Tag: Refrigerate peanut butter

Unlike its conventional counterpart, which contains added hydrogenated oils to prevent separation, natural peanut butter is made with just peanuts and salt. This simple recipe is precisely why natural peanut butter has to be refrigerated after opening to preserve its fresh, nutty flavor and consistency.

According to the National Peanut Board, an opened jar of conventional peanut butter is safe in the pantry for up to three months. This leads many to ask: **Do you have to refrigerate peanut butter?** The answer is nuanced and depends largely on the type you buy, from processed to natural.
