Peanut butter really is one of the greatest inventions. It’s an incredibly versatile food, perfect for desserts, sandwiches, healthy snacks, or just eating straight from the jar. And in addition to the nutrition value, peanut butter is always great for its shelf life and storage options.
In general, commercial peanut butter does not need to be refrigerated. Opened jars of your everyday, processed peanut butter can sit in a normal pantry for up to three months after opening. Keeping the peanut butter at room temperature also has the added bonus of making it more creamy and spreadable when you use it. However, if your jar of peanut butter is going to take longer than a few months to finish, or if you live in a climate that’s particularly hot and/or humid, it doesn’t hurt to pop the jar in the refrigerator. Once it’s in the fridge, you’ve got about another three to four months to polish it off before it starts to lose freshness.
