How should coffee beans be stored for optimal freshness?

Storing coffee beans in an airtight container in a cool, dark place is the best method to maintain their freshness. When coffee beans are exposed to air, moisture, light, and heat, they begin to lose their flavor and aroma quickly. An airtight container helps to minimize exposure to oxygen, which can lead to oxidation and staleness. Keeping the beans in a cool and dark environment prevents them from being subjected to the harmful effects of light and heat, which can further accelerate the degradation of their essential oils and flavors.

While some other options do mention suitable conditions, they lack one or more critical factors that contribute to maintaining optimal freshness. For instance, storing beans in a refrigerator wrapped in plastic may lead to condensation that can damage the coffee. Similarly, exposing beans to light, as suggested in one of the other choices, increases the chances of degrading quality over time. Therefore, the combination of airtight storage in a cool and dark location is essential for extending the shelf life and preserving the taste of coffee beans effectively.
