Coffee Canister, Airtight Stainless Steel Kitchen Food Storage Container with Date Tracker and Scoop for Beans, Grounds, Tea, Flour, Cereal, Sugar Coffee bean preservation method: Some friends may ask, can coffee beans be stored in the refrigerator? Our suggestion is that if you put unopened coffee beans in the refrigerator, the temperature will decrease, and the oxidation rate of the coffee beans will inevitably slow down. However, if the coffee beans have been opened, it is not recommended to put them in the refrigerator. Among the important elements that affect coffee, moisture has the greatest impact on coffee taste. Coffee beans will absorb moisture and the taste will deteriorate to a large extent. The suggestion for the preservation of coffee beans after unsealing is to put the coffee beans in a special airtight container or use a special sealing strip (clip), and store them in a cool and dry place. The original flavor is longer. When choosing a coffee container, choose a product with a rubber ring on the inside of the lid, because the aroma of coffee beans is easy to radiate and it will also absorb the surrounding odors, so use a sealed container to store it. Warm Tips: Please rinse thoroughly before the first time use. Rinse with neutral cleaner. Hand dry after washing. Please do not scratch the surface with hard material such as steel scrubber. Please store in cool, dry places and avoid direct sunlight. Slow down your pace of life and abandon instant coffee Why choose our coffee canister?
