How We Chose the Best Grain Mill for Sourdough
To build this guide, we compared grain mills and grains sold on Amazon US by milling mechanism (impact, steel burr, stone or blade), motor power or hand effort, flour fineness range, hopper size, noise, cleaning and warranty. For grains we compared wheat type, certifications, bag size and grower. We then read patterns in verified-buyer reviews and flagged products with few ratings or ratings shared across sizes.
Flour is a raw agricultural product, so keep mills clean and dry, store grain and flour sealed, and always bake or cook flour before eating it, in line with USDA Food Safety and Inspection Service cleanliness guidance. Our method is explained on the How We Test page; this is a research-based guide, not a lab test.
Buying Guide: Milling for Sourdough
Feed the Starter
A little fresh whole grain flour boosts starter activity.
Hydration
Fresh whole wheat absorbs more water; add water gradually.
Faster Fermentation
Expect a quicker rise with fresh-milled flour; watch the dough, not the clock.
Sift for Lighter Loaves
Sifting out some bran gives a lighter crumb.
Blend Grains
Mix hard wheat with khorasan or spelt for flavor.
Tips for Milling Flour at Home
