From the Tools chapter · Grain Mills
You already know that I think milling your own flour is one of the most powerful ways to take control of your bread. As to which one to buy, I will give this answer some extra attention. It is a question I see several times a day on the interwebs. Everyone has a different opinion about which is best, but it’s usually their favorite based on what they already own rather than any real comparison between options, so I’ll instead mention what I think the most important considerations are when choosing for yourself.
Type of mill: Like their wind and stream-driven cousins, electric stone mills crush and shear grain between profiled millstones. They tend to produce flour with a texture many bakers prefer, particularly for artisan bread. They are generally quieter than impact mills, though still far from silent, and by adjusting the space between the two stones, they are able to produce a wide range of grind consistencies from coarse meal to fine flour. The other major category is the impact mill; these mills use high-speed steel heads to pulverize grain into flour. The most common examples are the WonderMill Grain Mill (~$329) and NutriMill Classic (~$279), and though I don’t own them, their users recommend them highly. They are typically cheaper, faster, often collect flour more cleanly, and can be easier to live with when milling large quantities, but I find them to be ugly, white plastic eyesores, so I wouldn’t own one if it had to live on my kitchen counter. They are also considerably louder, but the flour they produce is excellent and many serious bakers use them happily, so if price is important and your primary goal is efficiency rather than romance, an impact mill deserves consideration.
A third option. For bakers interested in complete self-sufficiency, hand-crank mills remain available from manufacturers such as Country Living and Diamant. They work well, but I view them as specialty tools, emergency tools, or historical curiosities rather than practical everyday breadmaking equipment. Milling enough flour for a pair of large sourdough loaves by hand is an excellent way to discover muscles you did not know you had.
Appearance: My mill lives on my counter. A cheap looking white plastic contraption may work just as well as my beautiful all wood Mockmill Lino 200, but there’s no way I want it out where I have to look at it all the time. If I had an appliance barn or a convenient place to store it, this wouldn’t matter as much, but aesthetics is always high on my list, and wood stone mills win this category hands down.
Weight: This is a key factor if your mill won’t be staying out on the counter. Lugging around a heavy machine will dissuade you from using it.
Noise: I find the stone mill a less annoying sound, but none of these machines is conversation-friendly.
Heat: Unless you are milling very large quantities, you won’t have too much heat to deal with, but a small stone mill can get the flour hot enough to potentially cause oxidation, so it’s better to work in batches of under a kilo.
Mess/collection container: The impact mills tend to collect the flour internally using a removable drawer or bin. This is far less messy than the spouts of the stone mills, which in addition to filling the bowl placed below them, also tend to spray a fine mist of flour everywhere. I use a sack cloth draped over the machine and bowl while milling to keep the dust down, but it’s a potential issue to consider.
Price and quality: Quality, warranty, and build are just as important as price. As you may learn the hard way, things like the KitchenAid attachment are cheap, but they are also loud, inefficient and not built to last. The higher the quality of your mill, the more you’ll use it, the more you’ll enjoy it, and the more bread you’ll bake. This is a long-term investment, so choose the best one you can afford based on milling technology, looks, collection method (dust mitigation), and noise level.
My choice: The mill I use is the Mockmill Lino 200 (~$700). It is a beautiful machine, which matters to me more than it probably should, but it is also a genuinely excellent stone mill. It lives on my counter, mills flour quickly, produces a very consistent grind, and has been completely reliable with minimal upkeep for many years. If I were replacing my mill tomorrow, I would buy the same one without hesitation.
