My Overview & Opinion:

(Overview will be coming soon)


The Wonder Junior hand grain mill has a Double Clamp that holds very securely and easily to the end of a counter or table (2 inches thick or less) without damaging the surface. The clamp can also be removed so that you can bolt it to a surface.

We recommend using the double clamp system because it holds tight enough that the grain mill will not wobble (unlike most single clamp systems) and so you do not have to drill permanent holes in your counter. This double clamp is very beefy and wide, which makes even more secure than the Retsel Uni-Ark. There is nothing cheap about this double clamp mounting system.

The clamp knobs are spaced far enough apart that it is easy to tighten and loosen the clamp. The knobs also have nice grip with you whole hand and it doesn't hurt to turn and get it tight.

Milling Heads:

The Wonder Junior Deluxe Grain Mill comes with both stone milling heads and stainless steel burr heads so you can interchange them depending on your needs and preference. The stone burrs can produce supper fine pastry like flour or courser flour out of most any dry, non-oily grains. Stone burrs are easy and more efficient and easier to use than the stainless steal burrs when milling dry grains. The stone burrs have a metal backing to protect them from braking when dropped, shipped, or regular use. Most stone burrs used on hand mills to not have a metal backing and are can be fragile.

The stainless steal burrs are more versatile than stone mills but the do not mill flour quite as fine as stone mill. Stainless steal burrs will produce flour fine enough for almost all of your bread needs, just not supper fine flour. The major advantage of stainless steal burrs is that you can mill more than just dry grains. The stainless steal burrs allow you to also mill oily grains, nuts, seeds, coffee beans, soybeans, and more... You can even mill fresh peanuts into peanut butter.

Grain Hopper:

The Wonder Junior grain mill has a large 4 cup capacity hopper that is about 4 1/2 inches wide. This is slightly smaller capacity than the Country living grain mill but it is twice as big as the Retsel Uni-Ark grain mill. Being a bigger size means that you won't have to fill as often when milling larger quantities of grain. The hopper is wide enough that filling it is easy to do with out making a mess. The hopper is octagon shape which some say makes it easier to fill, I think it just makes it look more stylish. The Hopper is solid and part of the mill mold so you don't have to worry about it falling off when full of grain (unlike the Lehman, Family Grain Mill, and Back-To-Basics grain mills).

Mill Body:

This is a fairly attractive mill, in my opinion. Having said that, this mill does have some several dimples in the mold and the hopper hole above the auger is really rough (see photo in Additional Photos section below). This mill does come in several different colors to match your kitchen but, as far as I can tell, you have order by phone to get a different color.

The mold of this mill is made of Cast Aluminum making it very tough and secure. It also has a food grade powder coat to make easy to clean, more sanitary, and gives it a nice look.

What Can I Mill?:

With the 2 interchangable milling heads, stone heads and stainless steal burr heads, you can mill a large variety of things with the Wonder Junior Grain Mill. You can mill all small dry grains and dry beans. You can also mill nuts for nut butters, flax seeds or any other oily or wet grains or seeds, herbs and spices, soy beans, coffee beans and more... See list below for a more complete list (not all millable items are listed below, but it is a fairly good list of what the Wonder Junior Grain Mill can mill). WonderMill has also started a site called 'Will It Grind?' to show thing that you can grind with their grain mills.

NEW Wonder Junior Deluxe

The World's Best Hand Grain Mill

It's a big claim to call your product "The World's Best." But we know that after you have used the Wonder Junior hand grain mill that you will agree. For years hand grain mills have either been really cheap or really expensive. And unfortunately their ability to perform has been directly related to their cost. The cheap ones perform poorly and the expensive ones perform great. When we designed the Wonder Junior we set out to create the perfect storm in hand grain mills. We also wanted the versatility and high quality of the most expensive hand mills in a price range that was affordable to the homemaker. We found the perfect storm with the Wonder Junior hand grain mill.

What Elements Are Needed
to Create the Perfect Storm?

  1. High Quality and Reliability
    Although our mill is USA Designed and Patented, finding a mill manufacturer to produce it to our demanding standards was no easy task. Because of this reason we turned to the country that produces more mills and has more expertise in Milling than any other country in the World. That country is India. It is a historical fact that some of the Worlds finest mills and finest mill craftsmen are from India. We not only chose India but we chose the best manufacturer in India to produce our Wonder Junior hand mill. Along with the best manufacturing and design we also use the highest quality materials to insure that this grain mill will be around for generations of use.
  2. Versatility and Effectiveness
    Of the many hand grain mills on the market today there is no other hand mill that can perform all the tasks that the Wonder Junior hand mill can. Not only can the Wonder Junior hand mill perform more tasks but it does those tasks more effectively than all other mills. The Wondermil Junior hand mill can grind flour faster than any other hand mill. It can crack grains or produce pastry fine flour with one pass. It can grind spices, herbs, oily grains (like flax or coffee), and makes smooth and delicious nut butters (see for more info).
  3. Ease of use
    One of the most important requirements in a hand grain mill is that it is easy to set up and use- This was very important in our design. We didn't want separate plastic hoppers or lock pins and springs that can easily be lost or misplaced. Because of this we designed the sturdy one piece I Beam Uni-Body Mill, with the heavy duty bearings, solid steel shaft auger, and heavy double post clamp. The Wonder Junior is the easiest to use as well as the most rugged hand mill on the market. With the quick change head system you can switch from grinding dry grains, beans and legumes to oily grains, nuts and even coffee in just a couple of minutes. Nothing is more simple than the Wonder Junior Deluxe hand mill.

