Besides wheat, there are many other grains that can be stored to add variety and nutrition. The ones that I have chosen are:
Rolled and Quick Oats
Rice--White rice keeps better. Brown rice can be frozen or oven canned.
Rolled and Pearled Barley
Corn Meal, Popcorn and Corn for grinding and growing
Split Peas
Quinoa
Alfalfa Seeds (for sprouting) (Old seeds don't sprout. Use for chicken feed or mulch.)
Mung Beans (for sprouting). Same with old beans.
Triticale
Rye
Millet
Macaroni
Chia Seeds
Flax Seeds
Lentils
6-Grain Mix
Note that 20-60 year old wheat may not sprout. I have wheat in cans (about 30 years old) that does not sprout. I have many empty canning jars, so I stone ground some of it into flour and oven canned.
Oven canning instructions: fill clean quart or 1/2 gallon jars with freshly ground flour. Place in the oven on a cooky sheet at 200 degrees for an hour. Heat the lids (used lids are fine) in a container in the same oven. (Not rings). Then remove the jars carefully one at a time using hot pads. Put the hot lids on each bottle and then rings. Tighten. They should seal within a few hours. If they don't, use those bottles first. The flour will still keep a long time even if the lids don't seal.
