It depends on the flour. A friend of mine baked bread, but he also made the flour (and everything really. Not for mass production). His bread took a week to go stale. It was also amazing to eat (not an expert).

He grew his own wheat and had some very specific requirements when making the flour (he didn't own the grind, but he was friend with the owner).

That's all I know. Of course no GMO.
