How Long Do Coffee Beans Last?
Keeping your coffee beans or coffee grounds in an airtight container will help them stay fresh longer. But keeping your coffee fresh isn't only about storage; it's also about preparation and packaging. Because some coffee isn't made to last (and you don't want it to), it's best to restock periodically rather than wait.
Pre-ground coffee or coffee you grind yourself will last less than coffee beans. Degradation of coffee molecules occurs naturally due to surface area and lack of protection in coffee grounds. However, with suitable packing and processing processes, this gap can be avoided.
Storing Your Coffee
The best way to extend the shelf life of ground coffee or coffee beans is to keep them properly. The best method to do this is to store your coffee beans in an airtight container somewhere cold and dry.
If properly stored, coffee beans can last up to 9 months, though their quality will gradually deteriorate. Coffee grounds kept in an airtight container can last months.
