Storage, noun: Coffee doesn’t react very well to humidity, foreign odors, oxygen and heat. All of these factors affect its flavors. In order to avoid this, it’s best to store it in an airtight and opaque container (e.g., glass or porcelain) and preferably at a constant and cool temperature (45-60°F). The refrigerator is only suitable to a limited extent because it’s relatively humid and is teaming with various odors. Coffee beans generally keep their flavors longer than grounds, which should be consumed within 14 days. Coffee beans are also used for odor neutralization in high-end perfume shops.
