Knowing when to refrigerate peanut butter can be a bit of a head-scratcher, especially if there aren’t any instructions on the jar’s label. So, does it go in the fridge or doesn’t it? The bottom line is: It depends.

Processed brands of peanut butter are made to have a long shelf life thanks to the addition of stabilizers like palm oil and hydrogenated oils, so once opened, they’re fine to store in a cool, dry cupboard. According to the National Peanut Board, opened jars of commercial processed peanut butter stored this way will last for two to three months. After that, they recommend storing jars in the refrigerator, which will extend their shelf life by another three to four months. Unopened jars will last six to nine months in the pantry, but be sure to check the jar’s expiration date, too.

If you buy all-natural peanut butter — these are the ones that are unrefined and likely made with just ground peanuts and salt — you’ll want to store jars in the fridge after opening, since the oils can go rancid very quickly. That said, if you go through jars quickly (within a few weeks), it’s fine to leave jars of all-natural peanut butter stored in a cool, dry place. If you’re not refrigerating your all-natural peanut butter, it’s important to never double-dip or introduce jelly-smeared knives to the jar; if you notice any mold or strange smells, toss the jar.

When it comes to peanuts (shelled or unshelled), the National Peanut Board says they’ll last in a bag or sealed container for a month or two. But because nuts have a high oil content, they tend to go rancid quicker if they’re not kept cool. Store nuts in the fridge to extend their shelf-life to four to six months.

Want to extend nuts’ shelf-life even further? Chef Carla Contreras, founder of the online cooking school Cook+Chop and a former personal chef, recommends freezing them. Since nuts have such low water content, they won’t freeze. “I am crazy about storing nuts and seeds in the freezer. It extends their shelf life,” Contreras explains. “I take out small amounts and store them in glass containers in the fridge and replenish as needed.”
