How to store homemade granola?
Although ours rarely lasts for more than a week, we typically just store it in an airtight container with the rest of the cereal.  I would imagine the fat could eventually go rancid, so if you need to store it for weeks or months, either refrigeration or freezing should work.  You'll still want the airtight container, however, to prevent any fridge funk from tainting the taste.
