How Long Do Raisins Last? Do Raisins Go Bad?


Raisins give you great bang for your buck because they will last way longer than you want them to. They have a relatively long shelf life and will serve their purpose well.

They last for:

  • About 3-5 months in the pantry if opened
  • 6 months in the pantry if unopened
  • 9-12 months in the fridge (both opened and unopened)
  • Indefinitely in the freezer

These dried grapes can last long enough in the pantry to be consumed. However, if you want a little more oomph out of your raisins before they go bad, it is best to freeze them. Refrigeration is also possible, but they are better off being frozen.

If frozen, they will last indefinitely. Keep in mind that while they do last incredibly long when frozen, the taste will degrade with time. Looking at it realistically, it will be about 1.5-2 years before they start to lose their scrumptious flavor.

In this aspect, raisins somewhat similar to dried beans, as the latter also last indefinitely but start to lose flavor over time.

How to Tell If Raisins are Bad? Raisins Shelf Life!


Raisins do not exactly ‘spoil’ or go bad like traditional fruits such as bananas and pineapples. Instead, they lose moisture and taste, making them not worth consumption.

Here are some signs to indicate raisins are losing their freshness:

  • Sour smell
  • Growth of mold
  • Hardening

Raisins lose their moisture and tend to harden, but that can be remedied to an extent by letting them simmer in hot water or wine. Other than that, mold does not typically grow on dried fruit or dried beans, but in humid areas, moisture is a natural consequence, so it is best to keep an eye out for any growth on the raisins.

A thing to note is the aroma of food items. Raisins normally have a tart or fruit-like smell to them, but if they spoil, they will have a far sourer smell.

    • The short answer is no, you’ll digest it like any other food, and as long as you’ve got a relatively healthy immune system, the most you’ll experience is some nausea or vomiting due to the taste/idea of what you’ve just eaten.
