Whole grain starts to change once it is milled. That is the case for a home grain mill: you buy wheat berries or dried corn, grind what you need, and bake or cook the same day. It also gives you textures a bag does not, from cracked grain to fine flour.
The word covers very different machines, though. This guide compares seven, from an electric stone mill to a cast iron molino for corn, and says what each one can’t do. This is a Mexican kitchen’s site, so we paid close attention to corn and masa. Your choice comes down to what you grind, how much and whether you will crank by hand.

Quick verdict: which grain mill to buy
For most home bakers, the best grain mill is the NutriMill Harvest: a 450-watt electric stone mill that runs from pastry flour to cracked grain on one knob. For masa, nuts and power-free use, choose the WonderMill Junior Deluxe. If you own a KitchenAid mixer, start with the KitchenAid Grain Mill Attachment.
The table below compares five standout mills. All seven are reviewed in full after it, followed by how to choose and common questions.

Our picks for the best grain mill
1. NutriMill Harvest Electric Stone Grain Mill – Bread Flour Without the Cranking
For most home bakers, this is the mill that fits. It is a countertop electric stone mill with a 450-watt motor, and NutriMill’s listing says it mills all non-oily grains and legumes, from pastry flour down to cracked grain for cereal. A single texture knob sets the grind.
The stones are corundum, made in Germany, and the mill is designed and assembled in the United States. NutriMill lists a thermal auto-shutoff that protects the motor during long runs, and the mill is tested and listed by CSA. Lehman’s gives the hopper as 5 cups, which is a fair amount for a loaf or two.
The limit matters: stone mills and oily food do not mix. NutriMill says to keep oily and wet grains out of it, so this is a dry-flour machine and not a tool for peanuts, sesame or wet corn. For a tortilla kitchen, it will make dry cornmeal, but cooked nixtamal belongs in a different tool. If the mill stalls, NutriMill’s help pages say to turn the knob to its coarsest setting.
Why we like it
- 450-watt motor with thermal auto-shutoff, per the listing
- One knob runs from pastry flour to cracked grain
- German corundum stones
- Tested and listed by CSA
Key specifications
| Model | 789000 (Gold) |
|---|---|
| Power | Electric, 450 watts |
| Grinding parts | Corundum stones |
| Hopper | 5 cups (Lehman’s) |
| Grind range | Pastry flour to cracked grain |
| Mounting | Countertop |
| Made in | Stones from Germany; assembled in USA |

Why we recommend it
It suits anyone who bakes with whole grain every week and wants flour without clamping or cranking anything.
Skip it if you want to grind nuts, coffee, oily seeds or wet corn, which NutriMill says to keep out of it.
Pros and cons
Pros
- Quick, with no physical effort
- Wide range from one knob
- Sold in several colors
Cons
- Non-oily, dry foods only
- Needs an outlet and counter space
2. WonderMill Junior Deluxe Hand Grain Mill – Dry Flour and Masa From One Mill
This is the most versatile mill on the page, and the one that speaks to a Mexican kitchen. It comes with two sets of burrs. The stone burrs are for dry grain and beans, and the stainless steel burrs handle oily and higher-moisture food, including nuts, seeds and cocoa. WonderMill also includes a masa and nut butter auger, which it says makes masa for tortillas and tamales.
That combination covers what electric stone mills cannot. WonderMill says this hand mill takes on nuts, flax, sesame, coffee beans and dried coconut, all things its own electric mill can’t handle. The locking knob holds a setting from ultra-fine flour to super-coarse cracked grain.
The body is aircraft aluminum with an epoxy coating, and the double clamp fits a table or counter with no drilling. WonderMill says it grinds 1.25 cups of flour a minute, which is a maker’s figure and depends on the grain, the setting and your arm. Expect to work for a large batch. The listing does not state a hopper size or a warranty term, so check those before you buy.
Why we like it
- Stone and stainless steel burrs in one box
- Masa and nut butter auger included
- Locking grind knob
- Clamps on with no drilling
Key specifications
| Model | Junior Deluxe (70-WJDELUXE) |
|---|---|
| Power | Hand crank |
| Grinding parts | Stone and stainless steel burrs |
| Hopper | Not stated |
| Grind range | Ultra-fine flour to cracked grain |
| Mounting | Double clamp |
| Made in | Not stated |
| Warranty | Not stated |
Why we recommend it
It suits a cook who wants tamale masa one day and nut butter the next, or anyone who wants a mill that runs with no power.
