How to Store our Flours


We carefully stone-mill your flours for maximum flavor and nutrition, and keep them cool every step of the way to preserve all of those great nutrients and taste. The cooler you keep them in your home, the better they'll be! Unlike industrial roller mills, our stone mill gently crushes all parts of the grain so that the nutrient-rich bran and germ are incorporated into the flour instead of being stripped away. These nutrients are perishable and can affect flavor over time.

Here are our recommendations for keeping your Janie's Mill flour as fresh, tasty, and nutritious as possible.

1. Store in your Fridge or Freezer

Because Janie's Mill flours contain perishable oils and vitamins in the germ and bran, we recommend you purchase our fresh-ground flour in small amounts, and store the unopened bags in a cool (below 60°F) dry place, ideally in your fridge or freezer. 

Even our sifted flours contain 70% to 90% of the whole kernel, including the healthy but perishable oils. No matter which Janie's Mill flours you use, you get the best flavor and nutrition when you keep them cool and use them quickly!

Our whole grains are more shelf-stable, but we still recommend storing them in a cool, dry place for optimal freshness and flavor.

2. Keep Airtight

Once opened, Janie's Mill products should be transferred to air-tight containers and stored in a cool, dry place -- ideally your refrigerator or freezer (see above). 

3. Use Within 9 to 12 Months

You'll get the best flavor and nutrition when you use our flour soon after it is milled. If you store it at room temperature, you should use it within one month. If the products are in your refrigerator, they will keep well for 9 to 12 months

4. Freeze for Longer Storage

If you freeze your flour, it will keep well almost indefinitely! If you purchase larger quantities that won't be used right away, put in an air-tight container in your freezer for the best taste and nutrition.
