You can freeze flour in ziplock bags. Also, you might consider
purchasing 5 gallon buckets. You can purchase a lid called a “gamma
lid” that is air tight and has a screw on/off feature.
Hae you considered just buying wheat and a mill and grinding your own
wheat? The longer it sits already ground, the less nutrients it has.
If you need help finding a gamma lid or bucket, I have a friend here
locally from whom we buy our wheat and she does ship products,
including the gamma lids, but I am not sure of the details. Her email
is:
edie@wildblue.net.
Enjoy your bread! I am sure it is delicious!