Skip it if you bake several loaves a week and would rather not crank that much flour by hand.
Pros and cons
Pros
- Handles oily and moist food with the steel burrs
- Works without electricity
- Aluminum body, which the maker says is lighter than rivals
Cons
- Hand work on big batches
- Output figure is the maker’s own
- Hopper size and warranty term not stated in the listing
3. KitchenAid Grain Mill Attachment – A Mill You Store in a Drawer
If a KitchenAid stand mixer already sits on your counter, you may not need another machine. This all-metal attachment runs off the mixer’s motor, so the mill itself takes up little room. It takes low-moisture, non-oily grains such as wheat, corn, rye, oats, rice, barley, buckwheat and millet.
KitchenAid’s help pages set clear limits. Grind no more than the equivalent of 10 cups of flour on Speed 10 at a time, then let the mixer cool for at least 45 minutes. Oats, buckwheat and barley should be hulled first, and millet toasted. Coffee beans, sesame, peanuts, sunflower seeds and soybeans are out, because KitchenAid says high oil or moisture is a problem and coffee can damage the mechanism.
That cooling time is the real cost. It shows how hard milling works the motor, and that same mixer may have to knead the dough afterward. This is a tool for an occasional batch. This listing is model 5KGM and gives few details, so confirm the fit on your mixer before ordering. Our stand mixer guide covers the machines themselves.
Why we like it
- Uses the motor you already own
- All-metal construction, per the listing
- Stores in a drawer
- Fully adjustable grind
Key specifications
| Model | 5KGM |
|---|---|
| Power | From the stand mixer |
| Grinding parts | All metal; burr type not stated |
| Hopper | Not stated |
| Grind range | Fully adjustable |
| Mounting | Mixer attachment |
| Made in | Not stated |
| Warranty | Not stated |
Why we recommend it
It suits a KitchenAid owner who wants fresh flour now and then, and has no room for a dedicated mill.
Skip it if you plan to mill often or in bulk, because of the 45-minute cooling rule.
Pros and cons
Pros
- Smallest footprint here
- No second motor to buy
- Clear maker guidance on limits
Cons
- Needs a KitchenAid mixer
- Long cooling time after a full batch
- Sparse listing details
4. Lehman’s Manual Power Grain Mill – A Flywheel for Longer Sessions
Lehman’s, the Ohio retailer known for non-electric goods, sells this large mill under its own name. The feature that sets it apart is the 12-inch iron V-belt flywheel. Lehman’s says its momentum makes hand grinding easier. The same pulley means the mill can be motorized if you later want it to.
The burrs are stainless steel, electrolytically polished for a smooth surface. Lehman’s says the mill takes any free-flowing dry grain to pastry flour, naming wheat, corn, rye, rice, quinoa and small beans. The hopper holds 6 cups, the most of any hand mill here that states a size in cups.
This is a machine that stays put. It stands 14 inches high and has four pre-drilled holes for bolting to a base, so plan a bench or board for it. It is meant for free-flowing dry grain, and the listing does not state a warranty or where it is made. Ask the seller if either matters to you.
Why we like it
- 12-inch flywheel adds momentum
- 6-cup hopper
- Polished stainless steel burrs
- Can be motorized later
Key specifications
| Model | PLE-10A |
|---|---|
| Power | Hand crank; can be motorized |
| Grinding parts | Stainless steel burrs |
| Hopper | 6 cups |
| Grind range | Down to pastry flour |
| Mounting | Bolts down through four holes |
| Made in | Not stated |
| Warranty | Not stated |
Why we recommend it
It suits a home with room for a fixed mill, and a cook who wants real output with no power, whether by choice or for emergencies.
Skip it if you need a mill you can clamp on for an hour and put away in a cupboard.
Pros and cons
Pros
- Large hopper
- Option to add a motor
- Flywheel helps the crank
Cons
- Must be bolted down
- Large to place at 14 inches plus the flywheel
- Dry grain only
5. Victoria Manual Cast Iron Grain Mill, High Hopper – The Classic Molino for Corn
This is the classic clamp-on cast iron molino. Victoria says it has worked in its factories in Colombia since 1939, and its listing calls this a molino para moler maiz. The body is cast iron with double tin plating, and the grinding is done by white iron discs. An adjusting screw changes how coarse or fine the grind comes out.
