The good enough method: Put nuts in a glass container, ideally one with as little empty space as possible. Store sealed nuts in the freezer. “Keeping nuts at freezer temperatures dramatically slows down the rate that oxidation occurs,” says McNeil.

Light, oxygen, and heat are the enemies of nuts. Storing them in an airtight container in the freezer helps to limit their exposure to all three of these elements and slow the rate of spoilage.

If a nut is only slightly stale, says Kanney, it can usually still be toasted to revive some of its previous glory and (crunch). However, Kanney says, “If a nut has spoiled or gone rancid, recognizable by a sour or bitter flavor, the nut is no longer good and should be thrown away.”

Avoid storing nuts near heat sources like stoves, ovens, or direct sunlight. Instead, choose a cool and dark storage location to extend their shelf life.

"Nuts have a wide range of fat contents," says LaMarita. Almonds, walnuts, and pistachios are lower in fat, so they'll generally last longer than nuts higher in fat, like macadamia nuts, pine nuts, cashews, and Brazil nuts, all of which will go rancid quicker, says LaMarita.

Raw nuts can be stored in an airtight container in a cool dark place for six to 12 months. The fridge or freezer is ideal. Nuts can be refrigerated for up to four months and frozen for up to six months. Store ground almonds in an airtight container in a cool dark place for a couple of weeks.

Mistake #2: Storing Them in the Pantry

According to Lindsay, you can keep an unopened bag of shelled or in-shell nuts in the fridge or freezer for two years (!). Even if the bag's been opened, shelled nuts should last an entire year, and in-shell nuts will last about a year and a half.

At room temperature, nuts and seeds can start to go bad after anywhere between one and three months, though some brands will advertise longer shelf lives than that. If stored in the refrigerator, however, these healthy fat sources can last up to six months.

That's because when chopped, roasted, or ground, nuts release their oils. These oils are then exposed to more oxygen, which makes nuts go rancid more quickly.
