Does Granola Go Bad?

Yes, Granola does go bad. This is because it’s a mixture of dry fruits and nuts. However, thanks to the dehydration process that the ingredients go through, they already have low water content so that Granola won’t get spoiled quickly.

How Long Does Granola Last?

Okay, so Granola has a long shelf life, but how long does Granola last exactly? The answer depends on the type of Granola you have and its storage conditions.

To help you determine when you can safely consume Granola, here are some of the granola shelf life guidelines you need to know about:

Store-Bought Granola

Fun Fact: Different brands have different recommendations on Granola’s storage time. Some products have a shorter shelf life because they contain ingredients that may go rancid faster (like nuts and fruits). On the other hand, other granola products have a longer shelf life as they were manufactured with additives and preservatives.

Typically, store-bought Granola can remain fresh for 6 to 12 months after being baked. This date is printed on Granola’s packaging.

Just a heads up, though. The printed date is not the expiration date which indicates the product’s safety. Instead, it’s a best-by date that tells you when you can expect the product to remain at its freshest and best quality.

Because of this, you can still safely consume Granola even if it’s past the best by date, but it may start to lose its quality beyond the bets by date gradually.

So how long past the best by date the store-bought Granola can be used for? Check out the following granola shelf life guidelines:

Store-bought Granola (Unopened):

– Best by date + 3 to 6 months (with additives and preservatives)

– Best by date + 1 to 2 months (with nuts and fruits)

Store-bought Granola (Opened): 3 to 6 months after opening

Homemade Granola

Since homemade Granola hasn’t undergone a commercialized dehydration process and has no additives or artificial preservatives, it has a shorter shelf life than a store-bought Granola.

The best way to determine how long it will last is to check out the storage period guidelines of the recipe that you’re following.

If there’s no available information about its shelf life, here’s the simple shelf life guidelines you need to know about:

·     Refrigerated Homemade Granola: 2 weeks

·     Frozen Homemade Granola: 3 months

Granola Bars

Like store-bought Granola, commercial granola bars are shelf-stable and have a relatively long shelf life of 6 to 12 months after baking. Because of this, you should also pay attention to the printed date. But again, this is a best-by date and not an expiration date.

On the other hand, homemade granola bars are like homemade Granola because it has a shorter shelf life than the store-bought version.

Take a look at the provided guidelines to determine the storage period of granola bars:

Commercial Granola Bars

–      Unopened: Best by date + 3 to 6 months

–      Opened: 4 to 5 days after opening

Homemade Granola Bars: 7 to 10 days (refrigerated)

Warning: Generally, Granola is safe to eat past the printed date. However, this is only true if the product is stored correctly and has no signs of spoilage.

How to Tell if Granola Has Gone Bad?

Because of this, it’s always a great idea that you examine it first before consuming or throwing it away. Here are the signs of bad Granola that you should watch out for:

1.    Off Smell

Granola has been dehydrated, so it has low water content. However, it does contain oil, making it go rancid or stale over time.

If Granola has an off-odor like old paint or rancid oil smell, then you should throw it away.

2.  Mold growth

The worst thing that could happen to your Granola is it gets wet. Aside from the fact that moisture can change Granola’s texture, it can also cause organic growth.

If you’ve noticed white or green fuzzy growth in the Granola’s surface or its packaging, discard it right away.

3.  Bugs and Other Insects

You need to understand that bugs and other insects are attracted to dry foods like Granola. So if you open Granola and find a few bugs, get rid of it right away because pantry pests can compromise the food’s nutritional value.

Pro Tip: If your Granola lost its crunch and has become soggy but doesn’t have enough molds, don’t fret because there’s still a way to bring back its crunch and freshness.

We’ll discuss how to do that in the following sections.

How to Store Granola Properly?

2 of the 3 signs of stale Granola can be prevented if you follow the correct storage practices. With that in mind, here are some tips on how to properly store Granola:

1.   Keep it away from air.

While the grains will remain okay when they contact air, other granola ingredients like nuts and fruits can go stale faster when exposed to air.

To keep Granola fresh for longer, we recommend transferring Granola from its original package to an airtight container or bag.

Pro Tip: If you’ve opened a pack of Granola, you can use a sealing clip to close it. You can also place it in a resealable bag for an added layer of protection.

2.   Keep the packaging sealed tightly at all times.

Another thing you need to do to prevent air exposure is to keep the granola bag or container sealed tightly at all times. Doing so can also help prevent insects from getting into the bag of Granola.

3.  Store granola in a cool, dry, and dark place.

High temperatures may cause the chocolate to melt and the oil to become rancid faster than expected.

On the other hand, moisture can cause organic growth and a soggy texture.

Because of this, it’s recommended that you store Granola in your pantry or any kitchen cabinet that’s not near any heat sources.

Other Granola-related Questions

1.  Should you refrigerate Granola?

You don’t need to refrigerate Granola since it won’t extend its shelf life. Also, the Granola will be exposed to moisture when refrigerated.

But if the Granola has chocolate chips and you need them in a place with warm temperatures, you can try refrigerating Granola.

2.  Can you freeze Granola?

Yes, you can freeze Granola. In fact, freezing Granola is one of the best methods for long-term storage. To do this, you can pour Granola into freezer bags or an airtight container.

3.   How to properly thaw Granola?

Thawing granola is pretty easy. All you need to do is let it sit out at room temperature. It will completely defrost within 1 to 2 hours when you do this.

4.  What are the risks of eating expired Granola?

Well, there are no dire consequences when you eat expired Granola. However, you might no longer enjoy it at its best quality when it’s already past the printed date.

Warning: If the Granola contains butter and is already years past the printed date, you might feel nauseous when you consume it.

5. How to make Granola fresh again?

As we’ve mentioned, don’t throw soggy Granola just yet. That’s because you can quickly revive it and make it fresh again. You can do this by microwaving it for 10 seconds at a time until it gets back its crunch.

You can also try baking Granola at 400 degrees Fahrenheit to bring back its crispy texture.

6.  How can I protect Granola from insect infestations?

In addition to keeping it tightly sealed, you can also wipe your pantry to remove spilled residue that may attract pantry bugs.

You can also layout bags of black pepper or other spices like ginger, garlic, or turmeric to keep insects at bay.