RAVE Reviews

Professionals of many backgrounds are beginning to see and rave about the quality and affordability of Wonder Junior. The Wonder Junior is especially getting plenty attention in the "prepping world".

  • Vickilynn Haycraft (owner of gave the Wonder Junior 5 out of 5 stars on the National Product Reviews Examiner ( See her full review.
  • Chef Brad (owner of, a leading authority on the many uses of grains, loves the versatility of the Wonder Junior. Watch his video.
  • Anitra Kerr (owner of, a best selling author and an international leader on living a healthy and organized lifestyle, favors the Wonder Junior as the hand grain mill of choice. Watch her video.
  • James Stevens (owner of, writer of the #1 selling Preparedness Guide "Making the Best of Basics" and host of the "Preparedness Radio Network" raves on his show (along with his guest Donna Miller of Miller Grain House) about how great the Wonder Junior is. Listen to the radio show.
  • David Sarti, a well known and un-traditional Prepper Enthusiast, was surprised to see it chew up pebbles during his torture testing of the Wonder Junior on his YouTube channel.
  • And the list goes on and on with those who love the Wonder Junior hand grain mill.

FASTER Than the
Country Living Grain Mill

With the NEW grain auger we implemented at the beginning of 2011, the Wonder Junior hand grain mill is much more aggressive at getting the job done fast. In a test performed at the WonderMill test kitchen, the Wonder Junior was able to grind 1 ¼ cups of flour in a single minute *80 turns* (see our video speed test). This is 65% (about 1/2 cup) more than we were able to produce with the Country Living grain mill with the same flour setting and the same amount of turns *80 turns*, and for half the price.

Than Other Hand Mills

Not only does the Wonder Junior Deluxe hand grain mill have a strong and secure table clamp that blows its competition away, but it now comes with a flour guide and cleaning brush to keep grinding mess to a minimum. This makes cleanup a breeze. This NEW flour guide effectively guides the flour to fall into you container, instead of all over your table.

Many expensive hand grain mills are quite heavy and large making them harder to set up, take down, and store. In fact many expensive hand mills require you to bolt them down, leaving holes in your table. This is not the case with the Wonder Junior. It weighs only 10 pounds, it is half the size of its expensive competitors, and comes with a sturdy and convenient table clamp to make using it convenient and simple.

The Wonder Junior can also be motorized to allow you to be creative and more efficient. A motorizing pulley or drill bit attachment is available from authorized dealers. Motorizing your Wonder Junior will void its warranty but it gives you more flexibility to do what you want.

Not only does the Wonder Junior Deluxe hand mill grind dry wheat and grains, it can grind many of the more oily grains and seeds. It can even mill spices, cloves, coffee beans, flax, and so on..... (go to to see more of what it can grind). And with its new aggressive grain auger, it can do nut butters better than hand any other hand grain mill on the Market.

Built TOUGHER than
Hand Mills in It's Price Range

We have already mentioned the superiority of the Wonder Junior Deluxe's table mount but its benefits do not end there. When compared to the competition in its price range, the Wonder Junior is thicker and wider in its body mold and it has no plastic parts. It's only non-metal parts are the nylon hand grips, clamp and adjustment knob, leaving it strong where it counts.

The Wonder Junior's stone burrs are not only thicker than the competitions' but it also has a metal backing to keep it from cracking in shipping, accidents, and every day use. You can be assured that this hand mill is built to give you a lifetime of use. The Wonder Junior hand grain mill also comes with a Limited Lifetime Warranty to put you mind at ease.

It's not Cheap,

The really cheap hand mills are usually a disappointment and fall far short of the mark of really performing any of their stated claims. Those slightly cheaper than the Wonder Junior Deluxe fall short of the quality, durability, versatility and the convenience that the Wonder Junior Deluxe offers. Buying a more expensive hand grain mill than the Wonder Junior Deluxe doesn't make any sense. Do you really want to pay two to three times as much for a more expensive hand mill that is not any more durable than the Wonder Junior or can accomplish what the Wonder Junior Deluxe can. The Wonder Junior Deluxe gives you everything you need and more.

The Answer is Simple

The Wonder Junior Deluxe hand grain mill is HANDS DOWN the Best hand grain mill you can buy for your money. (click here to find a dealer to purchase one)
