Keeping Bread Flour Fresh
Store bread flour in airtight, food-grade containers away from heat and direct light. Keeping the flour cool and sealed protects the integrity of the proteins and oils, preventing them from going rancid or attracting pests over time.
The enemy is air, heat, and moisture.
If you buy in bulk, plan for immediate decanting into smaller, manageable vessels. Flour that smells like old cardboard has already lost its vitality.

The deep freeze for long-term survival
If you need to hold onto a large supply for more than six months, seal it in freezer-safe bags and keep it in the freezer to arrest the natural degradation of the wheat oils.
The method.
Seal the bulk package
If you aren't using all the flour at once, fold the original bag tightly and secure it with a heavy-duty clip to prevent moisture absorption.
Decant into storage
Pour your flour into glass or thick plastic containers with silicone gaskets. Do not fill to the very top; leave a half-inch of space to ensure the seal closes fully.
Label and date
Write the date of purchase on a piece of tape on the canister. You want to use the oldest stock first, following a simple rotation.
Find the dark spot
Keep the containers in a pantry or cupboard that stays between 55°F and 70°F. Avoid spots next to the oven or dishwasher where heat fluctuates.
When it doesn't go to plan.
Keep a bay leaf inside your flour container to deter pantry moths.
Always use a dry spoon or scoop. Any trace of water introduced into the container will promote mold growth.
If you move flour from the freezer, let the container reach room temperature before opening it to avoid condensation forming inside.

How can I tell if my flour has gone bad?
Trust your nose. Fresh bread flour should be neutral or slightly earthy. If it has a sour, metallic, or sharp odor, the fats have turned and it should be discarded.
Can I store flour in the original paper bags?
Paper bags are permeable. They allow odors to seep in and moisture to fluctuate, which shortens the shelf life. Transferring to a sealed container is necessary for anything kept longer than a month.
