bread machine, which had become stationary on the kitchen countertop, broke down. Kneading the dough by hand was not an option due to the time and mess; after some research we bought a KitchenAid mixer. This machine saved even more time by cutting our kneading time down from 27 minutes in the bread machine to five.
So after quite a journey, we have our tools of choice: KitchenAid mixer and Grain Master Whisper Mill. These work well for our two-loaf-per-week Desem operation. We have not tired of this excellent loaf. Our process continues to evolve as does the quality of the bread, and our health with each week’s baking.
I urge you to reference these books in any article about whole-wheat bread, they have been incredibly helpful: The Laurel’s Kitchen Bread Book: A Guide to Whole-Grain Breadmaking, by Laurel Robertson, Carol Flinders, and Bronwen Godfrey. Also The Bread Builders: Hearth Loaves & Masonry Ovens by Daniel Wing and Alan Scott, 1999.
Mill That Does Everything
We have the most basic hand Corona mill. It’s a great little mill that grinds anything — corn, oats, acorns, sunflower seeds, flax. We have used some of the higher-quality, more pricey mills, and they do a better job creating fine flour, but they also plug when grinding oily seeds or soft grains like oats. For a first mill that does everything, we would recommend the Corona. Ours was about $50, it’s five years old, and we have never had a problem.
A Worthy Investment
I consider myself a junk food junkie and a health food nut all in one package. With such tendencies for food in these categories, I’m always looking for ways to balance my evil habits with providing healthy food for my family. A couple of years ago, we borrowed a small Corona mill. It ground nicely enough, but we had to pour the berries in at a snail’s pace — not practical for everyday use. We have been using a Diamant grain mill for a year and a half, and I am extremely pleased with it. True, it was a major financial investment — a basic model with all-purpose burrs costs $1,000. When we first got the mill, I had aspirations of “renting it out” to others to grind their own grain, but our lives have been busy so this never happened. It would be a great idea to own a mill in conjunction with others to offset the cost.
The Diamant is designed to be mounted to a table with four bolts, so it stays out all the time. If you don’t mind a 14-inch-high mill in the kitchen, this is a great model. I love looking at the mill on the counter. Its design is kind of old-fashioned with beautiful lines. I appreciate the fact that something designed for practical everyday use is lovely to look at. It is made of cast iron, so it should still be around for my great-grandchildren.
The Diamant mills easily. The more you tighten the burrs, the finer the flour, and the harder it is to turn. It mills easily, but does it mill fine? Yes! I am not sure if it can grind as fine as King Arthur whole-wheat flour, but I like mine a bit coarser. It also has a large-capacity hopper that can be full and still grind the grain effectively.
