Selecting the Best Grain/Flour Mill, Ultimate Buyers Guide

Over the years I have enjoyed using various grain mills (also known as wheat grinders) to grind different types of wheat berries into a fine or coarse flour. I have learned that some grain mills (grinders) are better in different circumstances depending on the type of flour wanted or other desired outcomes. I will help you know exactly which kind of wheat mill will work best for you in your individual circumstance.

To know if buying a grain/flour mill and storing wheat is worth it for you see if grinding your own flour is actually cheaper.

What is a Grain Mill (or Flour Grinder)?

A grain mill (or Flour grinder) is a grinder that can be used to grind wheat, oats, barley, corn, and other cereals into a fine powder or flour to use in baking and cooking. 

According to Wikipedia “A gristmill (also: grist mill, corn mill, flour mill, feed mill, or feedmill) grinds cereal grain into flour and middlings. The term can refer to either the grinding mechanism or the building that holds it. Grist is a grain that has been separated from its chaff in preparation for grinding.” 

A grain mill uses a few different mechanisms to grind or crush the grain into a wide range of textured flours. These mechanisms make it so that the mill can output fine or coarse flour, meal texture, cereal grind, or cracked grain.

When looking at grain/flour mills it is important to know how long the shelf life of flour is and how to store it in a way that prolongs its self-life. Check out our article What is the Shelf Life of Flour? 6 Commonly Used Flours.

5 Reasons Why You Need a Home Grain Mill (Flour Grinder)

1. Freshly ground flour has a much better flavor and produces better breads and pastries after baking than store-bought flour.
2. Buying specialty flours can be very expensive so having your own grain mill and a variety of grains to grind will save you a good amount of money, especially over time.
3. Fresh home ground flour has a much higher nutritional value. Store-bought flours use additives and bleaching to preserve the shelf life which strips out many of the nutrients in the flour.
4. Grinding or milling your own flour for baking will provide you with a strong feeling of peace, confidence, self-reliance, preparedness, and overall satisfaction.
5. Adding diversity and enjoyment to your diet by grinding a wide variety of wheat, grains, and more. You won’t be limited by the available flours that are for sale at Walmart or your local grocery store. You will have the power to decide what kind of flour you want in addition to how fine or coarse you want it for your baking.

Is it Cheaper to Grind Your Own Wheat?

Grinding your own wheat is cheaper than buying specialty flour for baking. The cost of a good electric grain mill will range between two and four hundred dollars but un-ground whole wheat/grains are mostly always cheaper than already ground whole wheat flour, especially specialty flours. Buying a good grain mill and wheat berries to grind your own flour will save you money over time as long as you use it.

What to Look for When Buying the Best Home Grain Mill (Ginder) for You

When looking to buy a grain mill you should consider the power source (manual or electric), type of milling mechanism, cost, ease of use, and nutritional value.    

5 things everyone should consider when looking for the right Home grain mill include:

• Power source (manual or electric) – Does an automatic (electric) or manual grain mill make the most sense for you? If you prioritize being able to grind wheat without electricity then a manual mill is right for you. If you prioritize a machine that is automatic and easier to use than an electric may be right for you. Maybe you’ll want one of both.
• Type of Mill/Grinder mechanism – If all you want to do is grind/mill common wheat into flour that you can bake with then an impact electric mill will work great for you (or a hand crank burr mill could work fine). However, if you want to produce your own cracked wheat, ultra fine flour, or cereal grind then a burr mill will likely fit your needs better.
• Cost – Electric Burr Mills often cost more than electric Impact Mills but offer more milling options and produce a higher quality flour. Likely the cheapest option will be a manual hand crank mill but your arm will likely tire quickly from cranking. Quality and convenience will increase the cost so it really depends on what you value most. 
• Nutritional value – Burr Mills (manual or electric) operate at a lower temperature therefore protect the nutritional integrity of the grain/wheat better than impact grinders.
• Ease of use & useability – Find a mill or grinder that is simple to use. If it is a hand crank make sure that it is simple to feed the hopper and convenient to crank. If it is electric make sure it can be plugged in and turned on easily, it should have an adjustable coarseness setting, and stores conveniently where you want.

Types of Grain Mills/Wheat Grinders

Two main types of mechanisms or burrs used in grain mills include:

1. Impact Grain Mills
2. Burr Grain Mills

1. Impact Grain Mills

Also known as “micronizers”. Probably the more popular type of grain mill because they are electric, easy to use, and quick. Impact mills feature a milling chamber with concentric rings of stainless steel fins. The fins, which never touch each other, spin at tens of thousands of revolutions per minute and burst grain kernels into small pieces as they’re impacted.

Features of Impact Grain Mills include:

• High speed performance 
• Moderate cost
• Above-average sound level
• Impact mills/grinders are electric-only
• Can produce flour in a range that is adjustable from coarse to a very fine flour
• Can mill/grind dry grains and beans

Negatives

• Cannot grind into a cereal texture, coarse cracked grain, or wet materials

Impact mills have become very popular since their introduction about thirty years ago. The market leaders in this category are the NutriMill Classic and the WonderMill.

While impact mills technically have steel burrs, generally they aren’t known as “steel burr mills”, a name that refers to slower-turning mills that crush the grain between rotating steel plates or cones (described below.)

2. Burr Grain Mills

The burrs are two plates, one on top of the other. One is fixed at the bottom, and the other rotates as the wheat berries are crushed and ground into flour in between the 2 plates.

The original burr mills used stone burr mechanisms to grind wheat berries but modern burr mill grinders can be made from:

• stone
• cast iron
• steel

Features of Stone Burr Grain Mills include:

• Quieter than impact grain mills
• Turn at slow RPMs
• Sizes vary from small to large
• Can produce a full range of texture flours including very fine flour, coarser flour, meal texture, cereal grind, and even cracked grain
• Cool-grinding to avoid exceeding 112 F (45 C) to protect the integrity of the flour
• Both electric and hand crank stone burr mills are available

Negatives

• Electric and hand crank stone burr grain mills generally cost more than impact mills/grinders

Features to Consider When Buying the Best Grain Mill for You

Differences between Burr and Impact mills/grinders

Here is a side-by-side comparison of burr and impact grinders to help you make a better decision as to which type of mill will better fit your needs.

Impact Grain Mills	Steel, Stone, & Cast Iron Burr Grain Mills
Cost Less	Cost More
Only Electric mills/grinders are available	Manual and/or electric mills/grinders are available
Cannot Grind oily/wet grains	Steel Burr – CAN grind oily wet grains Stone & Cast Iron Burr – CANNOT grind oily wet grains
Can produce fine-textured flour	Can produce ultra fine-textured flour & cracked grain
Mill gets warm and produces flour that has a temperature warm to the touch	Mill stays cool and produces flour that has a temperature cool to the touch
More Noisy	Less Noisy

Is a Grain Mill Worth it For You?

A Grain Mill is worth the cost for anyone who is interested in producing a higher than store-bought quality flour for baking, wants to have better-tasting breads, pastries, and grains, and desires to store grains for longer as to increase their own self-reliance. Honestly, I believe that a flour grinder is worth it for anyone who enjoys baking because freshly ground flour has a much higher nutritional value and tastes much better.
