How Long Can You Leave Peanut Butter Unrefrigerated?
Peanut butter can be kept unrefrigerated for several months as long as the jar is tightly sealed and kept in a cool, dry place. Natural peanut butter, however, may have a shorter shelf life and should typically be refrigerated after opening to prevent spoilage. It is always best to check the expiration date and follow any storage instructions on the packaging for optimal freshness and safety.
