What is the storage life of freshly milled grains?

Any flour milled from whole grains contains the germs. These are rich in oils (which is one of the benefits of freshly ground flour) and are prone to oxidation or – more commonly – going rancid. Depending on a few factors you can expect a storage life of 4 to 6 weeks. The main factors that influence the oxidation are:
Temperatur, radiation (light, espec. UV), and surface.

Since flour has a huge surface compared to the intact grain the oils can react much easier and faster with air. To slow down this process, the best way is obviously not to grind the flour until you need it. However, if you decided to mill larger quantities at a time you want to make sure that the flour is stored in a dark, dry place, as cool as possible.
