Grain, Seed & Flour Storage
The storability of grains, seeds, nuts and flours varies tremendously.
This page presents a chart showing approximately how long these various
items can be safely stored under different conditions. Of necessity the
given times are approximate because they are dependent on exact conditions
of storage and how long they have already been stored by time you acquire
them. You should develop the ability to detect rancidity by smell as a
- Vitamin Loss: Some of the grains and seeds
are listed with very long storage times, but vitamin loss is very significant
by 3 years and vitamins are essentially gone by 5 years.
- Beans: Technically beans will keep for
many years without spoiling - BUT - in practice a year is about maximum.
Beans that have been stored too long simply will not soften in cooking.
They are edible, but not pleasantly so.
- Storage Conditions
- Sealed: This means stored very dry in a tightly sealed
fairly full container kept away from light and in as cool and dry a place
as you can manage. Any compromise on these conditions will significantly
reduce storage life.
- Fridge: Packed very dry in an airtight bag or other sealed
container and maintained between 32° and 40°F.
- Freezer: Packed very dry in an airtight bag and kept
frozen at less than 10°F.
- Rancidity: Not only does rancidity degrade flavors and
produce unpleasant odors, products of rancidity are suspected carcenogens,
so consumption of rancid products should be avoided.
Storage times here are approximate and may vary depending on storage
conditions and on how old the seeds or flour was at time of purchase.
