When you cut it. Bind it into sheaves, and allow it to dry in the open or in a shed with plenty of air circulation. It is important to get the harvest, drying, and separate the wheat from the chaff done and avoid rainfall during that time.
I just use the blender or an electric coffee grinder to make the flour as I need it.
