It is important to invest in a good grain mill as part of your emergency preparations. Since the bulk of most long-term food programs is made up of grain, it is a good idea to have some sort of non-electric means of turning grain into flour and meal.
The best way to store grains and beans is in their whole state. They will last almost indefinitely in this form. Whole wheat was found in the pyramids and it was still edible. However, the best, most efficient way to use these same grains and beans, corn, etc. is to grind them into flour, meal or a cracked cereal consistency. The cooking time is greatly reduced when you grind the grains and beans. They often become more digestible which is a very important consideration during an emergency situation.
This grain mill is easy to use and has an option for motorizing if you want to have fresh grain on a daily basis.
