Should Flour Be Kept in Fridge?

Flour will keep for at least one year. To keep flour super-fresh, store it in the freezer or fridge (an airtight container is still best). It might be an especially good idea to do so if your house runs warm, if you live in a humid climate, or if you simply don't go through flour very quickly.

Is it bad to refrigerate flour?

How long can you keep flour? Any white flour, like all-purpose or self-rising flours, stored at room temperature should be discarded after three months; if stored at a cooler house temp, it can last six months. In a fridge, the flour has one year, and in the freezer, it has two.

What flour should be refrigerated?

Store whole grain flour in the freezer or refrigerator, as far from the freezer/fridge door as possible. Un-milled whole grains (e.g., wheat berries, rye flakes, rolled oats) have a longer shelf life than whole grain flours.
