The shelf life of coffee beans and changes after expiration

The shelf life of coffee beans generally depends on their storage conditions and how they are handled. Generally speaking, unopened coffee beans can stay fresh for about 6 to 12 months at room temperature. However, once opened, the shelf life of coffee beans is greatly shortened, and it is generally recommended to use them within 1 to 3 months to ensure the best flavor and aroma.

When coffee beans expire, a number of changes occur. First, the aroma of the beans will gradually fade and become less strong. Second, expired coffee beans may taste sour or bitter because the oils in the beans begin to oxidize. In addition, the surface of the coffee beans may develop mold or discoloration, which is usually caused by a humid environment. Knowing these signs can help consumers determine whether coffee beans have expired and avoid using spoiled coffee beans.

To extend the shelf life of coffee beans, it is recommended to store them in a sealed container in a cool, dry place. In addition, avoid exposing coffee beans to direct sunlight and high temperatures, as these factors will accelerate the deterioration process of coffee beans. Through good storage methods, you can effectively maintain the freshness of coffee beans and enjoy more delicious coffee.
