Grain Storage Guide

General Guidelines | Recommended Storage Methods for Whole Grains

General Guidelines

Like many other foods, grains are perishable; however, the shelf life of grains is usually much longer than that of most foods. To ensure optimum freshness and shelf life, it is always best to buy grains that are well packaged and well sealed. Grains should always look and smell fresh. When looking for grains that are not as commonly used as others, freshness may be optimum when the grain is purchased from a specialty shop or natural food store than from a supermarket. This is because an uncommon grain (in the United States), such as quinoa, is purchased much more often in a specialty shop by people looking for that specific item than by the average customer in a large food store.
	For home storage, keeping grain sealed in containers with tight fitting lids is often the best method for keeping grain fresh, especially when the container of grain is stored in a cool, dry, and dark location. A sealed container is very important for maintaining freshness and reducing the possibility of infestations.
An important point to remember is that whole grain does not keep as long as pearled or refined grain, because the germ portion of the kernels can cause the grain to become rancid over time. Never use grain or grain products that do not look or smell the way they should. It is best to buy smaller quantities of grains and grain products if you are finding it necessary to continually discard large amounts of grain due to spoilage.

The refrigerator can be a good place to store grains, especially in warm weather; however, using a sealed container is even more important in this case in order to prevent the grain from absorbing moisture and odors and flavors from other foods stored in the refrigerator. For long-term storage, the freezer compartment is the best place to store grains, but again, the grains must be in a sealed container or tightly wrapped.

Recommended Storage Methods for Whole Grains

Amaranth

Storage Containers

It is best to store amaranth in a tightly sealed container (preferably a glass jar).

Storage Locations

The best storage location for amaranth is a cool, dark, dry location. Do not store amaranth in a cabinet near a stove, oven, or dishwasher. The heat from these appliances will greatly reduce the shelf life of the grain.

Shelf- Life

Amaranth can have a shelf life of up to one year if properly stored.

Other Considerations

Amaranth will not keep well if it is stored in a warm location or if it is exposed to sunlight. The flavor and aroma of amaranth will become bitter if it is stored improperly or if it is stored for an excessively long period of time.

Barley

Storage Containers

For cabinet storage, it is best to store barley in sealed containers of plastic or glass. The grain should be tightly wrapped for refrigerator or freezer storage.

Storage Locations

The best storage locations for storing barley are cool, dry areas away from heat and light, or store it in the refrigerator or freezer.

Shelf Life

Barley can have a shelf life of up to one year if properly stored.

Other Considerations

It is best to store barley in the refrigerator or freezer during the summer months or year-round in hot climates, but it must be tightly wrapped to reduce the possibility of the grain absorbing moisture from the refrigeration compartment.

Buckwheat

Storage Containers

Buckwheat should be tightly wrapped for refrigerator or freezer storage.

Storage Locations

Again, it is best to store buckwheat in the refrigerator or freezer.

Shelf Life

The shelf life of buckwheat can be up to 2 to 3 months in the refrigerator and 6 months or longer in the freezer when stored correctly.

Other Considerations

Buckwheat must be tightly wrapped to reduce the possibility of the grain absorbing moisture from the refrigeration compartment.

Corn

Storage Containers

For cabinet storage, sealed containers of plastic or glass are the best for storing whole corn kernels and popcorn.

Storage Locations

Choose a cool, dark, dry location for storing dry corn grain products.

Shelf Life

Dried whole corn kernels and popcorn may keep for several years if properly stored.

Farro

Storage Containers

For cabinet storage, sealed containers of plastic or glass are the best for storing farro. The grain should be tightly wrapped for refrigerator or freezer storage.

Storage Locations

Cool, dry locations away from heat and light, or refrigerator or freezer storage are the best storage locations.

Shelf Life

Farro may keep for up to one year if properly stored.

Flaxseed

Storage Containers

An airtight container that does not permit light to pass through is the best type of container to use for storing flaxseed.

Storage Locations

Flaxseed should be stored in a cool, dark, dry location away from heat.

Shelf Life

Flaxseed will last several months if properly stored.

Other Considerations

Exposure to light will deteriorate the effectiveness of the omega-3 fatty acids in the flaxseed, which are so effective in reducing cholesterol; therefore, it is very important to store flaxseed away from light if you wish to enjoy the benefits of this heart-healthy seed. When shopping for flaxseed, look for packaging that protects the seeds from exposure to light.

Job's Tears

Storage Containers

Airtight containers of plastic or glass or tight wrapping are best for storing Job's Tears.

Storage Locations

The best place to store Job's Tears is in the refrigerator or freezer.

Shelf Life

Job's Tears will keep for several months in the refrigerator and six months or more when stored in the freezer.

Kamut® Grain

Storage Containers

Sealed containers of plastic or glass are the best the best storage containers for keeping Kamut® fresh.

Storage Locations

Store Kamut® in a cool, dry location, such as a kitchen cabinet away from the heat of a stove or oven.

Shelf Life

Kamut® may keep up to one year, and possibly longer, when it is properly stored.

Other Considerations

Whole-grain Kamut® usually lasts longer than whole-grain wheat, because it has a lower moisture content than wheat.

Millet

Storage Containers

For cabinet storage, sealed containers of plastic or glass are the best for storing millet. The grain should be tightly wrapped for refrigerator or freezer storage. A completely filled and sealed glass jar also works well for refrigerator storage.

Storage Locations

The best locations for storing millet are a cool, dry cabinet or the refrigerator or freezer.

Shelf Life

Millet will keep for about two months when properly stored in a kitchen cabinet, four months in the refrigerator, and six months or longer in the freezer. (Note: partially filled containers can pick up moisture in the refrigerator, so it is important to fill the container completely when storing millet in the refrigerator.)

Other Considerations

Millet can become rancid quickly if it is not stored properly.

Oats

Storage Containers

Oats should be stored in sealed containers of plastic or glass.

Storage Locations

A cool, dry, dark cabinet is the best location for storing oats.

Shelf Life

Oats will keep for one year or longer if stored properly.

Other Considerations

The high level of antioxidants in oats helps to prevent spoilage; therefore, oats will keep for very long periods if properly stored.

Quinoa

Storage Containers

Sealed containers of plastic or glass are best for storing quinoa.

Storage Locations

The best location for storing quinoa is in a cool, dark, dry cabinet.

Shelf Life

Quinoa will stay fresh for one year or longer if properly stored.

Other Considerations

Quinoa will keep for longer periods (over a year) if it is stored away from sunlight and heat.

Rice

Storage Containers

Tightly sealed plastic or glass containers are best for storing rice.
