Post-Roast Care and Storage

Once your beans have been roasted to perfection, proper post-roast care and storage are vital to preserving their freshness and flavors. The process of degassing is crucial in ensuring the quality of your roasted beans. During roasting, carbon dioxide builds up inside the beans and needs to be released to avoid off-flavors. Allow your beans to degas for at least 24 hours in a well-ventilated container, ideally with a one-way valve to release the gas while preventing oxygen from entering.

To achieve optimal freshness, store your roasted beans in an airtight container. Oxygen is the enemy of fresh coffee, as it accelerates the staling process. Look for containers with airtight seals and store your beans in a cool, dry place away from direct sunlight or heat sources. This will help preserve the flavors and aromas of your coffee for longer periods.

When it comes to the shelf life of roasted coffee beans, it’s important to consume them within a few weeks of roasting. Coffee beans are at their peak flavor within this time frame. However, if you find yourself with an excess of roasted beans, you can extend their freshness by freezing them. Place the beans in a freezer-safe container or bag and store them in the freezer. Before using the beans, allow them to thaw at room temperature to prevent moisture buildup.
