Peanut butter can go bad, but in general, it has a long shelf life.

Moststore-bought peanut buttercontains stabilizers that keep it fresh for longer.

Unopened, commercial peanut butter can last up to two years.

Once opened, though, peanut butter lasts about three months.

After the best-by date passes, it may still be safe to eat.

However, the quality of the product cannot be guaranteed.

The most obvious sign that peanut butter has gone bad is a strong, rancid scent.

You want a fresh, nutty aroma, not a bitter or soapy odor.

Other signs of spoiled peanut butter include mold growth and changes in its color or texture.

Over time, natural peanut butter may show a separation of its oils and solids.

Best Way to Store Peanut Butter

Storing peanut butter properly can help it last longer.

While placing it in the fridge is not a must, it can extend peanut butter’s shelf life.

The downside is it can be hard to spread peanut butter after refrigeration.

Additionally, keeping the jar’s lid tightly closed will minimize its exposure to air and bacteria.
