Benefits of Milling Your Flour

Home flour milling offers substantial benefits beyond simple bread making. When they understand these advantages, bakers can make informed choices about their sourdough experience and equipment selection.

Improved Nutrition and Flavor

Home-milled flour offers much better nutrition than store-bought alternatives. Fresh-milled flour retains 40 of the 44 essential nutrients required for life and packs a powerful nutritional punch. Fresh milling prevents nutrient loss through oxidation. Studies show that:

• Nutrients begin degrading within 24 hours of milling
• 40-45% of nutrients are lost in the first day
• After three days, over 95% of essential nutrients are lost through oxidation

Fresh-milled flour creates exceptional-tasting sourdough bread. Aromatic compounds in newly ground grain create complex flavors that taste nutty and cream-like. These qualities make the bread-eating experience truly memorable.

Cost Savings

The economics of home milling versus store-bought flour reveals the most critical long-term savings:

The original investment in a grain mill requires upfront costs, but knowing how to store whole grains creates economic advantages. Whole grains maintain their nutritional value for years with proper storage that eliminates waste from expired flour and reduces purchase frequency.

Versatility in Flour Types

Home milling creates endless possibilities for sourdough baking. You can try different grains to make unique flour blends.

Ancient grains like einkorn, spelled, and Kamut have unique flavors and health benefits. Hard white wheat makes lighter, softer bread, and hard red wheat gives you hearty, full-bodied flavors. You can adjust your mill’s settings to make everything from fine pastry flour to coarse meal that suits different baking needs.

Fresh-milled flour’s enzymatic activity improves sourdough fermentation. This natural process helps develop the dough and creates a better texture and crumb structure. You can control your sourdough’s characteristics by picking specific grain varieties to get your desired protein content.

Stone Mills

Stone mills grind grain into flour using two millstones, a centuries-old method. These machines run at 450-500 watts and produce flour at a steady pace. Due to this slower grinding method, the grain’s natural oils and nutrients remain preserved.

Stone mills come with several distinctive features. Users can adjust the gap between stones to create different textures. The mills operate at lower temperatures and excel at producing everything from coarse to ultra-fine flour. Their design works best with small to medium batches.

The mill’s grinding stones need occasional dressing to perform at their best. Most stone mills feature self-sharpening grooves that maintain consistent grinding patterns for years.
