When it comes to milling grains at home, having the right grain mill can make all the difference in the world. Home grain mills come in a variety of types, each with its own unique features and benefits. In this article, we’ll explore and compare the different types of home grain mills available, making it easier for you to choose the perfect one for your needs.

There are three primary types of grain mills—stone burr, impact, and steel burr—that you will find in the market today (I have a steel burr mill!). Each type offers specific advantages and can affect the quality of the flour and the milling process differently. Understanding these differences is essential to making an informed decision.

With this side-by-side comparison, I aim to provide you with all the information you need to make an informed decision about the type of grain mill that will be the most suitable for your kitchen, your baking, and your overall needs.

Electric vs. manual grain mills

Power source

When it comes to power source, electric grain mills obviously rely on electricity to operate. This can be more convenient in certain situations, especially if you want to process large quantities of grains quickly. On the other hand, manual grain mills, as the name suggests, don’t require electricity and rely on a hand-crank for operation. I find that manual mills are more suitable for smaller quantities and can be a good option if electricity isn’t readily available or you prefer the simplicity of a non-electric device.


In terms of speed, electric grain mills generally outpace their manual counterparts. They can process grains more quickly and efficiently, which can be a significant advantage in a busy kitchen. Manual grain mills, however, offer a slower and arguably more satisfying process, with the satisfaction of manually grinding your grains. For me, if time is of the essence, an electric mill is the way to go, but if I want a more hands-on experience, a manual mill is certainly worth considering.

Ease of use

Both electric and manual grain mills have their unique advantages in terms of ease of use. An electric mill simply requires the flick of a switch or the push of a button to begin grinding, making it a breeze to use. Manual mills, on the other hand, require more effort and physical input, as you’ll need to turn the crank to grind the grains. I appreciate the straightforward operation of electric mills, but there’s also something to be said for the tactile experience of a manual mill.


Finally, cost is a significant consideration when choosing between electric and manual grain mills. Electric mills are typically more expensive upfront but can process grains more quickly, which may, over time, offset their initial cost. Manual grain mills are generally more affordable but may take longer to process your grains. For me, the choice between an electric and a manual grain mill ultimately comes down to my budget and preferences, as both types have their own benefits.

Types of home grain mills

As an avid home baker and someone who enjoys experimenting with various grains, I have come across three main types of home grain mills: Stone Burr Mills, Steel Burr Mills, and Impact Mills. I will share my insights on each of these types, highlighting their key differences and features.

Stone burr sills

Stone burr mills are the most traditional and produce an exceptionally fine quality of flour. Mills use a pair of grinding stones made from a durable material, such as granite or a similar material, to slowly grind the grains into flour. This method ensures a consistent texture and preserves the nutritional value of the grain.

Stone burr mills are typically quieter than steel burr or impact mills, allowing for a more peaceful grinding experience. However, I did notice that they may be slower to grind the grains and often come at a higher price point due to their complex construction.

Some popular models include the KoMo Classic and KoMo Mio.

Steel burr mills

When it comes to a more affordable option, steel burr mills are worth considering. These mills use sharp-edged, hardened steel plates or discs to grind grains into flour. As a result, the grinding process is swift and efficient. However, steel burr mills tend to produce a slightly coarser flour compared to stone burr mills.

I find steel burr mills to be more versatile, as they can easily handle oily or high-moisture grains that may cause clogging issues in stone burr mills. They are sturdier and more reliable, making them an excellent choice for those on a budget or with limited space.

I own a Country Living Grain Mill, which is a steel burr mill.

Impact mills

Lastly, impact mills are an innovative and efficient option for home milling. These mills use a unique grinding mechanism that involves rotating metal fins moving at high speeds to pulverize grains. As the wheat passes through them, the high-impact process quickly breaks down the grain into flour.

One significant advantage I’ve noticed with impact mills is their ability to produce fine, uniform flour in a fraction of the time it takes stone burr or steel burr mills. However, they can be quite noisy during operation, which might be a concern for some users.

Key features to consider

Capacity and control

When choosing a home grain mill, it’s important to consider the mill’s capacity and control. The capacity refers to the amount of grain it can process at a time, which can vary depending on the size of the hopper. Control is essential in determining the quality and texture of the flour produced. I personally find that mills with adjustable grind settings offer more control over the final product, providing ease of use and allowing me to customize the flour’s texture.

