How Long Will Roasted Coffee Beans Last in a Vacuum Sealed Bag

Roasted coffee beans are a staple in most kitchens, and many people like to store them in a vacuum sealer bag. However, how long will roasted coffee beans last in a vacuum sealed bag? After researching, here’s an estimate of how long these roasted beans could last.

How Long Will Roasted Coffee Beans Last in a Vacuum Sealed Bag?

Ground roasted coffee should last for around six months in vacuum-packed bags, after which it begins to lose flavor and smell. However, several factors affect the freshness of coffee beans, including the best-before date, coffee storage, and the quality of the beans.

How to Store Coffee to Extend Its Shelf Life?

Coffee is a perishable item. It starts to lose flavor and aroma after just a few weeks. And if you’re not careful, it can go stale before you even realize it.

The problem is that beans are susceptible to heat, moisture, and light. So if you store the coffee in your kitchen cupboard or a vacuum-sealed bag in the pantry, it’ll spoil quickly.

Here are other methods that have been approved to increase coffee bean longevity.

Airtight Containers

Another effective way to store roasted beans is in an airtight container in a cool, dry place. This storage method can extend the life of your roasted beans by up to two weeks or more.

You’ll want to avoid using plastic bags for this type of storage since they don’t allow for air exchange, which will cause your beans to go stale quicker than if you were using glass jars or tins.


Freezing is one of the best ways to preserve your beans for a long time. If you are planning to buy whole beans, you can freeze them as soon as they are roasted. This will keep them fresh for a longer period.

You can also freeze ground coffee by placing it in an airtight container and then in the freezer.

How to Store Coffee Beans Correctly?

Coffee beans are an investment. You want to ensure you can enjoy your coffee for many years. When you buy beans, it’s crucial to understand how to store them and how long they will last.

Here are some of the things you should avoid when storing coffee beans:


Oxygen is another enemy of coffee that can cause it to go stale quickly. The best way to keep air away from your freshly roasted beans is by sealing them in an airtight container such as an empty glass jar or mason jar with a lid that fits tightly on top.

You’ll need to keep this container tightly closed for at least six months to get the full benefit from your roasting process.


Light can also harm your beans’ flavor and aroma by affecting their taste and appearance. This is why it’s important not to store them in direct sunlight or near windows where sunlight could shine through into the container. 

If this is unavoidable, try storing them somewhere dark and cool (like under a bed or near a refrigerator).

Heat flows through the package (due to convection), causing your beans to lose their flavor. 

This is why packaging materials like foil and parchment make excellent ways of preserving roasted coffee beans. They won’t allow heat to flow through them easily – they’re protective barriers that prevent damage while allowing enough light in so that the coffee doesn’t go too quickly!

How to Spot Spoilt Coffee?

Although consuming spoiled coffee rarely causes health issues, it does taste off. It is nearly impossible to tell fresh coffee from expired because the coffee retains its external appearance even after it has degraded.

So, how do you know if your coffee is still good?

  • Smell: If your coffee smells bitter or stale, it’s probably spoiled.
  • Color: If your coffee has turned brown, it’s probably spoiled because beans begin to oxidize when they’re exposed to air.
  • Feel the beans: If you rub your finger across the surface of a stale cup of coffee, you’ll feel crumbs that indicate that something has been added to the drink before brewing.
