As far as gas is concerned, the specific gravity of carbon dioxide is the same as that of air. Therefore, in the same confined space, carbon dioxide precipitates at the bottom, while air floats at the top. After understanding this truth, when you choose a container or bag, you can judge its practicality.

Another phenomenon is that during roasting, coffee beans will release carbon dioxide. After roasting, the ripe beans will continue to exhaust for 30 days. This helps the coffee beans stay fresh because of the emission of carbon dioxide.