Materials and durability

A mill’s materials and durability are crucial factors in its longevity and performance. Mills constructed with high-quality materials such as cast aluminum or stainless steel tend to last longer and ensure the integrity of nutrients in the flour. For example, the Country Living Mill (which I own) has a durable cast aluminum body, signifying its lasting construction. In my experience, it’s wise to invest in a well-built mill to avoid constant repairs or replacements.

Grinding mechanism

The grinding mechanism is at the core of a grain mill’s function. Home grain mills typically use one of three grinding mechanisms: stone burr, impact, or steel burr. Each type has its advantages and drawbacks. Stone burrs ensure a low heat production, preserving the grain’s nutrients and flavor. On the other hand, steel and impact burrs may generate more heat but offer greater versatility in milling various grains.


Versatility encompasses the mill’s ability to grind different types of grains and its compatibility with various power sources. Some mills can handle oily and wet grains as well as dry ones, expanding their range of use. In addition, some are designed for manual operation, while others can be electric or convertible from manual to electric. When selecting a mill, it’s useful to consider which features will suit my milling needs best.

Noise and size

Noise levels can be a concern when using a grain mill at home. Some models are significantly quieter than others, so it’s worth considering before making a purchase. Additionally, the mill’s size can impact its overall footprint and ease of storage. Smaller mills are ideal for limited space, while larger models may require a dedicated area.

Warranty and maintenance

The warranty and maintenance requirements of a grain mill are significant factors to consider when making a purchase. A good warranty policy offers peace of mind, ensuring that if any issues arise, they will be addressed by the manufacturer. Maintenance can vary between mills; some require minimal upkeep, while others need regular cleaning and servicing. It’s essential to find a balance between warranty coverage and manageable maintenance that suits my personal preferences and lifestyle.

Grains and other foods

In this section, I will discuss various types of foods that can be milled at home using a grain mill, including whole grains, legumes, seeds and nuts, and spices.

Whole grains

Whole grains are the foundation of home milling and provide the most versatility. With my grain mill, I can easily produce flour from a wide variety of grains like wheat, rye, oats, spelt, quinoa, millet, and barley. Each grain offers a unique flavor profile and nutritional benefit, allowing me to experiment with different flours in my baking and cooking.

Dry grains can be milled into various textures, from coarse to fine flour depending on the mill settings. For example, I can create:

  • Coarse flour – Perfect for rustic bread and cereals
  • Fine flour – Ideal for delicate pastries and cakes
  • Cracked grains – Great for warm cereal or adding texture to baked goods


Legumes, like nonoily beans and lentils, can also be milled at home. While these might not be as commonly used in baking as whole grains, they can add unique flavors and nutritional benefits to recipes. Protein-rich legume flours can be a great addition to gluten-free baking or for increasing the protein content of my baked goods.

Seeds and nuts

Grain mills can process many seeds and nuts, allowing me to create different types of flours and nut meals. Some common seeds and nuts that can be milled include:

  • Sunflower seeds
  • Flaxseeds
  • Sesame seeds
  • Almonds
  • Hazelnuts

Depending on the mill settings, I can create fine nut meals for delicate pastries or a coarser grind for things like nut-based crackers and crusts.


Dry spices like cinnamon sticks, cloves, and peppercorns can be difficult to mill, but by using a grain mill, I can create spices with the desired consistency. This allows me to have freshly ground spices with a more intense flavor and aroma than their pre-ground counterparts, which can elevate the flavors in my dishes.

The impact of freshly milled flour on baking

Flavor and shelf life

I’ve noticed that when baking with freshly milled flour, it adds so much more depth to the flavor of my baked goods. The taste is simply incomparable to store-bought flour. My fresh-ground flour gives a delightful, wholesome taste to breads, muffins, and pastries. Moreover, because the flour is freshly milled, the natural oils present in the grain haven’t had time to spoil, resulting in a longer shelf life for my flour.

Nutritional Value

I want the best possible nutrients for my family, and by using a home grain mill, I can ensure the flour I use retains its nutritional value. Unlike commercial flours, the milling process for freshly ground flour is rapid and preserves the bran and germ of the grain. This results in a final product that contains more vitamins and essential nutrients, promoting a healthier and more balanced diet.

Texture in baked goods

One aspect of baking with freshly milled flour that I had to adjust to was the difference in texture. My doughs now feel a bit grittier, which means I’ve had to modify recipes accordingly.
