Frequently Asked Questions
How long does peanut butter last in the fridge?
Peanut Butter usually last 3-6 months (natural; extends life vs pantry) when stored correctly. Treat that as a quality window, then use smell, texture, and visible spoilage checks before eating.

Yes. The usual freezer window is 6-12 months. Freeze in airtight portions, label the date, and thaw in the fridge for the best safety and texture.