Be clear about what it is. Victoria states that this mill cannot reach a superfine texture and will not grind whole wheat into a fine powder. If you want bread flour, buy another mill on this page. If you want cracked corn, coarse grinds of spices, coffee or home-brewing grain, this is a simple tool for the job.
It clamps to a table top from 1/2 to 2 inches thick, with a rubber pad to protect the surface. The size listed for this high hopper version is 2,400 grams. For a guide to the corn itself, see our page on the best corn for masa harina, and our explainer on nixtamalization covers why cooked corn behaves differently from dry.
Why we like it
- Cast iron with double tin plating
- White iron discs
- Clamps to tops 1/2 to 2 inches thick
- Honest listing about its limits
Key specifications
| Model | GRN-100 |
|---|---|
| Power | Hand crank |
| Grinding parts | White iron discs |
| Hopper | High hopper, 2,400 g |
| Grind range | Coarse; not superfine |
| Mounting | Table clamp |
| Made in | Colombia |
| Warranty | 90 days limited |
Why we recommend it
It suits a cook who grinds corn and coarse grains, and values a simple cast iron tool over fine flour.
Skip it if you want fine wheat flour, because Victoria says plainly that it will not make it.
Pros and cons
Pros
- Simple design with an adjusting screw
- Listing covers corn, coffee, spices and nuts
- Long-running maker
Cons
- No fine flour
- Clamp mounting only
- Only a 90-day limited warranty
6. Kitchen Crop The Grain Mill – Small, Light and Clamp-On
Kitchen Crop’s small hand mill is the entry point on this page. It weighs less than 3 pounds, holds 2 cups in the hopper and clamps to a counter or table up to 2 inches thick. That makes it easy to pull out of a cupboard for a single batch of pancakes or a small loaf.
It uses stainless steel burrs for wheat, rice, oats, barley, rye, corn, beans, peppercorns and non-oily seeds. An adjustment dial runs from coarse cracked grain to fine, bread-quality flour. If you tire of cranking, an optional electric drive motor is sold separately.
Its 5-year warranty is long for a small hand tool. Expect to refill the 2-cup hopper often, and keep it away from oily food, which the listing excludes. A light mill also depends on a firm clamp, so check the counter edge before you buy: a thick stone overhang can rule it out.
Why we like it
- Under 3 pounds
- Stainless steel burrs
- Accepts an optional motor
- 5-year warranty
Key specifications
| Model | VKP1248 |
|---|---|
| Power | Hand crank; motor sold separately |
| Grinding parts | Stainless steel burrs |
| Hopper | 2 cups |
| Grind range | Cracked grain to bread flour |
| Mounting | Clamp, up to 2 inches |
| Made in | Not stated |
| Warranty | 5 years |
Why we recommend it
It suits a small household trying fresh flour for the first time, or anyone with little storage.
Skip it if you bake in quantity, since the 2-cup hopper needs regular refills.
Pros and cons
Pros
- Easy to store
- Upgrade path to a motor
- Long warranty for its size
Cons
- Small hopper
- Non-oily food only
- Hand work unless you add a motor
7. Corona Manual Grain Mill, Low Hopper – A Molino for Masa and More
Corona’s hand mill is a cast iron molino made in Colombia, and the listing is written for the food this site cares about: it names masa, tortillas, tamales and arepas, along with flour, cracked grains, spices, coffee beans and dried peppers. Food-contact parts have food-safe tin plating, according to the listing.
The listing gives a 0.8-quart hopper and grinding plates that adjust from coarse to fine. A clamp grips a counter up to 1.45 inches thick, with a stabilizing pad, and the kit comes with the hopper, plates, clamp, handle and mounting hardware. It is smaller than the Victoria’s high hopper, so expect to refill it more often.
It is hand-clean only, and the listing does not state a warranty. Treat the fine end of the range as the maker’s claim: we have not used it, and a plate mill is not the same job as a stone mill making bread flour.
Why we like it
- Listing names masa, tortillas and tamales
- Adjusts from coarse to fine, per the listing
- Food-safe tin plating, per the listing
- Clamps to a counter edge
Key specifications
| Model | L10800 |
|---|---|
| Power | Hand crank |
| Grinding parts | Grinding plates, tin-plated cast iron |
| Hopper | 0.8 quart |
| Grind range | Coarse to fine, per the listing |
| Mounting | Clamp, counters up to 1.45 in |
| Made in | Colombia |
| Warranty | Not stated |
Why we recommend it
It suits a cook who wants a smaller hand molino for corn, masa and dried chiles, with a counter edge to clamp it to.
