What factors affect coffee bean storage?

Coffee beans are a commodity that is susceptible to environmental influences. Their quality and taste depend largely on storage conditions. The following are several important factors that affect coffee bean storage:

temperature

Temperature is a key factor that is essential to maintain the freshness and quality of coffee beans. High temperatures accelerate oxidation and cause the taste to deteriorate. Conversely, low temperatures slow down the oxidation process and keep the flavor stable. The ideal storage temperature is 10-15 degrees Celsius.

humidity

Humidity is also an important factor, too high or too low will have an adverse effect on coffee beans. High humidity environment is prone to mold growth and may cause the beans to become wet and rot; while low humidity environment may cause the beans to lose moisture and lose flavor.

illumination

Light can also have a negative impact on coffee beans. The ultraviolet rays in sunlight can accelerate oxidation and reduce flavor quality. Therefore, when storing coffee beans, avoid exposing them to direct sunlight.

oxygen

Oxygen is one of the main factors that cause coffee beans to deteriorate. When coffee beans come into contact with air, oxidation occurs, causing the flavor and aroma to gradually lose. Therefore, during storage, contact with air should be minimized and sealed containers should be used to maintain freshness.

time

Time is also an important factor. Although proper storage can extend the shelf life of coffee beans, long-term storage will still lead to quality degradation. To ensure the best taste and flavor experience, it is recommended to use freshly roasted coffee beans within 3-4 weeks of purchase.

Summarize:

In order to ensure the best quality and taste experience, it is very important to choose the right temperature, humidity, light and reduce contact with air. Only by correctly handling these factors and using freshly roasted coffee beans in time can you enjoy delicious and rich coffee.
