As we mentioned earlier, M&Ms come in different variants, and their shelf life can differ with each variant.

For instance, an unopened pack of M&M Peanuts can last for six months in your pantry, while you can expect 12 months of storage life from the M&M Mint beyond the “best by” date. Similarly, you will get a different shelf life for other M&M variants.

M&Ms are similar to other sweets and generally come with a best before date rather than having an expiration date.

This distinction means that you can consume your favorite M&Ms safely even if the recommended best before date has elapsed. If you want to enjoy more shelf life, then plain M&Ms are the best to consider as they can last longer in the freezer.

As M&M candies come with extra coating, they last long beyond their best before date. However, they can lose their taste and become less enjoyable to your taste buds.

Below are a few measures that you can follow to increase their shelf life:

  • Storing your M&Ms in a cool and dry place ensures that they stay fresh for longer, retaining their mouth-watering flavors.
  • Never store them in a warm place.
  • Store M&Ms at 75 degrees Fahrenheit.
  • Storing them in an airtight container or original packaging prolongs their shelf life.
  • Keep M&Ms away from moisture by sealing them with a plastic wrap.
  • If you want to preserve their taste longer, keep them in your freezer using an airtight freezer-safe container.

Following food safety techniques and practicing hygiene is a must for healthy living, and so keeping a check of your M&Ms will help you prevent foodborne illness.

The best and convenient way of judging your M&M candies is with your sense of sight. While chocolates can last longer, they can lose their delightful taste overtime.

If your M&Ms are developing little white dots on the edges, it indicates that they are getting old. This process usually occurs because of dryness, which diminishes the quality of the candies.

Dry chocolate is perfect for cooking as it restores the flavors. However, you will never want to eat it plain as they will feel different in taste and not that enjoyable as fresh ones.

Additionally, you can check for any discoloration or molds to identify whether your M&Ms have gone bad.

Apart from judging the state of your M&M candies, you can also determine the quality with your sense of taste. If your chocolate tastes stale or rotten, it would be best to toss them out of your kitchen pantry.

Spoiled foods can increase health risks, and we recommend you to practice proper food hygiene and safety.

Humid conditions are not ideal for M&Ms, so it would be best to store them in a cool and dry place.

The company recommends users to consume their products with 13 months from the manufacturing date, which guarantees that you will get the best and more enjoyable taste in that period.
