Oat Rollers Are NOT Grain Mills

I have seen oat rollers advertised as grain mills by many dealers and websites but this is something they are not good for, if they can even do it at all. I have used many oat rollers and have tried to make wheat flour with them and it only makes a chunky flour (or coarse meal) that is at best 'cream of wheat' texture after running it through 2 or 3 times, I would never use this flour for bread. The only thing I have seen an oat roller make flour out of is dry beans, only a few of the oat rollers can do this. I would like to address the 2 most popular oat rollers that are sometimes advertised as a grain mill, the Marga and the Norpro grain rollers.

Marga Mulino Oat Roller

The Marga Mulino, made in Italy, is so nice for making rolled oats and flaked grains but when it comes to making grain flour it is much less than desirable. It really takes 3 runs through the roller to get anything that resembles whole wheat flour (see photos A, B, and C below) and even then the cheap-o Back-to-Basics hand grain mill makes flour that is much finer the first pass through it. If you buy a this oat roller hoping to double it as a grain mill your in for a great disappointment.

I also tried other dry items like beans and corn and the results were also a course meal instead of flour. These larger items also do not feed through the rollers that well and sometimes need some coaksing. The popcorn I put through these rollers was very choppy and made the chunkiest corn meal I have ever seen, don't know if I would even use it.

Marga Mulino Flour Test Results:

I compared the whole wheat flour from the Marga to the whole wheat flour produced by a quality hand grain mill (like the Wonder Junior, Country Living, or Grain Maker).

As you can see the flour produced by the Marga Mulino is very coarse, even after 3 times through, when compared to a quaility hand or electric grain mill.

Norpro Grain Grinder

This is a China copy of the Marga Mulino and feels cheap in comparison. When it comes to performance, the Norpro is very much laking when compared to the Marga Oat Roller. This is the oat roller that most often gets falsely advertised as a grain mill. The first time I ran whole wheat through the Norpro, it came out coarser than the Marga Mulino did. After running it through 3 times the flour was the same as the Marga's flour on the 3rd time through. If you buy a this oat roller hoping to double it as a grain mill you are again in for a great disappointment. It comes with a so-called flour sifter but the holes in this flour sifter are so big that it lets most of the chunks through.

When I tried beans and corn in Norpro they would not even feed through the rollers. This was very disappointing because they they advertise on their box that it can: "Grind wheat, rye, barley, buckwheat, corn, rice, millet, soy, beans, peas, alfalfa and any other dry seed or legume". I would say that the Norpro can not grind any hard grain, bean, or corn that is larger than whole oats. I think that the Marga oat roller has better rollers that grip the items going through where the Norpro grain grinder just doesn't grip it.

Great for Oat Rolling & Grain Flaking

Though these 2 Oat rollers do not make very usable flour, they still are good for what they were made for: Producing Rolled Oats and Flaked Grains. I have also found them nice for making cracked grains. If you have the money, I would recommend that you buy the Marga over the Norpro, it performs better and will last longer.


I want to order a Molino Marga oat rollers (Marcato Getreidemühle Marga)
Ülease give me an adress for ordering.
ance i got this molino over Amazon\Germany but they don´t have it now.
best regards Hans Ittlinger

I use the margaa mill for crushing barley malt for brewing purposes an it performs great.

Thank you for this review. It is exactly what I needed to know! I need to roll oats for my family and for the animals.
