Coffee beans are a precious ingredient, and their preservation is essential to maintaining the freshness and taste of coffee. Proper storage of coffee beans can extend their shelf life and ensure that every cup of coffee can present the best flavor. Here are a few key steps to help you properly preserve your precious coffee beans.
First, choose the right container. It is best to use an opaque, well-sealed, and non-porous container to store coffee beans. This prevents light, air, and moisture from entering, which can adversely affect the coffee beans. Glass jars or ceramic jars are both good choices.
Secondly, open the seal on the package before storing and reseal the remaining portion. This prevents air from entering the bag and slows down the oxidation process. If possible, it is recommended to transfer the remaining portion to a dry, clean and odor-free container.
Finally, when choosing a storage location, be careful to avoid exposure to direct sunlight or near high temperature areas. Both sunlight and high temperature will accelerate the oxidation process of coffee beans, resulting in loss of flavor. The optimal storage temperature should be between 15-25 degrees Celsius, and the relative humidity should be maintained at 60-70%.
