Hi Cindy!!

How long you can store your flour depends on what type of flour you are storing and how you are storing it. Refined flours like all-purpose can last 1-2 years while whole grain and alternative flours last for around 6 months in the refrigerator. You will know your flour has gone bad if it has a sour smell or bitter taste. Airtight storage also helps keep your flour fresh and bug free!

Here is a quick guide on how to store your flour:


Refined flours are made from wheat that have had the germ and the bran removed before crushing. This means there is less oil in the flour which gives refined flours a longer shelf life.

Types: All-purpose, self-rising, bread, pastry
Storage: A cool, dry place
Shelf life: 1-2 years


Whole grain flours retain the germ from the seen which adds nutrients and oil. Exposing oil to air causes it to oxidize which may make it become rancid.

Types: wheat, spelt, teff, quinoa, millet, amaranth, barley, ancient grains, buckwheat, oat flour, medium or dark rye
Storage: Refrigerator or freezer
Shelf life: a few months


Types: nut meals and flours, coconut flour, wheat germ, rice bran, flaxseed meal
Storage: refrigerator or freezer
Shelf life: 6 months in the refrigerator, 12 months in the freezer
