Quick answer

Wheat berries are whole wheat kernels. Stored dry and cool, they keep for years and can be milled into fresh flour. Utah State University Extension says about 150 lb supplies an adult for a year, and hard red and hard white wheat (11 to 15% protein) make bread flour while soft white wheat (9 to 12%) suits pastry, cakes and pasta. Palouse Brand sells all three from its Washington farm: Red Winter Wheat in a 5 lb bag, Hard White Wheat in a 25 lb gasketed storage bucket, and Soft White Wheat in a 5 lb bag.

Which wheat class to store

Wheat is sold by class: color, kernel hardness and growing season. USU Extension groups hard red spring, hard red winter and hard white wheat at 11 to 15% protein, the high-gluten wheat for bread flour. Soft red and soft white wheat run 9 to 12% protein and suit pasta, cake, biscuit, cracker and pastry flours.

Most storage plans center on a hard wheat for bread. USU notes white wheat kernels are plumper and larger than red. A smaller amount of soft white gives you pastry flour for biscuits and pancakes. USU also notes that gluten weakens in storage and can lose half its raising power after several years, so rotate your stock and use the oldest first.

Three Palouse wheats compared

Wheat	Size	Protein (USU class)	Use
Red Winter	5 lb bag	11-15%	Bread flour
Hard White	25 lb bucket	12-14% (Palouse)	Yeast bread
Soft White	5 lb bag	9-12%	Pastry, cereal

Sizes and uses are from Palouse Brand; protein ranges are USU Extension's class figures except where Palouse lists its own.

How much wheat to store

USU Extension estimates about 150 lb of wheat supplies one adult for a year, and a three-week emergency supply is about 5 to 10 lb per adult. Children 8 and under need about half those amounts.

A practical way to build up is to start with a few small bags, learn to cook and bake with them, then add bulk containers once you know your household will use whole wheat. Stored grain only helps if you can turn it into food, so pair it with a grain mill and recipes you already make.

Packing wheat for long-term storage

USU says to store wheat in moisture-proof, food-grade packaging such as Mylar-type bags, polyethylene bags, plastic buckets or #10 cans, keeping in mind that rodents can chew through plastic bags. Splitting wheat into about 10 lb bags makes it easy to rotate and inspect, and keeps one contaminated bag from spoiling the whole supply. Several bags fit inside a 5-gallon bucket.

Oxygen-free storage is not required unless insects are present, USU says. Sealing wheat in Mylar bags or #10 cans with oxygen absorbers kills adult insects and keeps larvae from surviving. Polyethylene bags and plastic buckets will not hold an oxygen-free atmosphere over time. Label every container with the wheat class and the date.

Temperature, moisture and insects

USU calls 40 to 60°F the ideal storage range for home grain. Freezing does not harm stored wheat; warmer storage speeds the loss of the grain's ability to sprout but only slightly speeds the loss of food value. Moisture matters more: above 12% encourages degradation, above 15% lets mold grow. Keep containers off the floor, especially concrete, which can wick moisture into them.

For insects, USU recommends freezing 1 to 15 lb bags for 2 to 3 days and repeating if needed, dry ice in buckets, vacuum sealing, or oxygen absorbers in Mylar or cans. It does not recommend insecticides, heating, or bay leaves, nails or salt, which it says have no effect on insects or eggs.

How long wheat berries last

USU's rule of thumb is to rotate stored wheat so none is older than 5 years, using it regularly and replacing what you use. It adds that older wheat has still made acceptable bread, citing a BYU study of wheat stored in #10 cans for 32 years.

Do not buy seed wheat for food storage. USU warns seed wheat may carry toxic chemical treatments.

Which one to buy

Choose the Palouse Hard White 25 lb bucket for the core of a bread-wheat supply in a ready storage container. Choose the Red Winter 5 lb bag for red-wheat bread or to test before buying in bulk. Add the Soft White 5 lb bag for pastry flour and cooked whole grains. For milling, see our grain mill for flour guide.

What to look for when you buy

Questions people ask

How long do wheat berries last in storage?

USU Extension suggests rotating so no stored wheat is older than 5 years, though older wheat in #10 cans has still made acceptable bread.

How much wheat should I store per person?

USU estimates about 150 lb per adult for a year, or 5 to 10 lb per adult for a three-week emergency supply, and half that for children 8 and under.

Hard red or hard white wheat for bread?

Both are high-gluten bread wheats (11 to 15% protein, per USU). Palouse lists its hard white at 12 to 14% protein for yeast breads; the choice mostly comes down to the color and flavor of whole wheat bread your household prefers, so try a small bag of each.

Do wheat berries need oxygen absorbers?

Not unless insects are present, USU says, but sealing wheat in Mylar or #10 cans with oxygen absorbers kills adult insects and keeps larvae from surviving.
