How many days can roasted coffee beans be preserved?

Vacuum packed coffee

Most of the coffee bought is in vacuum-packed plastic bags. The vacuum process removes oxygen and carbon dioxide from the container, which keeps the coffee powder fresh. Once the container is opened, the coffee will be in good condition for only 7-10 days.

Grind coffee beans

If you buy back whole coffee beans and grind them by yourself, the coffee powder can last for 2 weeks. They are preserved in the same way as whole coffee beans in an airtight container and in a cool, dry place.

Refrigerated coffee beans

Many people mistakenly think that keeping coffee in the refrigerator is the best way. But this is not the case. Coffee can't stand moisture, air and extreme temperatures. When the coffee is taken out of the refrigerator, extreme temperature changes can affect the freshness. In addition, the condensation humidity will also make the coffee beans (powder) spoil prematurely.

A fully sealed or one-way valve bag can be kept for three weeks to a month, but it will reach the limit if the bag is opened frequently for 2-3 weeks.

Fresh coffee is a wonderful thing. Although you can buy freshly brewed coffee in a coffee shop, if you bake and grind the beans yourself, you can make sure you wake up every morning and drink a cup of fresh coffee at home. As for the storage time of coffee beans, it largely depends on the storage method used.

Unroasted coffee beans

Coffee beans can be kept dry and unbaked for several years. During baking, the oil of coffee beans moves to the surface and spoils quickly. Therefore, after the coffee beans have been roasted, the storage mode becomes particularly important.

Roasted coffee beans

Whole coffee beans that have been roasted and released oil can be placed in an airtight container and stored in a cool, dry room temperature. Whole coffee beans can be preserved for a month under these conditions.
