Fresh coffee is all about flavor, aroma, and quality—but without proper storage, your beans can lose their freshness quickly. When coffee is exposed to oxygen, moisture, heat, and light, it begins to stale, leading to a flat, dull taste. Coffee beans naturally release carbon dioxide (CO₂) after roasting, which helps protect them from oxidation. However, once this CO₂ dissipates, the beans become more vulnerable to air and humidity.
