Can you vacuum seal flour for long term storage?

Yes, you can vacuum seal flour for long-term storage to significantly extend its shelf life, preventing pests and moisture, but you must avoid getting flour dust into the vacuum sealer by first placing it in a brown paper bag, freezing it beforehand to kill pests, and then vacuum sealing the bagged flour in a food saver bag or mason jar. This method can preserve flour for years, far beyond its typical shelf life, making it ideal for long-term food preservation.

How long will flour last if it's vacuum sealed?

Vacuum-sealed flour can last significantly longer than in its original packaging, extending shelf life from months to 1 to 2 years for white flour, and potentially even longer (up to 20 years in ideal, cool, dark conditions with oxygen absorbers for long-term storage), though whole grain flours last less time due to oils, often around 2 years even vacuum-sealed. Proper sealing (removing oxygen/moisture) and cool, dark storage are key, but always check for rancid smells or pests before use. 

What's the best way to store flour for long term?

For long-term flour storage, the best method involves airtight, hard-sided containers (glass/heavy plastic), placed in a cool, dark, dry location, with freezing being ideal for whole grains and nuts to protect oils, while refined white flour can last longer in a cool pantry.
