Roasted coffee beans are easily oxidized due to contact with the air, resulting in deterioration of the oil, volatilization and disappearance of the fragrance, and then accelerated deterioration through temperature, humidity, sunlight and other factors.

Generally speaking, the storage period of coffee beans after opening is one month, and the drinking period of coffee powder is one week. Unsealed vacuum packaged coffee beans can be preserved for 4 months.

Coffee beans bought home should be stored in a sealed container, preferably in the refrigerator. Sprinkle some salt (for dehumidification) in the coffee storage pot to help preserve the aroma of the coffee.

Nowadays, most of the bagged coffee sold on the market have an one-way vent so that the gas from beans or coffee powder can be discharged to block the air outside. As the shelf life of coffee powder is shorter than that of coffee beans, try to grind coffee before brewing coffee, which can preserve the freshness of coffee beans and maintain the aroma of coffee.
