Freshly roasted coffee beans release hundreds of chemicals in the form of steam. Coffee beans should have 1 to 3 days to ventilate and release these gases before use.

After roasting, coffee beans begin to lose flavor after a week; ground beans begin to lose flavor within an hour.

Coffee beans should be packed in vacuum bags with one-way vents to allow gas release without touching the air, so that the packaged coffee beans will retain their flavor for longer; vacuum-packed coffee beans will soon get worse once they come into contact with the air. But if properly stored, coffee beans can also stay relatively fresh for 1 to 2 weeks.
