Does Peanut Butter Expire?

Now, let’s address the pressing question: “Does peanut butter expire?” The short answer is yes, but the shelf life of peanut butter depends on various factors, including storage conditions and whether it’s natural or commercial peanut butter.

How to Store Peanut Butter

  • Natural Peanut Butter: Natural peanut butter, made with just peanuts and sometimes salt, tends to have a shorter shelf life due to its lack of preservatives. When stored properly in a cool, dry place, an unopened jar of natural peanut butter can last up to 6-9 months. Once opened, it should be refrigerated and consumed within 2-3 months for best quality.

How Long Does Peanut Butter Last?

  • Commercial Peanut Butter: Commercial peanut butter, which often contains added oils, sugars, and preservatives, typically has a longer shelf life. An unopened jar of commercial peanut butter can last up to a year when stored in a cool, dry place. Once opened, it should be consumed within 3-4 months if stored at room temperature or up to 6-9 months if refrigerated.

How to Tell If Peanut Butter Has Gone Bad

  • Signs Peanut Butter Has Gone Bad:
    • Odor: If peanut butter develops an off-smell, it’s a clear sign that it has gone bad.
    • Texture: Mold growth, a gritty texture, or separation of oil on the surface are indicators that the peanut butter is no longer safe to consume.
    • Taste: A rancid or sour taste is a definite sign that the peanut butter has spoiled.

Understanding how to store peanut butter properly and recognizing the signs that peanut butter has gone bad is crucial for maintaining its freshness, flavor, and safety. Whether you’re enjoying it in many delicious recipes, ensuring your peanut butter is fresh and properly stored is essential.
