Features to Consider for the Best Grain Mill for Home Brewing 

The best grain mill should allow you to crush and prepare your grains in a fast and effective manner.  Here are some of the features you should consider when choosing a grain mill for home brewing.

Product Number of Rollers Hopper Capacity (Pounds) Dimensions (Inches) Weight (Pounds)
MRbrew Malt Crusher2712.68 x 12.36 x 4.258.71
Northern Brewer Hullwrecker Grain Mill279 x 9 x 119.97
Farroday Stainless Steel Two Roller Malt Crusher27.714.92 x 12.83 x 4.417.7
Kegco KM11GM-3R Grain Mill37.714.2  12.2 x 9.2118.05

Number of Rollers 

Most grain mills for home brewing have two or three rollers. The 3 roller crusher like the Kegco KM11GM-3R Grain Mill operates by passing the grains between two gaps. The first one breaks the husk of the grain, and the second one grinds the grits. 

That means that a 3 roller mill will help protect the integrity of the grain’s husk, which will eventually help in the lautering process. On the other hand, 2 roller mills have one gap. That means you will have to adjust the gapping to achieve the right crushing balance between grits flour and husks.

Although 2 roller mills are not as fast as 3 roller mills, they still get the job done for most homebrewers. They are capable of crushing 5 to 10-gallon batches in several minutes. 

Roller Material 

Most grain crushers for homebrewing are made of stainless steel or hardened steel. Although hardened steel might be preferable due to its durability, it is not corrosive resistant like stainless steel. 

If you live in a coastal or damp region, it is advisable to go for a stainless steel mill such as the Farroday Stainless Steel Two Roller Malt Crusher. In most cases, the frame is constructed of an aluminum alloy, which helps to improve corrosion resistance and stability.

Hopper Size 

Hoppers are the funnel-shaped parts in a grain mill that holds the grains before they enter the mill. Usually, the size of the hopper is included in the specs of the mill. Hoppers vary in size depending on the model of the mill, and you need to choose a size that will meet your crushing requirements. 

For instance, the 7 pounds hopper capacity in the Northern Brewer Hullwrecker Grain Mill will allow you to work on the whole batch in one round. 

Mill Base

The base of a mill helps to catch the milled grain. Most grain mills for home brewing come with a wooden or metallic base. For instance, the Farroday Stainless Steel Two Roller Malt Crusher comes with a wooden base while the Northern Brewer Hullwrecker Grain Mill comes with a metal base. 

Keep in mind that some models such as the Kegco KM11GM-3R Grain Mill don’t come with a base and so you’ll need to check it out when purchasing. If the grain mill doesn’t come with a base, it means you need to purchase one separately, which translates to added costs.

Roller Gapping

Different homebrew systems use different grain crushes. Also, different grains have varying ideal crush sizes. Choosing a grain mill that will allow you to control your grain crush will help obtain the right crush sizes for your recipe and brewing system, allowing you to make consistent brews.

Although many grain mills come with an adjustable gap, you should pay attention to how accurate the adjustment is, and how easy it is to do it. Usually, it should feature markings to let you know the size that you have chosen, and a knob to help you adjust with ease. 

Also, pay attention to the adjustment range offered by the mill. Many grain mills such as the  MRbrew Malt Crusher offer a minimum adjustment of 0.025 inches to a maximum adjustment of 0.1 inches, which is sufficient for regular home brewing needs.

Drill-Powered or Hand-Powered

When purchasing a grain mill for home brewing, consider purchasing one that allows you to switch between milling with the drill attached or manual milling such as the MRbrew Malt Crusher. 

The drill-powered option will save you effort and time, and the hand-cranking option will help you when there is a power blackout.

Roller Crusher or Plate Crusher

There are two types of grain mills for home brewing; plate and roller mills. The plate mills crush the grains between plates and offer minimal control over the crushing. 

On the other hand, roller mills such as the Kegco KM11GM-3R Grain Mill crush grains between rollers, allowing you to have better control over the crush size. Keep in mind that the control you have over the crush size will have a direct impact on the quality of the beer produced. 

Frequently Asked Questions

How Do I Clean My Grain Mill?

Avoid using cleaning products or water to clean your grain mill. Rather, use a dry and clean paintbrush to dust off your mill. You can use compressed air to clean the tight corners and hard-to-reach places.

How Can I Power My Mill?

You can power the mill using a strong electric drill that features variable speed control. You will need an electric drill that can run slow at around 175 to 200 RPM to obtain the best crush.

For How Long Is Grain Good for Brewing After Milling?

You can’t tell whether the grain is still good for brewing by its smell and taste. If you keep the milled grain in a dry environment, it will remain good for 4 to 6 months after milling.

How Do I Know That a Grain Crush Is Good?

A grain crush is good if you have exposed the grain inside while preserving the integrity of the husk. You should not have whole uncrushed kernels or too much fine powder.

Do I Need to Mill Grain for Home Brewing?

You do not have to shred the grain into a fine powder unless you are utilizing a mash filtration system. In regular homebrewing, you will not be using this system and so you only need to invest in a malt mill that has a preset roller gap or adjustable rollers.

Conclusion 

You will need to invest in a grain Mill device if you want to improve your overall home brewing efficiency. Although choosing the best grain mill for home brewing can be challenging, you can’t go wrong with any option from the above mills.
