Our flour is all 100% organic heritage wheat. It is pre-1950s, pre-hybridized wheat. There have been changes in wheat since the 1950’s that make modern wheat less digestible for many people. We use no modern hybridized wheat. We also use a high-velocity milling technology from the 1930’s called the “Unifine mill”. Instead of grinding the grain, the mill shatters it into minute particles, which produces a super-fine flour. It might be helpful to read comments under the various products on our website.
