Do coffee beans really expire? Coffee beans will never "go bad," which is why they are typically packed without an expiration date.
Classified as a dry good that can be stored for an extended period of time. It would take years for them to become stale, though they do lose their freshness approximately 7-10 days after roasting.
It would take years for them to go bad, they do lose their freshness approximately 7-10 days after roasting. This is because, during the coffee roasting process, beans undergo a natural process called 'degassing,' in which carbon dioxide is released.
If you've ever wondered why coffee bags have a hole, there is a reason. It is a one-way valve that allows carbon dioxide to escape but not oxygen or moisture to enter the beans.
Once the beans have released all of their carbon dioxides, they begin to absorb oxygen and oxidize. This process gradually deteriorates the beans and renders them flavorless. While the one-way valve temporarily preserves coffee beans, it will not keep them fresh indefinitely.
Unroasted green coffee beans retain their freshness significantly longer and can be stored for up to two years.
Roasted beans have a shelf life of approximately two to six months, depending on the type of coffee and your personal taste preferences.
When storing coffee, it is important to minimize the presence of moisture, light, heat, and oxygen. Whatever storage you choose, keep it cool, dark, and dry.