Skip it if you bake bread every week; a hand mill is slow work, and the NutriMill Harvest is the better fit.
Pros and cons
Pros
- Written for corn and masa
- Needs no power
- Complete kit in the box
Cons
- Hand crank only
- Clamp limits counter choice
- Warranty not stated
Stones, burrs or iron plates: how the mills differ
The grinding parts decide what a mill can take.
- Stones. Corundum and other mineral stones make flour from dry grain. NutriMill keeps oily and wet food away from its stones, and WonderMill reserves its stone burrs for dry grain.
- Steel burrs. These handle dry grain and, on some mills such as the WonderMill, oily and moist food too. Check the listing before you try it: Kitchen Crop’s steel burrs are for non-oily food only.
- Iron discs. The Victoria uses them for coarser work. They suit corn and do not aim for fine flour. The Corona uses tin-plated grinding plates, which its listing says go from coarse to fine.
How to choose a grain mill for home use
- What you grind. Make a list first. Wheat for bread points to stones. Corn for masa, nuts or coffee points to a mill with steel burrs or an auger.
- How often. A weekly baker will want an electric mill. A monthly batch is fine by hand or on a mixer.
- Fineness. Pastry flour and cracked corn are very different jobs. Don’t assume a mill can do both. Victoria says its mill won’t reach superfine.
- Mounting. A clamp needs a counter edge it can grip, and a bolted mill needs a bench. Measure before you buy.
- Warranty and parts. The stated terms here run from 90 days to five years, and several listings don’t say. Ask about replacement burrs too.
- Storing the flour. Milling more than you need gives away the point of milling. Washington State University Extension says whole-wheat flour keeps only 1 to 3 months at room temperature because the oils in the germ turn rancid, and gives longer times for the refrigerator and freezer. A sealed flour container helps.
How we picked these seven mills
We have not used these products ourselves. We went through the grain mills sold on Amazon in the United States, kept only items in stock when we checked, and read each maker’s listing plus maker guidance from KitchenAid and NutriMill. Lehman’s product page supplied the Harvest’s hopper size.
We could not find a rigorous independent test of these mills to cite, so treat the claims here as the makers’ own. We were strict because these tools touch food. We kept to established makers that state their materials, and left out the many unbranded mixer attachments and high-speed blade pulverizers, which are not what this page means by a mill. Four familiar names are missing for stock reasons: Mockmill and KoMo mills were not available on Amazon when we checked, and the Country Living and The Kitchen Mill listings showed limited stock. The NutriMill Impact high-speed mill was out of stock when we last checked. We searched the recall database of the U.S. Consumer Product Safety Commission by brand and found no recall of a grain mill from these makers.
Grain mill questions, answered
What is the best grain mill for home use?
For regular bread baking, the NutriMill Harvest. For a mill that needs no power and handles masa and nuts, the WonderMill Junior Deluxe.
Can a grain mill make masa for tortillas?
Dry mills make corn flour or cornmeal, which is not the same as masa from nixtamalized corn. WonderMill includes a masa auger for this job. For most home cooks, masa harina is still the simple route, and our tortilla press guide takes it from there.
Is a hand mill or an electric mill better?
Electric mills are quicker and easier for regular baking. Hand mills work with no power, and some take food that electric stone mills can’t. Your batch size usually decides it.
Can I grind coffee or nuts in a grain mill?
Only in some. KitchenAid and NutriMill say to keep oily foods out. WonderMill’s hand mill takes them with its steel burrs, and Victoria’s listing includes coffee and nuts.
Does the KitchenAid attachment strain the mixer?
KitchenAid sets limits for it: no more than the equivalent of 10 cups of flour on Speed 10, then at least 45 minutes of cooling.
How should I store fresh flour?
Mill what you need, and keep any extra airtight in the refrigerator or freezer, as WSU Extension advises. Let cold flour come to room temperature before making a yeast dough.
Our final pick for fresh flour
Buy the NutriMill Harvest for regular bread flour. Choose the WonderMill for masa and oily foods, the KitchenAid attachment if you own the mixer, the Lehman’s for big hand batches, the Victoria for corn, the Kitchen Crop for small kitchens and the Corona for a smaller molino.
For the baking itself, see the best bread machine and our note on corn vs flour tortillas. And if you would rather leave the tortillas to us, see the menu or call to order.
