Storing Whole Grains

by Cassidy Stockton in Featured Articles, Whole Grains 101

If you asked Bob how to store whole grains, he’d tell you to buy an extra fridge. Put it next to your regular fridge and fill it with all of your whole grains. Most of us don’t have the ability to add an extra fridge into our lives. Even if someone gave me a free fridge and offered to pay the increase in my electrical bill, I couldn’t fit an second fridge into my kitchen. Excepting those who are able to have a fridge or freezer with spare room, the rest of us are stuck scratching our heads and hoping our grains will be fine. Here’s a rundown on where to store whole grains. I hope it will give you some insight and inspiration for your own kitchen and maybe frees up a little room in your freezer.

Whole grains are best kept in the fridge or freezer to prevent rancidity. True. They are. BUT, this is more important when a grain has been broken up in some way- be it milled into flour, cracked into cereal or flaked like oatmeal. Whole grains themselves (brown rice, wheat berries, quinoa, etc.) are more shelf stable that we think. Some of these grains can last many years without going rancid. That’s how nature made them. Most whole grains that have been broken up in some way will last up to two years, sometimes longer, without spoiling.

Here is a quick breakdown of where to store products.

  • Whole Grains (wheat berries, brown rice, quinoa, millet, etc) used once a month: room temp
  • Whole Grains used less than once a month: freezer
  • Dried Beans: room temp
  • Flour, Cereals, Cracked Grains used once a week: room temp
  • Flour, Cereals, Cracked Grains used less than once a month: fridge or freezer
  • Baking Mixes: room temp or fridge, do not freeze
  • Refined Grains, Flours and Cereals (white flour, white rice, etc): room temp
  • Items that should always be kept in the fridge or freezer: 
    • Almond Meal
    • Hazelnut Meal
    • Coconut Flour
    • Wheat Germ
    • Rice Bran
    • Flaxseed Meal (whole seeds are fine at room temp)
    • Hemp Seeds
    • Active Dry Yeast (do not freeze)

I recommend airtight containers for everything, but at the very least use airtight containers for things left at room temperature. Bugs love whole grains and nothing keeps a bug out quite like a mason jar. Plus, mason jars filled with whole grains and beans are very pretty and make a lovely addition to your decor. You can make your own labels like we did with the display above, or cut out labels from our bag and adhere them to your jars. At my house, I have these labels (below) that include basic cooking instructions. While I might have the recipe down pat, others in my house do not and I want to eliminate the “I didn’t know how to cook it” excuse, if you know what I mean.


I hope this has been helpful. Do you have any insights from your kitchen on how to best store grains?

  1. I was wondering if you could make apricot kernel meal/flour it is rich in cancer fighting vitamins b15 and b17 and not everyone can chew the kernels. Please think about it. I would love to be able to sprinkle it on the oatmeal for the elderly people I care about and even for my own family 🙂 It is so important to get these two b vitamins back in to our natural diet 🙂 Thank you for all you do.

    • Dr Grace,

      Thank you for your kind words. We have not heard of making apricot kernel meal, but we’ll pass along the request. I always thought they had some negative effects, but perhaps that is peaches. We do not sell the labels, but if we do start in the future, I’ll let you know. We just whipped them up for this post.

  2. P.S. I forgot to ask. do you have these wonderful jar labels for sale somewhere? I would also love to use these labels for my containers. I only use YOUR flours and beans only your brand, it would be so amazing to have labels with little instructions on the side on basic preparation 🙂 To this day I have to keep your labels with the recipe inside my containers. These labels would help tremendously.

    • The instructions are for storing grains after opening, but if you aren’t using a grain quickly and you haven’t opened it, we recommend the freezer. A grain can still go bad, even if it hasn’t been opened.

  3. I picked up my first bag of your Flaxseed Meal from a grocer who had it displayed to the top shelf in the baking goods aisle rather than refrigerated. Is it probably degraded in some way? Less nutrients or harmful?

  4. We have bought a number of your flours but three bags of them have not yet been opened. We stored them in the closet and almost forgot about them until today. They are unopened but in some cases the sell-by date has passed. Is it safe to still use them ? They are as follows:
    Quinoa Flour
    Coconut Flour
    Almond Meal Flour

    As noted, they are all unopened but we’ve had them stored in the cabinet for a couple months.

    • Deidre,

      It’s possible, but you’re going to have to open them and smell. Quinoa flour will smell funky anyway, but if it smells sour, don’t use it. Coconut flour should have a slight, sweet coconut smell- again, if it smells sour, don’t use it. Almond flour, this is the one with the highest risk of rancidity- if it smells off, don’t use it. If it smells sweet and almondy- it’s good to go.

  5. Our family buys your wheat germ from every week. After opening the package, we place the rest of the wheat germ in a vacuum container and vacuum out the air and place it in the refrigerator. Over a week or two we open the container six or seven times and complete the vacuuming process each time.

    Is there any risk of the wheat germ going rancid during that period?

    Is it best to keep the wheat germ in the refrigerator or freezer? Does freezing it impact nutritional benefits?



    Ps we love all your products

  6. Cassidy,

    Could you clarify for me the “Sale By Date”…..Is this to be understood to be the same as “Best By Date”?


  7. I’m so bummed! When I moved to VA from NJ I could no longer find my favorite hot cereal (Bob’s 6 grain) and so I ordered it on Amazon. As much as I love it, I don’t eat it every day and when I went to open the last of the 4 bags that came in my Amazon order 6 months ago, it smelled and tasted funky. Most likely gone rancid despite the sell-by date not being until October 2016.

    We buy all of our beans from Bobs red mill and like to jar them. Any chance you can share the nice label seen in your photo?
