Common questions

How long does peanut butter (natural) last in the fridge?

12 months from the date of purchase. 3–4 months after opening.

Throw it out if it smells off, feels slimy or sticky, shows mold, or has changed color. Storage times assume it was handled safely and kept cold the whole time.
