It’s important to keep your dark roasts properly stored to preserve your beans’ fresh roasted flavor for as long as possible. In order to maximize freshness and flavor, store them in an Airtight Container (View On Amazon) at room temperature. Keep them in a dark and cool place away from sunlight and moisture; as the light will ruin the flavors and the humidity will cause mould growth. Especially when buying pre-ground coffee, it is preferable to store them properly as exposure to air is bad for your beans. In general, freshly roasted coffee beans last for 2 to 3 weeks. If you buy whole beans, grind them right before brewing.
